Turbo XS came out with the firmware upgrade for the WRX last year that resolved alot of the TPS crossover hesitation / stutter issues and I was told that they were going to do the same fo rthe STi. Anyone know if that is true and if so, when?

Thanks in advance

I think they have an arrangement set up such that whenever anyone asks, an angel falls from heaven. An angry angel that sets back the release date another month. At this point, therefore, we are looking at June or July...

...2012

^ Can't argue with that ^.

Turbo XS better do something fast because at the rate people are selling their UTECs on NASIOC, there will be no one who would own one by 2012 (crickets chirping). Almost seems like no one's buying Brand New ones to fund Turbo XS software engineers, because why pay 1000+ when you can get a used one for 400-600? :confused:

Just seems like the UTECs are pretty much circulating back and forth thru NASIOC among Subie owners.

I'm not happy at all with the delays in releasing the STi firmware upgrade.

If you look on IWSTI, all the new EM purchases appear to be AP. UTEC is fast going the way of the dodo.

I hope they have sti firmware upgrade soon to make the sti run better.

Subaru for TurboXS has gone the way of the dodo.

350Z and other stuff have taken priority.

Buy their knock light and see how bad ECUtek flashes are for knock and you wouldn't even know.

I agree with your first statement, but cannot figure out what you are trying to say with your last one. Are you saying that ECUtek flashes knock?

Yes mine ECUtek reflash knocked. It was flashed for 91octane and knock above 17psi but showed on the AM a sold 8.

UTEC,Knock Lite,knock link and tuner pro all showed the knock. I have all these in my car BTW.

Don't get me started on what the the A/F's where 9.0 to 11.3. Yes that's 9.0 coming on boost. :eek:

Lucky I have UTEC over the top to fix things.

Short version-Get standalone knock detection.

unpossible. reflashes don't knock.


;) :lol:

I'd really love to see TXS comment on this at least :(

No way, man. Stock WRXes are exploding all over the planet with anywhere from 5000 to 150,000 miles on the odometer. The stock ECU and its logic is total junk! :rolleyes:

The stock ECU and its logic is total junk!

ahh, but you're not using one anymore, are you?

;) :devil:

Nope. My engine completely sploded with the stock ECU, so I switched.

i have been hearing turboXS was going to release the firmware bak from last year. and i still don't see one until now...

if they don't come up with the new firmware that fix the transition problem and make full use of it's dual processor, then i don't think there will be any body buy utec "new"

even a half update would be nice.
i'll take a hybred crossover update and temerature correction and wait for W.I. and the other rumors that have been circulationg.

i'ts -6 proper here today, and this weekend we will be up in the 40's...
i am really, really, really, getting tired of switching maps for every 10 degree shift.
the only thing keeping me out of an AP for my next dyno tune is the fact that i'm a lazy bastard and dont want to pull out the freaking floor to uninstall it.

I agree and considering that they already have done it for the WRX it can't be that hard to change it for the STi... all the algorithims etc. are the same I'm sure.

Then later on add gear dependant boost control and Injector dead time adjustment ;)

Then later on add gear dependant boost control and Injector dead time adjustment ;)

They can do gear-dependent boost control....with a Gameboy and some other stuff for maybe $500, I think. There was a thread about this where many of us complained that the UTEC users should have this available to them w/o a gameboy and most of the ancillaries. The reply was, basically, that TXS can make it happen, and all we'd have to buy is a MAP sensor and EBCS, IIRC for maybe $200. But they were in no hurry and might do this in a future software update, which generally come every 1.5 years. I have to check my facts, but I think that was the outcome of that thread.

It was clear from that thread that they are making a business decision to develop other markets and focus less on the Subie market. I hate to admit it, but I think that it is a good business decision to diversify. That said, there will always (thankfully) be somebody else trying to break into the Subaru market with something better. Not that it does us stuck with this arcane UTEC any good.....

Bump...

When???/?/

Definitely not that far away and a little teaser...

- UTEC will be able to control 100% of the fueling all the time. 0% TPS.
- Transiton Smoothing with some clever settings. No more studders from CL to OL.
- Uses a completey different tuning method for more accurate fuel tuning. Hint VE Table.
- New boost control algorithim similair to DTEC.
- Adds many features seen in WRX 5.0.

I've alreay said too much but that should make you lick your lips!

Thanks xolosis. Hmmm... "VE table" - that sounds like a pathway to eliminating the MAF. Should I hold off on my blow-thru project?

We're planning out the next move with my project (already had discussions with most tuners in my area). I really need a better estimate on release date than "not that far away" - would it be possible to quantify that timeframe in months? Essentially, anything more than three months out and I'm an ex-UTEC customer. Seems that everyone is going with the AP/Ecutek, even for the bigger turbos. The UTEC's functions are nice, but consistent driveability in the STi / UTEC is a really big issue for those of us that don't drag race.

Also, how is TurboXS working with their reseller channel in making sure they're up and running with the new features when its rolled out? I don't do any of my tuning - I prefer to rely on the professionals (although that hasn't gotten me exactly where I want to be yet, it's my only choice since I don't have the time/experience).

I'm not saying that what you are saying wont ever happen but I've played with the sti 1.4 2006 firmware and it is pretty much exactly the WRX 5.0 firmware and the 1.4 firmware isnt even released.

Fair enough Aaron. However the UTEC firmware has now exceeded 1.4 by quite a few revisions. Another great feature is Tempature Compensation for those that get knocking, boost spikes when the weather changes.

I can't give a definite release date as I don't work for TXS!

Long story short;

There is new stuff.
You have not seen it.
It will be out soon.
It will work for all WRX/STI UTECs ever released.
No you, or anyone else for that matter, can not have it early.

Long story longer;
The software has been running around in the wild for a long time, but we are very hesitant to release something that is such a major change to any previous version without a lot of test time on the road. We have not forgotten about the Subaru guys, and for those that are somewhat worried, we still sell quite a few UTECs per month. More then enough to warrant the improvements to the UTEC which are hinted at in this thread and others. It works and works very well and the new UTEC software will allow end users things they thought they would never have the ability to do.

We stopped giving release dates a long time ago, and while this is sometimes frustrating it does prevent the emotional rollercoaster that is associated with an expected release date that is missed. In all honestly I can not give you an accurate release date because I don’t know it.

The standard WRX/STI/EVO utecs are however being phased out. There is a new product in the wings that will replace all of these in a single device. This makes for a better cost structure for us and increased value for our customers. It also gave us a chance to improve the hardware for all three previous UTECs in one generation.

-Nathan
oh and a baby kitten gets it every time you ask for a release date…

I hope the new product is not FAR superior to my UTEC. Maybe you could give us old UTEC users a date, so if we preorder I can get a decent amount of $$$ for the UTEC on eBay. As soon as it's released our UTEC's drop half in value.
When is the release date?

So what happens to those of us with a vehicle specific UTEC? Do we get a software update so we have the same thing as this "new product in the wings" or are we screwed and have to basically dump our UTEC which is now worth nothing and buy this "new product"

Yes

I sense that we are about to have the 2006-equivalent of Unichips. I dumped mine for $500. Two months later they sold for $200. Now the chip plus tuner go for ~$90 with harness.

You guys are not reading;

No you, or anyone else for that matter, can not have it early.

The only thing you miss out on with the older UTECs is some hardware capabilities that make it multi-platform transferable, slightly beefed up circuits and a faster processor that allow it to function on a multitude of platforms (my Elise for instance) additional inputs and outputs, and a new case design.

If you purchased the first released off the assembly line UTEC and managed to hang onto it this long the new software will make your collector's item work a ton better then it ever has. The only reason you would even want to upgrade would be because you purchased a 2006 WRX or some other car that required a different UTEC. This means you will be in the exact same position as you are now with the exception that your collector’s item is getting one heck of a software upgrade.

I do not know how I can be anymore clear.

That is good news for the early STI utec adopters. It's always been a mystery about why the next-gen STI utecs have dual-procs. I guess we can all sleep easy this weekend knowing that the first gen STI utec will not be limited in any way.

If the software update makes the UTEC better, the price of a used UTEC will go up. :)
Which is why I bought mine now.

Nathan, I sent you an e-mail the other day. I know you're busy, but a reply would be greatly appreciated.

Thanks.

Sorry, but it just makes me nervous when a vendor states that a product I bought is being "phased out". To me, that equates to "We no longer support this product" and "We are encouraging you to buy our new and improved product if you want to stay in the game". Is that what you are hinting at here, or are the older utec owners going to enjoy being supported after you release your "new product" (as I would assume)? And, is your "better cost structure" also going to be our better cost structure? ;) Just curious...

Oh, and can you give us a release date (X1000)? :lol:

Your continued efforts at improving our cat overpopulation problem is greatly appreciated!

do people honestly think they can buy a piece of electronic hardware and have it be both useful and supported forever?

My understanding is that the firmware update will support all versions of the hardware. Just reading between the lines with what TurboXS said, with hardware / design changes, the firmware may not be backwards compatable. Take a look at the Z. USB support?!?! Come on guys.. Let them be. They have a great product but just like anything else, good things come to those who wait.

Rainmanjam, you just completely contradicted yourself. So which is it, you understand that it will or will not support old hardware? Nathan pretty plainly said it this new firmware will work with all previous hardware.

Adding USB support is kinda minor in the grand scheme of things. This could be adding a single chip to the circuit board and involve no other changes at all.

Ride: funny you make a comment about hardware dying out in the very thread that talks about a rather massive update and upgrade to all old hardware.

The only phasing out I'm inferring is that all future UTECs are application agnostic, i.e. you will use the same hardware for an EVO and STI. Right now UTECs only work for one car at a time. All old hardware is getting brought up to date via software.

Adding new features to new versions of hardware != old hardware stops working or loses functions

How any of this could be considered a bad thing is beyond me.

i have been a very satisfied utec owner/user/tuner for over three years... not as long as some, but probably longer than most.

i am comfortable with the fact that it will not have software updates and upgrade support forever.

in the meantime i enjoy the additional features that periodically get added/updated, and consider them gravy.

i can't wait to see the new stuff, but i have to. :lol:

Bump... to slay a kitten.

Will I need to get retuned after this software update?

Will I need to get retuned after this software update?

Go read the 350Z UTEC manual. Based on a discussion, I'll assume that the new firmware will work just like that one. So YES....you will need to get retuned if running in a MAP based set up. Looks like theres quite a bit of ways to skin this kitten LOL!!!

I would clarify... You will only have to retune with the new firmware if you go with MAP/SD tuning. I assume there will be some nice new features that will work with an existing tune, such as temp. compensation and crossover smoothing.

These are my guesses/assumptions not based on any actual beta...

OK Nathan, not trying to put your feet to the fire or anything. But I have an appointment to get my STi tuned by a pro in a couple of weeks. I'm not having any serious issues as is, but have been told that she would benefit greatly from a good tune.

So, if you would be so kind, could you pls advise? Should I put off the tune for now and wait for the new f/w release? Or go ahead and do it, then spend another $XXX to do it again next time Mr. Wizard is in town?

Damn the kittens!

I did my GT30r upgrade in March of this year. I also asked if I should wait for a tune. The answer was wait. I decided not to and am glad, or I'd still be waiting.

Yeah, but.............which F/M are you talking about? I think the newer STI (WRX equivalent) was probably only in the plans and then they began with the newer MAP version. I'm holding off on my personal stuff I can tell you that (Nathan, come on man). I trust that it'll be soon enough.

The software is finished.
We need to clean up the documentation for the new features as well as write up the 2006 WRX utec/delta install guide which should happen this week. I was on vacation for about the last 2 weeks, so some of this slipped back a bit.

From here on out any cars tuned at TurboXS will be tuned on the new software. I will make the software general release when I have the documentation finished up, so you should all see something soon.

I can’t say enough about how well Will in Australia did with this utec update. You will all be very impressed.

The soon to be released UTEC software includes, but is not limited to, the following features;

1. Speed density fuel mode (note this is not the same as the 350z, it actually uses a VE table system so it is a bit more advanced then the Z software and a little easier to tune)
2. injector dead time compensation
3. Independent flat shift and launch control RPMs.
4. closed loop boost control similar to the DTEC-BC-PRO
5. 3d spare solenoid output control
6. etc, lots of etc

This software is only the start. You’ll all be bidding adieu to the HyperTerminal interface and saying hello to windows based real time tuning soon.

good things come to those who wait.

Nice, Nathan. Can't wait!

Will that SD mode be for all loads/rpm or will the MAF still be needed for idle and part throttle?

Todd

Yes there is much more to come. We have essentially hit the limit of the current software for our desired needs and have decided to re-write all the code with a GUI in mind. The base code needs to be upgraded to help the device function across multiple platforms so that we do not have to have multiple versions of the 4cyl code to support any longer. We will have a more universal base code and GUI that is configured in windows for each individual platform. This approach is simply more efficient. Your current UTEC will run the same code as the new Delta device, but you will not have all the hardware required for your current UTEC to be portable. The 2006 WRX however does receive the new hardware called the Delta. This hardware will be portable to other platforms; however the current software shipping on those boxes is not ready for anything beyond the 2006 WRX.

The GUI is going to make for some seriously cool tuning options that we have all dreamed about, but haven’t been able to implement with the current firmware.

Nice, Nathan. Can't wait!

Will that SD mode be for all loads/rpm or will the MAF still be needed for idle and part throttle?

If you choose to attempt the removal of your MAF you'll need to wire in a temperature sensor to the stock harness. I don't personally recommend the removal of the MAF in a big turbo system, as I’d rather see it in a blow though system so that we can use it as a reference to help smooth the idle ranges, but we've had cars where the signal quality was so poor that we essentially ignored the MAF signal from idle to redline (although it was still plugged in).

My jaw just dropped... Freaking Awsome.

If not, hows about you OPEN up the software. Start a sourceforge open source project, supply the new APIs to interract with the UTEC and let *us* nerds at it.

Ohh.. make it a nice API, fudging VT100 commands is kind of a pain.

Is the SD closed-loop at part throttle (and possibly idle), or does it rely totally on the VE table? If it's not CL with SD then I can see why the MAF mode with CL would still be useful for idle and low load.

I have been running this new software for 2 months now. It pays to play with the boys at SEMA ;)

I have ECUtek under the UTEC all tuned by Jarrad at PDX on 12th may. My car was the first with the new software that Jarrad had tuned. ALL on the Hush hush. :devil:

Result
Car drives smoother than ECUtek. Will has done a great job on the software rewrite. WI capable on Map 5 is nice but I have Aquamist 2d already.

Opinion among us after my tune was that this software release is a big as when the very first UTEC was made for the WRX.

ECUtek, access and Hydra be very very afraid. With Windows just around the corner your history IMHO. But I knows nothings

I would assume that Map 5 solenoid control could be used to fire a set of secondary injectors too (with an adequate solenoid), right?

Cross platform support would be soooo nice, but not at the cost of pushing out the release of what they have working already. It would be great to see it eventually though, but mainly for selfish reasons (my 'tuning' laptop runs linux). Would be nice for Mac users as I am sure there are some out there.

Did you happen to speed up the frequency of the PWM boost map 5 feature? 13hz is really low for driving something like a WI system.

That is a pretty good question. We have been playing with increased frequencies on the latest version of the DTEC software. I wouldn't be surprised if Will did this, and if he didn't it may not be too late to code in a higher frequency. Do you have a suggestion? In the windows release this should be a user definable parameter, but we are still limping along on the terminal based software for a bit longer.

For the rest of you, Mark (wombat) knows a bit more about nothing then he lets on. :)

I would like to see it pretty high - like 400+hz for driving aux. fuel injectors. For WI I would thing that 50hz-100hz would be enough. I wonder what frequency the Aquamist MP2 and the CoolingMist controller use. Configurable would be best or maybe two choices of frequency.

Edit: I meant 400hz - forgot to multiply by 4 cyls.

^^ I think that sounds about right. ~75hz would probably be a good number for general use. Maybe we can get Richard L to chime in. I know he's commenting on speed before.

Just trying to wrap my head around this one.

In the 4 stroke cycle you get power every other revolution.
Now, I assume that cylinder pairs are interleaved in the subaru so you get 2 cylinders of power on each revolution. Correct me if I am wrong here, as I dont know for sure.

If that is the case though, then the frequency is:
7000 RPM (EJ257 stock redline) * 1/60 = ~116 Rev per Second, and if there is interleaving going on, then you get fuel injection on one half of the motor every revolution, therefore ~116 Rev per second -> ~116 Hz for the stock EJ257 redline.

Also, getting Richard L to chime in would be nice to confirm, because the Aquamist 2d mirrors 1 injector pulse, therefore it would run at half of the above frequency (~58Hz). Again, if I am not being a complete moron about the power delivery in the subaru engine.

At any rate, I am completely psyched about the new firmware! :D

Yeah, that's what I was thinking/calculating, but for me with aux. fuel injectors- all 4 firing at the same time (non-sequential), I would think that multiplying that 100hz by 4 (cyls.) would be the safe way.

For WI I would think 100hz is plenty.

We need to know the rated frequency of the aquamist solenoid to make the most of this. If we set the frequency to be faster then the solenoid's response your fine control goes out the window. The frequency required by the RPM of the motor is kind of irrelevant if the solenoid doesn’t react quickly enough to respond to inputs that fast.

...

Hmm sounds good! The main concern I have is will the hyperterminal interface still be available as an option? I don't like the idea of having to stick to a windows app.

Yep, I agree. Thats why I agreed that it would be great to have Richard L chime in. I just added my experience with the 2d system, so that we could see that they can run at ~58Hz or thereabouts and get a ballpark estimate. And since it is tied to 1 injector line, that is a function of motor speed and therefore able to be derived to give us that ballpark estimate.
But, again, we should certainly get the final word from the Aquamist guys and Coolingmist guys and whoever else you want to take into account out there on this feature we are discussing. I can do all the educated guessing in the world, but it is what it is and they have that info. :)

From the Aquamist website (http://www.aquamist.co.uk/cp/sys2c/sys2c.html):
"The system provides a pre-pressurised water line up to 8 bars and the flow rate is metered by our latest High speed Valve (HSV). The inline valve is made of high grade Stainless steel and capable of achieving a cycling rate of over 250Hz...

...The HSV has a coil resistance of 13 ohm, it is suitable to be driven by the standard fuel injector signals, including the "pulse and hold" driver. As the designed operating cycling speed of the valve is over double of the standard fuel injectors (250Hz+), it is not necessary to use low impedance windings."

WHY DO YOU WANT IT TO BE DEAD? Dude, why ask such a silly question?


It's not a silly question. It's a silly rhetorical question. :cool:

I don't believe a lick of what is claimed about a release until it's on the TXS site. Even then I'll still be sceptical.

Im sure it will use a hyperterminal type connection to do everything just like the UTI Project.

Well, OK then. As long as it's for a good cause!

According to the Aquamist MF2 controller's manual online (http://www.aquamist.co.uk/cp/mf2manual.zip):

Fuel injection mode: pulse width = 12ms (or 83hz)

Water injection mode: pulse width = 75ms (or 13hz)

Since the Aquamist WI solenoid valve is good up to 250hz, my vote would be for 75 - 100hz PWM on map 5 so that the UTEC could work with both fuel injectors and the Aquamist water injection solenoid.

Are you sure of those numbers? They will be correct only if what you refer to as "pulse width" equals the time for one complete cycle. If, on the other hand, the "pulse width" equals the time for one positive (or negative) portion of a 50% duty cycle waveform, then you are looking at 41.7 Hz.

I don't know why it would be rated at 50% duty cycle. But no, I'm not sure of those numbers.

EDIT: I PM'ed Richard at Aquamist to see if he can help.

If you buy a new WRX one now it has the new hardware. The old hardware has already been phased out of production.

^ Good to know. Thanks!

The ideal frequency for thr hSV is between 50-80Hz.
Minimum is 30Hz. Below 30Hz, you wil srat seeing pulsed delivery. The rssponse time is slightly better than a fuel injector, on time =1.8ms and off time the same.

the 2d can be used for other PWM output as well, it is not confined to a fuel injector.

2c does not have an fault diagnostic circuitry and require about 1A drive current compared to 2d's 10mA.

Like I said, newb here! But why then did my UTEC come with a manual boost controller???

It shouldn't have come with a manual boost controller, it should have come with an auxilliary boost controller. The TurboXS ABC is a seperate valve that bleeds off additional boost so that the factory solenoid is able to hit higher boost values.

I don't know about the new firmware and CELs, but I'm hopeful!

I don't know about the new firmware and CELs, but I'm hopeful!

WRX firmware 5.0 creates a CEL that relates to the MAF. It doesn't do anything but it is still there.

If you have that cel with 5.0, you should download 5.0a from our website.

The STI firmware should be out next week as Jermaine said in his email, but that depends on how quickly the spare solenoid frequency change is made.

Of course your other option is to just make an appointment for a TurboXS dyno tune, because I’ve been installing this firmware on customer’s cars for a long time as there is no way I am going back to the old software after tuning with this on the update.

Nathan do you have a link to 5.0a? The website still only has 5.0. I also want to confirm, this new firmware will work on the WRX and STi?

chris, from what i can tell, don't bother with 5.0a

Yea I wasn't going to but I figured I'd have it on hand since I'm due for inspection this month :P

5.0a was a second release of 5.0 to try and help the people getting the MAF CEL. Sorry I forget the CEL #.

Aaron,
I'd have to check this (and please understand that the whole boost control system changes when you use the PID based control and I haven't looked at the old stuff in a long time) but I think 0 gain removes all duty cycle adjustment to reach the closed loop target. I'll get a firm answer for you guys if I can, but I think my above statement is correct.

Yes, that's odd how boost gain and the CLBs interact. Some people use boost gain of 20-30 and CLBs in the 150 range and get the same steady state boost as people running boost gain of 50-60 and CLBs in the 350-400 range.

and Page 3 of this thread...



The soon to be released UTEC software includes, but is not limited to, the following features;

1. Speed density fuel mode (note this is not the same as the 350z, it actually uses a VE table system so it is a bit more advanced then the Z software and a little easier to tune)
2. injector dead time compensation
3. Independent flat shift and launch control RPMs.
4. closed loop boost control similar to the DTEC-BC-PRO
5. 3d spare solenoid output control
6. etc, lots of etc

This software is only the start. You’ll all be bidding adieu to the HyperTerminal interface and saying hello to windows based real time tuning soon.

Right now the 2nd processor does nothing. I had a single proc utec and it controlled my DBW sti fine.

So is the STi version of the software also going to be labeled "5"? Or will it follow the existing STi releases, which are currently at 1.1?

Might as well call it 'infinity' at this rate.

Yeah, they work with the DBW'd STi's, but I could have sworn that the 2nd proc. was going to later be utilized for, or control more, DBW functions. Right now there is nothing, other than calibrating the TPS, that I can think of in the old firmware that utilized DBW functions. Now that the 2nd proc. will be utilized the UTEC can hold the throttle open while retatrding timing and dumping fuel, and give you a functioning ALS. That's just an example of what DBW control would do.

Right now it (STi UTEC - single or dual processor) functions of course, controlling fuel, boost, and ignition. But the 2-processor UTEC has a DBW switch or whatever that, in the manual says, is/was not currently utilized.

Since it seems like nobody knows what the 2nd processor is actually going to be used for I'll look for nmyeti's response.

To me, an important piece of choosing to go with the UTEC would be the ability to drive a spare solenoid for water injection. Undoubtedly the new hardware will do this since he's already stated this as a feature.

My question is, will any of the older STi hardware support this? If so, what hardware revision?

Thanks,
Mike

All of them. The spare solenoid driver on all public revisions of the Utec is the same driver circuit that the injectors use. All TXS does is map the spare solenoid to the MAP5 boost table.

I have emailed the firmware out to a few people who have special situations that the firmware will help alleviate. I have been installing this on cars that are dyno tuned at TurboXS for the past several months. The boss made a decision to not release the firmware last week because he wanted to give Will a chance to look into a condition where some of the test cars have reported occasional loud backfiring.

My vote was to release it to you guys as is with this noted as an open issue we will be continuing to look at, but I was overruled. In some ways it makes sense because the firmware fixes so many issues it would be bad press to release it and have a noticeable problem associated with it. We could go from “my utec hesitates” to “my car backfires” which is a zero gain situation. However, I am of the opinion that the one of the primary uses of the internet is to grip, so even if we fix the backfiring, there will no doubt be something else that is complained about and we’ll be in the same situation.

That said, the firmware exists, the manual is done, and I feel that we have something pretty special for you in terms of features and function. I can’t write the code and I’ve done all I can do so this is out of my hands.

If you feel that you have a compelling reason to have this software (other then “I want it now, Daddy!”) you are more then welcome to make your case to me via email.

I can already tell you that 2phless gets nothing but dead kittens. It is not fiction; I don’t like being called a liar.

So what compelling reason(s) would I need to report in order to get a copy of the software? :)

I'm really interested in evaluating the new closed-loop boost control to see if it improves my situation with my SZ55. Also, I still have problems with hesitation at the ECU/UTEC crossover even with v5.0 firmware.

Nathan,
I emailed you this morning, but not in regards to getting the firmware at the time. But now my email from this morning sounds like a very good case.

PLEASE!!! :D

The people tuning your car have access to the firmware. If they wish to use it, then they will, so you'll need to address the topic with them.

As for the rest of your questions in that email, I’ll get back to you when I have a few minutes.

Email sent.

Correct and they will be using the new firmware with my car. Guess I just wanted to make sure my ducks were in a row with the other stuff I asked about in my email.

look forward to your response.

That said, the firmware exists, the manual is done, and I feel that we have something pretty special for you in terms of features and function. I can’t write the code and I’ve done all I can do so this is out of my hands.

Yes! :banana: Thank you, thank you, thank you, thank you................................

Just had mine pro tuned, and still have that hesitation at crossover. You're saying that's going away, eh?

Email was sent from my work account mmurray_at_rfmd_com.
Please this car could really use the new firmware. I am not happy using the 100% load column for the 25psi and 30psi mapping.
Can a GM 3bar be used instead of the TXS 4.5 bar MAP?
The blow through set up is the TXS one. It worked for a while on the GT30. But now on the 35 it is not enough. Last dyno tune the car put down ~500whp at 30psi at F1 dyno. This new firmware wold really help this car.


TMS

So will you email me those kittens Nathan, or Fed-EX? Do they come with stickers?

I don't call you a lair. I do call you and everyone who's envolved with the subaru aftermarket annoyingly overzealous when it comes to their desire to look good to the customer. I've never met any of you who were outright lying to me, or even anyone who wasn't nice or professional. If I wanted to be buddy-buddy with a bunch of people I'd just have to meet subaru parts vendors. Ya seem like a swell bunch.

There is just no general desire for the suby aftermarket world to be accurate in my experience. Granted, you only said the firmware "should" be out next week. Maintaining prudently safe vagueness. The email from Jermain, which was posted second-hand, used the word "will" but, being second hand it may have be taken out of context... or perhaps brought back in a time machine from an email in the future. I can't say for sure.

Every TurboXS experience I've had has so far been just fine. I've had recent issues with several other vendors though. And after a year's worth of situations like; waiting 2 weeks for overnighted parts; being sent the wrong sized main bearings; recieving an incomplete, picked through master gasket set; being told items were "in stock" until I explained that I'd be there in the morning to get them; endless phone calls that led to zero information and sometimes mis-information (which is much worse and often much more expensive). And on and on... all from various retailers (none of which were TurboXS or Vividracing btw).

Thus my patience for you is perhaps misdirected, but it is short none the less.

So when I see fluff, I call it fluff. And you sir, along with those kittens, are fluffy as hell.

Can a GM 3bar be used instead of the TXS 4.5 bar MAP?

+1 for this question. I have a GM 3bar MAP sensor sitting in my desk, and it would be nice to put it to use.




Also, let me know what you want to hear in order for me to get the new firmware. :p

Every TurboXS experience I've had has so far been just fine.

so why all the negativity directed at them in this thread?

Negativity? Me? In a forum? N3VAR!

I'm just sticking to my "don't believe it 'til you see it" guns while the rest of you seem like you're going to miss cleaning smoke stains off your butts.

Will I end up paying for it in the end? Looks like it :rolleyes: . My car is, afterall, on strike until it gets a new video game for the carputer. Won't move an inch without it.

If it weren't for me, TXS may never have decided to shove this "I told you so" release in my face. So I think you all owe me a great big thank you for taking one for the team. Now get out there and and tune and find all the bugs so by the time I get a haxored copy of the firmware it'll be all ironed out.

Guess I am not worthy of the new firmware :(

Still anxiously waiting for my email response back, Nathan! :D

What don't you believe or not understand here? They've stated the truth. It's already running on quite a few (or at least a handful of) cars now.

Since Nathan has said publicly that a few folks have received it due to circumstance, testing, etc, I can tell you that I've been using this now for enough time to have it running very well (although one issue remains). I'm sure they'd like to iron these kinks out first. Plus there's the fact that you guys will need to relocate an IAT sensor to the manifold or pretty darned close if you don't have it like that now.

All of them. The spare solenoid driver on all public revisions of the Utec is the same driver circuit that the injectors use. All TXS does is map the spare solenoid to the MAP5 boost table.

TMS

That's excellent news. I was under the mistaken impression that this functionality was unavailable on current STi UTEC's altogether.

However the 3d map for a spare solenoid is new, correct? Is this functionality limited to a particular hardware revision?

Plus there's the fact that you guys will need to relocate an IAT sensor to the manifold or pretty darned close if you don't have it like that now.

OK. Once I do that, what should I do with the other 23 hours and 45 minutes left of my day?

I know. I'll hang around here and pick on you guys :banana:

Just because a concept car rolls around some test-track... that doesn't constitute its release. So why call this a "release." It's still in limited beta testing and not available to the general public. I.E., it is NOT released. Yes, a form of it exists. I get it. Dur.

I'm just stickin' up for the common man here. :p If ya can't play a little devil's advocate on a car forum then what has this e-world come to?

There are somewhere around 30-40 cars running this software in the wild. I won’t tune on anything else at the moment, so it goes on any car I tune. In addition I have sent it out (although I have not made any decisions on the emails I received from this thread) to people here and there. I have also given permission for PDX to install it on any car they are tuning if they so choose. Mark madden in Calgary has been running this for a few months. He received the software from PDX.

Call it fluff if you want, but I’ve done all I can do. The software is good. In MAF mode it is far better then anything we’ve ever had. In MAP mode it will allow you to actually make use of those big turbocharger setups without worrying about running out of MAF sensor. As far as my personal tuning is concerned, it is released. I just have not been given permission to widely distribute the file because some more work is being put into the backfiring issue.

Jermaine spoke out of turn a little in the email. He gave information that was accurate as far as he knew, but got vetoed by the people that actually own TurboXS. I work for Mark, and when he and Russell make a decision, we have to abide by it.

Lastly on directly addressing your devil’s advocate stance. I couldn’t care less if I look good. My e-peen doesn’t really get a rise out of people being impressed with me on Nasioc. I think if you’ve been following along for the 3 years that I’ve been posting from TurboXS you’d know that I am about as straight forward and dry in my posting as possible. I loathe fanbois and those that crave them, so my involvement in this thread wasn’t designed to inspire any good guy feelings or to pump up my standing in the community.

As for the requests I’ve received from this thread, saying that you can’t tune your car now because it idles and drives like crap on the current software is probably not the best way to convince me you’ll be able to get your head around the new stuff without spending lots of tech support time with me over the phone. The people that are going to get access to this are people that are going to be able to RTM and won’t need a lot of hand holding. There were several of these types of people that emailed me. However, I may have a new and final release version to send you in the next day or so, so I am holding off until I hear from Will since he made some software discoveries that will be implemented in the next version update.

This is why I am going back to the “I don’t know when it will be out, stop asking” stance. Every time we try to nail down a release date we are hung out to dry and take a credibility hit. I need one of those blinky-flashy things that MIB have to erase all memory of this thread “Step this way and please look into the light.”

This is why I am going back to the “I don’t know when it will be out, stop asking” stance.

That's all I ever wanted.

Thank you for your hard work. If my humor-turned-frustration-turned-ugly has honestly bothered you then I apologize. You seem like a "take it with a grain of salt" kinda guy so I'm sure you aren't losing sleep over the ramblings of a newb like me anyway.

My car idles fine with the old firmware. Crossover hesitation is so rare it's not worth chasing. I'm not in any hurry to use a potentially buggy setup any more than you are in a hurry to release one. So don't. Just give us the sweet-stuff when it's good and ready.

But the dropdown menu from the "software/manuals" tab on your site is a little touchy. If you have a little spare time, could you make it a little easier to navigate?

Thanks in advance.

Since there is a final release version in the works can you check on the MAF volatage displayed in the logger? Two decimal points instead of one should be an easy code chage. Meaning i'd like to see "4.69" vs. "4.6" in the loggers.

Lmao. You work in product marketing don't you?

My typical day:
Me: "Here's the final version."
PM: "Thanks. Can you squeeze one more thing in before release?"

I'm just messing with you, but last minute feature requests have a tendency to snowball if they're entertained. Which obviously does not help the release date since you have to test these new features as well, no matter how small. :devil:

Of course, I could entertain more of those requests if I weren't browsing this stinking forum so often.

If you couldnt change printf("%.1f", 4.89); to printf("%.2f", 4.89); in less then 5 minutes I would outsource you and your whole department faster then you can say mango lassi vegetable samosa.

edit: i know what youre saying.. but its just one decimal! :)

Ha. Yes, it's a small change. But, like I said before, small changes tend to snowball. One small change is not a big deal, but you can get stuck at the end of a release cycle making endless tweaks. I'd rather not turn this into a development process thread. I'll just leave it at; I would understand if they didn't entertain your request.

Peace

I'm pretty sure I didn't inspire this (I'm not that important ;)), but just for the record, I can tune my own car with the current firmware in place. It idles and drives fine; occasionally, I get a hiccup in ECU/UTEC transition, but it's nothing to complain about.

I'm just really interested in getting my hands on the manual and firmware, so I can start experimenting with new features! I'm definitely not one to tie up phone lines calling technical support :)

That's all... don't mean to offend or irritate or anything.

I'm right there with you too. I sent an email, and my car too idles, and drives just fine. I do have pretty bad ecu/utec hesitation, but I have good AFR's.

I have tuned several other types of cars in VE mode, and would like to start reading up on the new firmware, including any new parameters.

I do have a question about how the new firmware will interact with the TXS tuner though. Will it will log in the same manner, where the WBO2 reading is placed in the log?

nathan, along these lines, could you at least get us a copy of the manual so we can read up in the meantime?

ken

Yes I am curious as to how the VE implementation is carried out. I've tuned a few VE based systems and I am drawn to a few more than others. MegaSquirt sucks at it (it does work but I hate the interface) but things like the TEC3 get a thumbs up. They are pretty much all the same...

Check out the 350z manual which is online and you can download now. I'm sure there will be changes but I think it will give you guys some ideas.

+1. I would like to spend a good amount of time in preparation.

:rolleyes: fine.

Update: This is the truth as of this morning at 10:36am.

The bug is fixed, and the software is scheduled to be released tomorrow. It would be out today, but I’ve requested that the version number be upgraded to a whole number rather then the current 5.75abcdefg that would appear on the home menu.

Jermaine is building the web page today, so that we can, if possible get this out early in the day tomorrow.

I hope you guys will be happy with Will’s efforts. The new software is quite nice.


Edit: just because I've committed to a date, I am not responsible for whatever natural disaster that impedes the software’s release

Yes I have been killing kittens hoping my sacrifices would work.
Looks like they have. :lol:
Now we can tune that GT35 monster past the 5V MAF limit.:banana::banana::banana:

For SD will we need the 4 bar sensor or is the stock one ok?
