Default When is UTEC firmware upgrade coming out for STi?

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?

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.

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.

Lucky I have UTEC over the top to fix things.

Short version-Get standalone knock detection.

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!

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

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.....

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?

QUOTE]

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.
