Default HELP! My UTEC doesn't do anything...

Hi,
I'm kind of a noobie here so don't shoot out at me if I asked something stupid... I bought a Utec for my 03 WRX recently and I had a tuner installed it for me and he tried tuning it. He told me that the data logger and stuff are working fine, but for whatever reason, the changes he makes does not take effect.

He said he stopped the car, changed some fuel settings and started it up again. When he drives the car, he feels that nothing changed. Although the Hyperterminal is showing the changes, nothing happens. He said the car was running too rich. So he tried leaning out the afr mixture but nothing happened. Then just to give himself some clues, he made the mixture as rich as possible, still no changes.

He called TurboXS customer service and all they told him is that he doesn't know how to use it. He has been tuning ecus and all that kind of stuff for so long now, I do not believe him incapable of tuning a user friendly utec. He's really fustrated with the Utec and he switched me back to my Safc so that my car can run while I look for an alternative ecu.

Is he missing something here? We tried looking for the dipswithces but all we found were just 2 switches instead of 8 dipswitches. My tuner said it was probably a newer version of Utec. CAn anyone figure this one out?

Just for reference, my car's mechanical modifications are: Sti fuel injectors, custom uppipe, downpipe and full catless turboback, CAI intake, 255lph fuel pump, fuel regulator, avcr, safc, egt, vf-34 turbine, 24x3x12 fmic with custom charge pipes and that is all I can think about for the time being other modifications shouldn't be an issue I think. Oh yeah... maybe a rerouted battery to the boot of the car, but I don't think that'll cause anything...

Thank you in advance to all who have responded to my desperate cry for help...

On the back of the utec, there's a little dial that switches between map positions. If the dial is on 0(stock mode), you can do all you want to the maps in the utec, and nothing will change. Make sure the dial is set to something like 1, which would make the utec use the map in slot one. I think the problem is that the switch is either on stock mode, or your tuner is adjusting the map which is not in the slot which is being used. If your tuner is charging you what other tuners charge, you should probably switch to a tuner who has a lot of experience with utecs and wrx's. If you're not payin him much and are set on using him as your tuner, you might wanna ask him to read the utec manual.

I don't like safc's on wrx's. Imo, you'd be better off letting the stock ecu do its thing. As always, this is just my opinion, and I'm no expert.

peace

Sounds like a link to Mick's tuning guide is what your tuner needs

hippy,

My tuner has read the instructions over and over but he can't find out what was wrong... I checked myself and I saw the switch set to the 1 position and there was a map there.

Wrex,

Could you get me a link or something for this guide? I'd like to look at it...

Thanks for your time guys.

I hope you didn’t give this guy any money for these services…

Get it tuned by a professional shop who has experience with UTEC.

www.wrxhackers.com

You have to register to gain entry to the downloads forums. There is a UTEC section in there that has the tuning guide.

Here's a link to micks guide. I dunno how much it will help though since most of what's in it is in the utec manual, and the rest your tuner might already know. I dunno what to say if the switch is on 1, and you're using the map in slot 1(the map on top). Maybe you should check the parameters and make sure everything's ok? Some of the parameters(the temp compensation stuff mostly) can do weird things to fueling and timing.......

Start off by going to the dashboard and confirming that it's on switch 1 map 1.

Then make sure the map he's editing is actually map one.

If it's an OLF map, make sure you even have OLF turned on.

Because if OLF isn't turned on, he'd need to put in > -5 in the fuel map all together to even get it close to a 550 map in OLF, which at that point becomes +- tenths.

Is he actually saving the maps? You mentioned making changes, turning off the car, and then turning it back on, but nothing RE: saving the changes. Also, you don't need to turn off the UTEC between changes.

Or better still is he tuning in the 100% load column thinking its 100% TPS?

if your tuner doesn't want to take the time to read the manual..I would stay away from him.

TXS has all the rights to tell him to RTFM.

TurbojonLS,

He said the maps were saving fine, but it simply weren't making any changes. Like when he was trying to lean out some areas, it just simply wasn't making any difference...

nmyeti,

Can ou tell me more about the 100% TPS thing? As far as I understand 100% TPS is full throttle right? Those are adjusted by the ecu itself right?

Thanks for all this feedback guys!

RiftsWRX,

I am quite sure the maps aren't the problem, but about the OLF... I'm not too sure how that works. How do you swith it off? If it's off, why -5? I'm quite sure my car isn't an OLF type. Only the 04-05 are.

You really have to read the manual. You have pretty much no knowledge of the product, so it's pointless for us to answer your questions one at a time. Read the TXS manual, and read the tuning guide. Understand the product before you put it on your car and blow it up.

I hate to have to even say this...

Have your tuner take screen captures of the the dash board, the parameters->tuner constands, parameters->special constants, parameters->open loop fueling, the map he's editing (fuel map page 1 and page 2).

Post those up here, or have him email me the screen captures (admin@temporalrifts.com), and let's go from there.

With your mods, it would probably be best to be running with the utecs olf mode on.

What nathan was saying is that your tuner might have been adjusting the wrong areas of the maps, and that's why he didn't see anything happen when he made changes to them. You need to make changes in the timing and fueling maps according to load. The logs will show the load site and rpm range changes should be made in.

peace
