Tuned car throwing Increased Emissions?
hey
my car is catless and running an AA tune, i picked it up from the dealer and on the way home it threw the increased emissions code and seems to be running rough. my sa knows and was told explicitly not to update the car and says he didnt...he needed to change a steering sensor and said he coded exclusively for that and touched nothing else...i asked him this four times and every time he said he didnt recode the whole car.... the radio presets were gone and the trip was reset when i got the car back, thats all i could tell. was it recoded and i need a new tune or is it possible that the tune is still there and its throwing increased emissions caused by an actual problem...car is not being driven now thanks for the input guys

No problem before dealer, problem right after? He most likely did re-flash it back to stock, I'm not familiar with this but does AA use a different ECU or they just flash the one already in the vehicle? Regardless of what it is, contact AA and work it out, don't bother causing too much commotion at the stealership because you don't want to void your warranty, especially in Canada.
Side note - I'm actually surprised your warranty is still intact when they know you are using an aftermarket tune.. Let us know what happens! |

thanks
yeah, i assumed they flashed it. but i told him when i dropped it not too, and he said he went back himself to make sure theyd only code for that sensor, etc... wtv, nothing i can do know but get it reflashed, i was just concerned that maybe it was something more serious considering that he is so adamant that he did not...

Have you hooked up the car to an ODB II ready to just see what codes it threw?
Its possible the tech forgot to deselect the DME from the programming station if he was told by the SA. Not cool any how. Anytime my customers come in and tell my SA not to flash the DME he puts a sticky note on the hardcopy saying not to program DME and I'm usually the only one who works on it.

If the car is running rough and the check engine light is on, that's an indication that its NOT the tune and that you were NOT flashed back to stock.
If you were flashed back to stock the CEL would be on for cat efficiency, but the car wouldn't run poorly. It's quite possible that there is an issue with the car that is not tune related, and the check engine light is on for something than cat efficiency. First step is to read the codes and determine if the cat efficiency error is there. If it is, your tune was wiped out. This doesn't explain the poor running. If cat efficiency isn't there, tune is still there and CEL is there for some other issue (probably o2 sensors/cam sensor) that needs direct attention. Re coding a steering angel sensor does not require reprogramming any modules (which would be the reason for losing the tune). This would have probably been a seperate operation. As dbarnes said above, if they try to program (not code) a module, it will overwrite the other ones because the dealer doesn't have the tools I use which allow me to selectively update to whatever version I want to load.

I think Omar has left or is leaving AA...that email might go unanswered. At least this is according to a thread that Omar posted in a different forum.

No reading comprehension fail on my part. Nothing above says the dealer reflashed to stock. All that is above my original post is the suspicion that maybe the dealer reflashed to stock -- an act the dealer expressly denied when asked. The only reading comprehension fail is on your part.

i just noticed the idle on start up bouncing around much more than i recall, at least since my tuned days...but this was on first start up, and the shop that did my tune told me its best not to drive the car if the tune was wiped and its catless cause it could cause damage, running too rich etc....what do u think mike? i havent driven it since then, and thats where i am basing my "running rough", possible exaggeration, from.... i havent hooked it up to a scanner, all i get is increased emissions in idrive, i know this means nothing without a scan right? re omar: yeah, i still havent received any reply, i guess, i ll just call on monday... thanks guys.

If he sold the company? Omar does not own Active Autowerk. The Hughes own Active Autowerks. Mike and Karl are the sons who do most of the work. Omar is just an employee, though he has been there for several years and done some nice project cars for himself and to help advertise for AA.
