back to stock - bad idle (ecu?)

[dualaudi]

From GTRS to stock. running a stock 557p ecu (possibly passat) even though i asked for audi 557p.

Do I need to recode to make this idle ok. (cold start barely get's it idling) warm or cold, give it some gas and it dies.

Is it possible I have the wastegate and turbo charge pipe vacuum lines mixed? Only thing I can think of that I could of done wrong.

I tried another MAF, exact same symptoms. Can't find my spare ICM - but all these components worked on the GTRS. (IM SO LOST) I have referee inspection wed, then judge on monday 9-20.

(will try and borrow VAG tomorrow)

have u done a throttle adaption? leave the key in the on position for 3-5 min

That was the first thing. (TBA)

Okay, so had a 3bar regulator in, tossed in my adjustable to bring it up to 4bar (~58psi). Does the exact same thing. When I try and give it some throttle it goes up then cuts back...

Any other ideas?

are you running the stock ecu on a gtrs with 3'' maf and upgraded injectors? if so the idle is going to be crappy because it cant adjust for the fueling and 3'' maf

title is " back to stock - bad idle (ecu?) "

Basically have to go into referee for inspection so I went completely stock. "completely" stock.

fixed... bad ecu... tonelee you were right on track... 17967 tba code couldn't be cleared from the spare ECU i purchased..

tossed in the pc16 runs like a champ... unfortunately that's the only ecu i have and probably won't pass smog...
