A friend of mine has a '00 GTI 150hp 1.8t AWD (narrowband) 5 speed.  I stuck a immo defeated Audi TT 180hp ATC (narowband) ECU in it, and it runs and drives fine, but has CEL and EPC light.  I forget what the codes were, but the car drives virtually flawless, and noticeably has the extra power from the 180hp stock TT tune.  Injectors match, Maf matches, etc etc.  I've since tried to find a proper definition of each file in the various threads here to translate the necessary bits from one file to the other so whatever its mad about from TT to GTI is no longer an issue, but I cant seem to find anything for either file thats accurate.  I could even tweak the AWD file from stock like i have for my own wideband file, but not having a definition for it keeps me from doing so.  Does anyone have any accurate definitions?

Thanks in advance. 

the narrowband tt has a different pinout for the smaller ecu plug. the ecu grounds a relay on the cl ecu to power the throttlebody.
