ECU Swap from S-4 to A-6 2.7T
I am also curios to know if anyone has tried to swap the ECU from the S-4 to the A-6 2.7T in an attempt to get the higher torque profile from the S-4 into the A-6. Audi says you can't do this but.... It would be my preferance to just get a little more power from the A-6, and not go so radical as a 300HP chip.

I did it but my S4 ecu is chipped and now on a 2000 2.7T. You can interchange the ecu's on the 2000
models because they don't have the immobilizer on the car. I think that started in 2001.
