My son is putting an LS1 into a 3rd gen. We needed a PCM and added a VIN to it to maqke the system happy. If we added a VIN for an A4 would it affect the tuning and running of the engine when in fact we have the M6 and not the A4? That's it. SImple question. They can't get the crankshaft to relearn and they're blaming the VIN.
