[Audi A3/S3] A3 ECU on a S3


Recommended Posts


I was wondering how well would the 180HP A3 ECU work on a 210HP S3. Would it work at all? Would it have to be reprogramed? How would I do it?

Reason for the question is, acording do AUDI, I have a burned ECU, and a new one is too expensive, and I would only find A3 used ones.

BTW: I'm in brazil.

Thanks in advance.
