i think the title says everything but here are the details:
Audi tt owner has sold his modded car. Before doing it he removed all the mods that he have done to it so it was back to stock.
One of the interresting things he removed is his ecu with APR maps that you can switch between by using the cruise control button.
If i buy this 2001 audi tt ecu and install it on my 2001 AMK engine S3, will it work?
I suppose yes. but the other thing in my mind is that the tt is a us spec and my S3 is euro spec....anything wrong here?
