Hi guys,
Yes I did it and it works fine with the AUA ECU, but I'm not sure about the increased power as it needs different fuel mapping and if I'm not mistaking, ignition timing. Waiting to be corrected.
I got an ECU from Polo AUB, fitted it, but it wouldn't start. After checking and clearing the error code, same thing happens,
It fires briefly, then shuts down giving a code for faulty injection system.
I'm thinking, there must be a brand/manufacturer code or something, that's messing up things. With Volkswagen ECU in Audi, it gives error, but with Audi ECU in Audi it works but with AUA map. Also it could be a faulty ECU, I have no way of checking it.
Cheers!
