I've converted an S5 N/A into an S5 T2, I used the N/A harness with all the proper T2 electronics, ECU, Boost sensor, AFM ect.

The car does run on the S5 T2 ECU, but its starts really hard and it rev's up real slow. So I checked the igniton timing and its like 60 degrees advanced at idle!!!

I swapped the S5 N/A ECU into the car and it started up right away and revs just like it should and the ignition timing is bang on 10 degrees at idle.

Is the T2 ECU screwed? Or am I missing something?


Thanks
