Hows it going everyone, new guy here to learn about the Motronic ME7.1 ecu. I got myself an 01 B5 A4 with the 1.8t and want to learn about tuning these computers now. I have about 8 years experience tuning megasquirt on mazda's, but after almost 20 years of seat time in different mazda's i jumped continents and went German now. Hope to learn something hear I always enjoy learning and teaching myself something new.
