...well?

I've been trying an 80mm BAMM that TTFACE made for me. So far, my findings are the following:

1. With the stock 3.0 bar fpr and the descreened stock MAF the idle value for the long term fuel trim was -2.2%.

2. I put a 3.5 bar fpr and left the descreened stock MAF. The idle value for the LTFT went to -2.8% which is normal since the car was running richer.

3. I left the 3.5 bar fpr and installed the 80mm BAMM. The idle value dropped to -0.9%. The car runs stronger at high rpm but lacks nerve down low when compared to case 2 above. Guess I should try the 4 bar fpr, what do you guys think?

YOu're fine. In fact, It doesn't get much better than those numbers...Adaptation is spot on. You might want to log block 217 (WOT run) and convert Lambda to A/F (LB x 14.7) and make sure you're not lean under WOT condidtions.

can these readings only be done with a VAG?

TTschwing

Yes, or some of the other Pocket PC based systems. VAG-Com is the most versatile though..
