I was tried with 3 setups
1. A4SGE01C - MY02 OSECU Stage 1 91 Octane with IAM8
2. A4SGE01C - MY02 OSECU Stage 1 91 Octane with IAM8 with stock fuel map
3. Completelly stock maps
In log i see very low O2 sensor readings (0,77 instead 0,9-0,94) at the high RPM and low IAM at all. Can you advise me, what wrong with my car?
2002 USDM to lean on the high RPM

A lambda reading of .77 is rich. Anything less than 1.0 is considered a rich mixture. .77 is approximately 11.33 afr. Which is pretty much what these cars run in stock tune.
However I don't believe the stock afr is certified to that range. so the readings may be off. a Real WB would tell you for sure
