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?
