Air flow is not as simple a s fixed value at certain rpm. There will be massive difference at 2000rpm depending how much throttle is open. There are some readings in the log around 2000rpm with 45g/ms and the highest reading is 201.28g/s at 5120 rpm so the values seem plausible.
Lambda correction seams to be all over the place from -11.7% to +18%
I have made a chart in excel, it does not look that correction depends on either rpm or airlow so really don't know whats going on.
