Thanks a lot again.
I flashed your values and here are some the results. Full throttle from 1200 rpm in 3rd gear:

Above at IAT 20 down to 15 C. And after about 60 km driving.

Here earlier at IAT 30 down to 25. And after mayby 30 km:

Stock A01G IAT compensation was reenabled in the above logs.

My reason for doing this was that my LTFT kept changing. One day +2.5, the next day -1. Lowering the OL timers didn't help. And setting them at 0 felt horrible.

My previous MAF was scaled at fairly low temperatures and without disabling the IAT compensation. Could the swings have been caused by IAT compensation influencing the scaling and subsequently messing up the trims when driving at different temperatures?

In any case, the engine seems to like it and it must be the flattest AFR curve I have had so far. It might be placebo and wanting to feel a difference, but it certainly pulls very smooth now.

Now waiting in anticipation what the LTFT are going to do. Hopefully, they will stick around 0 and remain stabile. Last pull I did on the way home had -0.05 LTFT.
