I would try changing  FKKVS till stft/ltft are in order..than lanfa and bts

Thanks for reply
I am thinking about FKKVS but it's still just a correction factor.
Ideal - I want to get my ECU know that there is more air mass flow at higher RPMs.
Because without MAF ECU doesn't know it.


If ECU only uses KFMSNWDK, Why Angle ends at 70%? Where is WOT?

Camshaft and headers makes my AFR at WOT about 14-15.
Inverted at lower rpm and low Load richer AFR.

Thanks a lot

Yes it does

Thanks

Thanks for the reply
I know that is possible to calculate air density with IAT and MAP sensor and then with the throttle body position, pipe diameter and engine volume size you know your air charge. (theoretically)
But there have to be some factors or maps to determine accurate air charge.
For example with two different camshafts - at WOT ... MAP sensor = atmospheric pressure / IAT (same for both) but different air charge for each at random RPM.

I have custom made intake manifold prepared but without right correction its useless.

any idea what map or factors or way how air charge is exactly determined?

Thanks a lot for help

Sensors in this order
