Hello, i have to calibrate MAF sensor becuse we change intake pipe, old pipe have area 33,51cm2, now is 38,48cm2, so i calculate that is positive change of 14,86%. I've tried to change KFKHFM and KLAF with this procentage change, but with not good results. With every change fuel correction is about +25%.

Can someone help with that?

If 15% isn't working, try 30%. Once you start to see changes, you'll be able to dial them in and calibrate the table properly

There are 2 KF you have to edit: KFKHFM, MSHFMTPH.

My experience: leave it original or take a bigger OEM housing with OEM sensor e.g. from TTS and copy data from this file.
