Title: Audi S3 - CDLA - MED9.1 - MAF rescale Post by: sieniu on June 30, 2018, 09:46:54 AM 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? ECU : Audi S3_0261S02721_1037501227_8P0907115AP 0010 Title: Re: Audi S3 - CDLA - MED9.1 - MAF rescale Post by: bzyk77 on June 30, 2018, 12:05:41 PM Make KFKHFM, work perfectly

Once you start to see changes, you'll be able to dial them in and calibrate the table properly Title: Re: Audi S3 - CDLA - MED9.1 - MAF rescale Post by: prj on July 01, 2018, 10:38:31 AM KLAF?

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