Title: MED9.1 biger maf calibration Post by: teobolo on December 06, 2017, 01:22:41 AM Hi to all , i m about to calibrate a 90mm custom maf in a Audi s3 -tfsi car .I have read the ME7.5 wiki in which maps to touch but i think i m missing somethinng.To be more specific i have not manage to found any MLHFM map on the med.1 i only found KLAF & MSHFMTPH should i start from those maps? and then finalize idle and low loads corection with KFKHFM ? i m open to any income .

Also the MAF output isn't a voltage anymore (uhfm_w) but a PWM signal (tpmshfm_w). so i should start with MSHFMTPH ? Should i calculate how much % biger is the maf housing diameter accoriding to oem housing and then multiply that value to MSHFMTPH?This is the way i calculate biger maf calibration in to japanese cars .

There is a dos app that will load the map automatically find the maf scalar automatically , ask for the old size and the new size and increase and dump the modified file..

Title: Re: MED9.1 biger maf calibration Post by: teobolo on March 22, 2018, 01:05:45 AM Is your maf calibration sorted? Yes, with the maps o mention and some fine tuning from FKKVS it is fine |
