Title: me3.8.3 maf linearisation
Post by: Adrianb on December 24, 2017, 02:38:32 AM
Hello,
can anyone help me with maf linearisation on this ecu? It´s 150HP AGU engine and I have VR6 housing from mk3 and stock AGU sensor. I tried copy MLHFM map from vr6 file, but this is not good. Maybe someone have a tested solution here  ???

Thanks for any help  :)

with vr6 mlhfm and housing
- idle is lean (with stock map and stock maf housing it is OK)
- WOT maf readings are about 20g/s higher than stock

so this copy/paste method is not clear

thank you so much  :)

Scaling calculation is just an approximation. It would not be 100% precise. You can tweak data according to your readings or I can suggest you use a whole OBD1 VR6 MAF with it MLHFM data  ;) ;) ;) ;) ;)
