I want to know if there is any down side when using MAF from 400 rpm instead of 4000
I want to change table B8024 to 400 or so in a boosted car with 12 PSI because whan i try to adjust fueling before 4000 rpm it will affect the high rpm region because the area before 4000 rpm is calculated between VVE and MAF
I don't want to modify the VVE table because it seems to be complicated in E38
Thanks in advance
