I haven't heard of a patch for the MAF. Really all I've seen were scaling mods.

The MAF scaling and AirFlow/HZ RAW tables are the same, just re-named and are using a different x axis scalings.

BTW: You should be tuning the "MAF Compensation" table not the "MAF scaling".

Correct. If its reading -8 that means the ecu is using the trim to pull that much fuel out so to help get that number back up to zero (or close) you just have to take some fuel out yourself so the ecu doesnt have to.

Great Info...

Just wonder does this steps on adjusting the MAF Scaling applies same to Evo's 4 5 6 and say if my Trims is within +/- 4 do i still need to adjust my MAF Scale?

Ive a 4" s/s pipe turbo compressor inlet, 2.5" i/c all round and 3" i/c on the bov til throttle body.

Im still finding a way to resolve my buck/super rich afr whenever i immediate full throttle.

Will get another MAF sensor tomoro and hoping for the best or i still need to adjust my maf scaling?
Gt3076r
S2 cams
575x600x50mm I/C
