Title: RS4 MAF tables
Post by: s4man111 on December 28, 2022, 01:02:48 PM
Car is a stage 3 minus  2001.5 b5 s4, I want to swap my stock 73mm maf sensor over to this rs4 maf, Can i just copy and paste over the MAF tables from the rs4 K bin? Im running a hatachi sensor.

the rs4 k maps are for bosch, not hitachi.

Ok so what is the formula to add to the hitachi tables for adjusting to an 855mm maf

MLHFM  512x1 (16bit LoHi) from RS4 file
KFKHFM  14x14 (8bit) from RS4 file
MLOFS 1x1 (16bit LoHi) for Bosch MAF add 200

and pinout for MAF connector is different:

pin   Hitachi      Bosch
1      5V            -
2        12V (Kl.15)   
3           ground
4      signal       5V
5       -             signal

KFKHFM is much more intake geometry dependent than MAF dependent.

Thanks I’m starting with an rs4/b6 MAF Sensor and harness and will add these tables to the tune
