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.
