    Bosch MAF - peg limit

    Guest-only advertisement. Register or Log In now!
    What is the reading limit of the stock MAF in g/sec?
    I assume peg voltage is close to 5.0V (like 4.9 Volt?)?
    01 Allroad Tiptronic, TCU tune, mild stg 3 (350 HP) tune (stock injectors) KraftwerkTurbo TM1. Lower, Wider. Custom tip vent pod with Podi
    02 Allroad 6 spd, Kraftwerk Turbo TM6, 750cc, 3" MAF, piggy, FMIC, CM stg 5 (hate). 30 psi at 3600 rpm. Needs stronger rods (coming).

    I believe its around 4.9xx, the MAF has a +5.0V reference but I don't think it ever reaches that.
    IIRC the stock MLHFM table maxes out at 337 g/ sec.

    Bosch and Hitachi likely different, also found reference that some ECU act different than others.
    But could also be a density/speed effect (maybe the sensor measures volume/speed; hot air has a higher speed for the same mass).
    References are in the 320 to 340 g/sec range.
