    Torque measurement sensor

    Hope someone can help with this. I am trying to adjust the base pressure levels. I have a Radix supercharger and the torque curve is very flat after about 2000 RPM.....at least by seat of the pants feel.
    Can anyone tell me if there is a way to scan the torque measurement sensor? I'd like to be able to more intelligently adjust to pressures in the appropriate torque ranges and throttle positions.
    Thanks

    Re: Torque measurement sensor

    There are a couple of delivered torque PIDs.
    One is engine, another one seems to embody
    converter fluid multiplication (on A4s). I don't
    think there is a torque sensor per se, but the
    engine crankshaft position sensor's dynamic
    output (crank acceleration / deceleration =
    torque ripple) is somehow processed to make
    an average output torque value. Of somewhat
    questionable accuracy, but output nonetheless.

    For trans related params like TM, the one that
    includes the converter effects is the one you
    want; for engine-only load stuff I -think- you
    want the straight engine delivered torque PID.
