    Default {b0120} Question

    Since this is based on RPM,Mine is at 4000rpm,If I were to raise it for example to 5500rpm,Would the PCM use the VE table up to that RPM instead of up to 4000rpm? Or is this something else?.......................Paul

    My understanding is that above B0120 the PCM uses MAF only,
    and below B0120 the PCM uses a combination of VE and MAF.

    So what if you raised B0120 what would happen?............Paul

    If you raised it to 5500, then the PCM would use a combination of VE and MAF since most of your driving would be well below 5500;
    above 5500 PCM would use MAF only.

    If you're running SD then nothing happens if you move it up.
