    I'm more interested in this:

    I use it to actively back calculate volumetric efficiency based on injector size, pulse width, and actual lambda from the wideband.
    I spent some time on trying to do the same a few months back but never had it working quite as expected.

    So, instead I just setup a PID that is "GMVE" x a correction factor based on wideband/commanded lambda values.

    Seems to work relatively well if you filter out shifts, etc.


    Do you do much transient fueling tuning? I'm fighting a quick lean tip in / long rich tip out on throttle changes.
    Post a log and tune if you want help
