    G8 GT (E38) Custom MPG PID

    This has been discussed before for the LS1, but looking for something similar for the G8 GT (E38).

    This is what SOundengineer developed for the LS1. What are the PID Sensor labels for the E38?

    this should get you MPG..and should compensate a little for fuel temperature a little bit..cause fuel weighs different amounts at different temperatures

    seems to be accurate in my car...


    basically its
    [MPH]/(([Injector Flow Rate]*0.132276)*[InjectorPulse Width]*[RPM]*8/(6175*(((([IAT]+[ECT])/2)+273.15)/299.8167)))

    with everything converted so that the units match appropriately

    No one?

    If the android and Ios apps can do this, HPT can I am sure.
