    Default B0720 change MPA?

    Can we mod a PID up to have table B0720 watch actual rail pressure instead of commanded rail pressure?

    Watching logs and B0720 does not work, because the fueling is based on commanded not actual.

    Any way around this?

    Thanks,
    Rob

    I know this was ALONG time ago but has there ever been an update for this issue?

    The question was a little confusing, if you mean can we change the ECM so that it looks at the actual rail pressure for that table, the answer is no.
    I no longer monitor the forum, please either post your question or create a support ticket.

    the problem is when you data log you cannot view anything other than 190 mPA while looking in the Tune to see where the map is because the datalogger will not log the correct PID for that specific table B0720.

    I was just wondering if I was doing something wrong here as I am still learning

    I also have this same problem with the SAE TP for throttle position

    I am running the latest and greatest build and updates to as well.

    Thanks
