    My finished Freektune map.
    It is not possible for my Injector Duty Cicle to be 120% at 21.6psi at 6000rpm with my BNR S4.
    This is the objective of my post. Information on how to know the limit of the injectors when the Accesport miscalculates the percentage.
    Freektune already informed me that my Accesport did not correctly indicate the IDC, and one of my fellow Mazdaspeed, the same thing happens to them.

    The IDC % number is a value calculated by cobb, the ECU does not calculate fuel in IDC %, but IPW.

    If you log IPW you will get real numbers and can then calculate IDC% by dividing the IPW by crank rotation time in milliseconds. This does not account for other variables such as intake/exhaust valves opening/closing at various times.

    Go add injector pulse width to logged parameters and take a log, curious to see the results.

    Also stop posting snapshots of datazap, attach a .csv file or don't bother posting.

    Here are my last two logs from the final Freektune map.

    There is no injector pulse width in either log.

    These are the sensors that the tuner has indicated to me to make the logs.
