    2017 Whipple Mustang goes to a limp mode

    Attached is the original Whipple tune and WOT log:

    01 luettu autosta.hpt

    06 kolmas veto puhdas.hpl

    Now with just some DTC's removed and fuel pump patch done, now goes to a limp mode.

    02 fuel patch.hpt

    07 nelj?s veto joku puuttuu ilmeisesti tarttee p?tsin.hpl

    How's that possible?

    No, this is not a swap.

    No.

    In the log it says: "Throttle angle source: Torque Reduction".

    I've now increased Driver Demand table a bit.

    The thing I don't understand is the fact that when flashed with Whipple Handheld, there isn't this problem. But when I read the tune with HPT and later flash the same, unmodified tune back to the PCM, the problem arises...See below:

    I think there were none.

    The first run log (on the first post) was done in dyno and no noticeable slip, so I doubt traction control was active (=disabled), but in the log it is there..

    In the screenshot above the run was made in a highway with TC button on.

    It was an issue with race mode. With that enabled in the tune, WOT runs had no problems anymore.

    If it through a wrench, there will be a code stored in a different module. A "U-XXX" code.
    Something with the airflow/torque model is wrong in race mode.

    The whipple calibration may have tables that aren?t defined by hp tuners. Best thing to do is to email support and see if there?s something missing that should be there, so when you program it with hp tuners that parameter isn?t being written. So since it?s throttle related my guess is it?s related to the throttle slopes. Is it using the whipple mono blade?
