    Wrench key lights "Limp mode" Mustang GT Procharger E85

    When I tune it in my dynapack there was no problem, but as soon I go and test it on street the wrench key start to light.

    It´s the first Ford I tune.

    Do I have to make some changes in the torque table?

    It´s makes 587whp.

    Somebody that can help me out?

    Thanks

    Martin

    Yes the Wheel TQ fix that issue.

    Now next problem.

    When I cruzing with the car in normal speed it start run realy bad after a while, I can see in the scanner that STFT start to lean -28% on Bank 1 and rich 66% on Bank 2 and then it start to lean Bank 2 -28% and rich Bank 2 66%.

    Can it be that the tune is to rich in that area? Did´t plug in my wideband to the scanner today...

    I get this DTC´s

    P2196 - Lack of HO2S-11 Switch, Sensor Indicates Rich - A HEGO sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC P2195

    P2198 - Lack of HO2S-21 Switch, Sensor Indicates Rich - A HEGO sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes

    50,000 is enough on the wheel max error or it can be more?

    If dbw is done right it "should" run on stock wheel torque error or real close to it.
