    2012 GT500 Rev Hang - "Tip-Out Limit - torque source"

    This GT500 has an intermittent rev hang. When it does it it logs Tip-Out Torque Limit and rev hangs at 5k+ RPM. I am unsure the reason for this and want to sort it before I continue tuning. I have attached a log file and tuning file.

    2012 GT500, Whipple 2.9, DW750cc Injectors, 15% lower pulley, Ford Racing Twin 65mm Throttle Body, JLT Intake, Cat Delete...

    Car has excellent drivability and parking lot manners. Only issue is intermittent rev hang. Bypass valve operates smoothly when manually rotated...

    [ECM] 44770 - Torque Module: Master enable/disable for Torque based control actions. Turn this back on. From experience, GT500's will do very wacky stuff with this torque module switch disabled.

    I had the same exact issue on this thread I posted a while back

    Also ensure to get your torque tables dialed in and get the IPC error down close to zero as possible.

    Also make sure your throttle body data is correct. Here's the Throttle body Data courtesy of txcharlie

    Dial in your MAF as well.
