    Throttle hangs at half throttle in wide open throttle run

    Scary ride. Back to messing with this 07 Grand Cherokee from Hell. Downloaded the latest beta and still the Scanner is still not working correctly. Made a wide open run on the street to see if the new Transmission was doing what we wanted it to. Let off the throttle and the vehicle kept ACCELERATING!!For 2 seconds it Closed the throttle to 43% immediately and then finally closed the throttle. At 43 % throttle it was still accelerating. Unfortunately The accelerator pedal pid voltage is not working Also injector pulse-width does not read correctly. Knock retard does now read but knock sensor voltages do not. I was working with the transmission, thus why I was using HP tuners. The (D) guys logging for engine seems to work correctly. Not sure why it held at half throttle. Its at 12:57 into the log if someone would care to look and give input. Thanks!!

    Just to let everyone know I had clicked enabled sensed Map. Disabled sense map, redid my tables and worked like a champ
