Pedal - Throttle Body Calibration

Post by Mark_Vaughan »

Gen III 5.3 swap in-progress... Relative beginner here... everything so far (in TunerPro) has been done on the bench, disabling VATS, minor changes re: cam, injectors, etc. Now that the engine is in the car, it starts, idles, runs fine, except...

With key on and engine off, at roughly 50% pedal travel, the (drive-by-wire) TB shuts down and I'm apparently going into limp mode. I can easily reset the code (U0107 - Lost Communication with TAC Module) with my scan tool, but I'm struggling to find where to look for pedal/TPS "calibration" settings that might address the problem. Does that exist in TunerPro, or am I looking for the wrong solution?
