TCU Tuning

The TCU normally comes with standard gear profiles loaded. These profiles are just startup profiles to test the unit. Transmission setup differs too much to make standard maps for it due to the many variables like engine power specifications, final drive ratios, wheel sizes, fuel type and application requirements. In most cases you wall have to tweak maps or start over with a fresh tune. This section will guide you to setup different scenarios for your application like Automatic, Racing, Towing, Snow, Sand, Mud Low Range and Manual to name a few.
