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.

Each transmission comes with a Tyre Calculator to assist you in setting up the correct speed and RPM values. You will have to enter parameters like:

Engine Max RPM
Engine Idle RPM
Final Drive or Diff Ratio
Torque Converter Stall Speed
Wheel Size like eg. 255 / 55 / 17
These values can then be entered in the software map.

Always start with Profile 1 in automatic mode as this is the profile in which you have to calibrate all the sensors, so that it is the same for the other profiles. Any calibration in other profiles is not available. Calibrations are not changed by loading maps. They have to be adjusted in real time on the TCU. (See Cloning in the manual to preload calibrations.)

Note. The buttons have built in denounce features. If you press them too fast they will not respond. If you press them during the Shift Time cycle they will also be ignored. If you press them too long, then you may activate map change if the 2 buttons are selected. So give the TCU ample time to complete each action before you press them again.
