TCU Calibration Context
A TCU (Transmission Control Unit) calibration can complement an engine remap by adjusting shift points, torque limits, and shift firmness to match the increased power output. This is especially relevant when the engine calibration raises torque beyond the factory transmission torque converter or clutch thresholds.
TCU calibration is available for the ZF 8HP and is recommended alongside Stage 1 or Stage 2 engine calibrations for the best driving experience.
