Unitronic Stage 3 TCU Performance Software for the AL952 8-speed ZF gearbox is calibrated for use specifically with Unitronic's Stage 3 ECU Performance Software.

• Unitronic Engineers identified gearbox-originating torque limitations on the TCU side of the AL952 transmission. To overcome these limitations while ensuring proper torque management and operation, TCU Performance Software was required to run Unitronic Stage 3 ECU Performance Software for TTE1020 Turbochargers.
  
  Stage 3 TCU Performance Software calibrations necessarily increase the torque limiter to 1300Nm for seamless torque management and harmonious operation with the corresponding Unitronic ECU calibrations, enhancing the user experience.
