description-icon Features

  • Unitronic Engineers identified gearbox originating torque limitations on the TCU side of the AL952 trasmission. In order to overcome these limitations, while ensuring proper torque management and operation, a 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 and further enhance the user experience.
