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.
Performance Software for your TCU Box Code is subject to availability.
Features
Unitronic Engineers identified gearbox originating torque limitations on the TCU side of the AL952 transmission. 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. At the moment, some MY2023 vehicles may have TCUs with locked bootloaders and thus are not tuneable through the OBD2 port. Support for these locked bootloaders is in the works. If you have a vehicle with the locked TCU, Unitronic offers Stage 3 ECU calibrations suitable for safe use with the stock TCU calibration in a slightly limited torque format.
