Modern VAG and BMW with DSG/ZF transmissions are fitted with a highly advanced TCU (Transmission Control Unit). The purpose of this TCU is to monitor and control all functions of the transmission, for example, shift points and torque limiters.
The TCU communicates with the ECU supplying real time data via the vehicles canbus network. When tuning an engine with DSG / ZF6/8 transmissions it is often advisable to tune the ECU and TCU at the same time to ensure the best possible combination of performance and functionality.
However, there can be limitations! It depends on the programmable parameters available within the TCU.

ADJUSTMENTOFTORQUELIMITER
When tuning an engine management system, torque limiters are adjusted. However, vehicles fitted with DSG/ZF8 gearboxes means the engine output will be limited by the torque limiters stored in the DSG/ZF8 TCU. With our custom written software, we increse the torque limiters to match the adjusted engine torque output.
IMPROVEDSHIFTINGSPEEDS
Shift speeds can be improved by up to quite signiffantly which reduces lag and improves acceleration. Quicker shift speeds produce a smoother gear change and improve paddle shift response times.
RPMLIMITS&SHIFTSETPOINTS
RPM limits and shift set points can be adjusted. The ajdustment of rpm limiter as part of the engine ECU remap is quite limited on a DSG/ZF6/8 equipped vehicle. As The DSG/ZF6/8 TCU will determine when the rpm gear shifts take place. Therefore to see the best results from your engine tune it is reccomended that the tcu is tuned to match your new engine map.
LAUNCHCONTROL(MODELSPECIFIC)
Launch control can be activated on some vehicles and will allow your car to make a near perfect launch every time. Reducing 0 – 62 acceleration times quite substanally.
FULLMANUALMODE
Even in manual mode, stock DSG/ZF6/8 software forces the gearbox to change up or kick down etc. Our custom written DSG/ZF6/8 software will give the driver full control preventing auto changing when in manual where possible.
