Service / TCU Remapping

TCU/DSG Gearbox Remapping

The TCU gearbox may be one of the best auto gearboxes on the market today. Its ability to change gear in no time at all while predicting the drivers next move is an engineering breakthrough. However, like all OEM systems their are restrictions.

Our custom TCU Remap has been designed to remove these restrictions and adjust the settings for a more performance enhanced driver.

Our custom TCU Remapping service alters the following parameters:

Increased torque limiter

When recalibrating the engine management system torque limiters will be increased, however if the vehicle is equipped with a TCU gearbox the engine output will be limited by the torque limiter set in the TCU module. The TCU torque limiter are raised to match the engine torque output.

Faster Shift Speeds

Up to a 20% increase in shift speed can be achieved thus reducing lag and improving acceleration. The quicker shift speeds also gives a smoother transition between gear changes improving paddle shift response time.

RPM Limits & Shift Set Points

RPM limits and shift set points in drive and sports mode can be adjusted. Doing so as part of the engine ECU remap is not enough on a TCU equipped vehicle. The TCU ECU determines at what rpm the shift will take place.

Launch Control

Launch control on some models can be activated. Launch control allows your vehicle to perfectly launch every time.

Full Manual Mode

Even when in manual mode the standard TCU software will force the gearbox to change up or down a gear. By custom tuning the TCU ECU we are able to give you full control preventing automatic changing when in manual mode the option to do this is specific to the vehicle model.
