The complexity of today's modern vehicles generally incorporate a TCU and an ECU both designed to achieve maximum performance from your car.
It is normal practise to remap the ECU on all vehicles but by also remapping the TCU, greater overall efficiency is achieved in the following areas :-
- The engine is unconstrained by the improved gearbox.
- Changing the TCU settings enables improved gearshift points and therefore speeds.
- By raising the hydraulic pressure, this in turn raises the clutch clamping pressure which helps to prevent clutch slip.
- Features like Launch Control, Full Manual mode and Kickdown Delete are all unaffected by gearbox mapping.
