Gearbox Remapping

Gearbox remapping is the process of modifying the transmission of a vehicle through the TCU (transmission control unit) to achieve better performance. Not to be confused with a gearbox update, gearbox remapping is extracting and modifying the software data to alter the following:

• Shift Speeds – Increasing the speed at which the gearbox changes gear.
• Torque Limiters – Increasing the TCU torque limiters ensures the transmission cannot limit the performance of the engine.
• Hydraulic Pressure – Increasing the hydraulic pressure can increase clutch clamping pressure to prevent clutch slip on highly tuned vehicles.
• Shift Points – Changing the rpm limiter of the engine is often not possible without modifying the TCU software.

The most common transmissions we do are:

• VAG DSG / S-Tronic

• BMW ZF (6 Speed and 8 Speed)

• MB DCT

• Vauxhall (6T40 / 6T45 – 6 Speed)

• Vauxhall (8F50 – 8 Speed)

Gearbox remapping can achieve much faster gear changes, smoother changes, improved acceleration with increased torque, and increased fuel efficiency.
