VAG VL381- DQ381 MQB Gearbox Performance Tuning Stage 1

Description

VAG VL381 – DQ381 MQB Gearbox Performance Tuning Stage 1

A CVT Gearbox with good performance and comfort. We can provide the Gearbox with more Torque by modifying the TCU Software.

RPM Limits & Shift Set Points

RPM limits and shift set points can be adjusted in drive and sports mode. Adjusting the rpm limiter as part of the engine ECU remap is not enough on a CVT equipped vehicle. The CVT ECU will determine at what rpm the gear shift takes place.

Increased torque limiter

When tuning the engine management system torque limiters are increased, however if the vehicle is equipped with a CVT gearbox the engine output will be limited by the torque limiter set in the CVT module. We raise the CVT torque limiter to match the engine torque output.

NOTE: CVT gearboxes cannot take so much Torque as a DSG Gearbox.

Gearbox Performance Tuning Stage 2

A CVT Gearbox with good performance and comfort. We can provide the Gearbox with more Torque by modifying the TCU Software.

Quicker Shift Speeds

Shift speeds can be increased by up to 20%, this reduces lag and improves acceleration. The quicker shift speeds will also give a smoother transition between gear changes and improve paddle shift response time.
