TVS ECU / TCU Software Package | Stage 4 ECU - Stage 4 TCU – For VAG MQB platform vehicles fitted with the DQ250 gearbox, 2013 - Present

This software is custom made software for a vehicle with a big turbo or supercharger upgrade as well as heavily modified engine setup, including a built engine. Please get in touch with PERON HQ or any of our UK TVS Dealers regarding your setup and what performance gains to expect. While the TCU is increasing the torque limits to suit the extra power and torque from the ECU calibration, to ensure the increased power will not cause any additional wear on transmission parts due to the increased power output from the engine, As well as benefiting from the drivability upgrade.

TVS ECU Stage 4 software optimises the engine performance of the VAG platform vehicles. While the TVS TCU stage 4 software includes the Drivability Upgrade and further optimises performance of the 6-speed DQ250 DSG gearbox for tuned vehicles with the following engines: 2.0 T(F)SI, 2.0 TDI, 3.2-3.6 V6, 1.9 TDI, 1.4 TSI and 1.8 TSI  (2013 - Present).

While the DQ250 DSG system is known to be generally strong, reliable and easy to use, there are some known issues, which can hamper drivability, especially with tuned vehicles.

These include: lack of response (delay in shifting); harsh, unwanted kickdown and a less-than-smooth pull away from standstill. From the factory, Sport mode is too aggressive and high-revving for many situations, while in Drive, shifts may feel sluggish – both impacting on the drivability of the vehicle.

The TCU software removes unnecessary downshifts, allowing you to hold onto a gear for longer, but also increases the shifting speed, which provides a more responsive and enjoyable driving experience. With the clutch clamping force and torque limits both increased, the TVS DQ250 Stage 4 software can handle up to 750Nm of torque, when used with the mandatory TVS race clutch upgrade.

TVS Software must be installed at either PERON HQ or any of our UK Dealers premises. This software is not currently available as a home-flash service.
