TVS Tuning Stage 4 DQ380/381 DSG (S-Tronic) software – for tuned VW/Audi vehicles 2015-on, including Golf Mk7.5 GTI/R and Audi S3 (8V)

Transform the performance of your 7-speed wet-clutch DSG (S-Tronic) gearbox

TVS Tuning Stage 4 DSG (S-Tronic) software highlights:

  • Clutch clamping force increased to handle up to 850Nm (requires mandatory TVS race clutch upgrade)
  • More responsive/smoother shifts with better drivability in D and S modes
  • Faster shifting speeds (up to 8000rpm)
  • Torque limits raised
  • Unnecessary/harsh downshifts removed
  • Improved clutch cooling/heat management
  • Fully customisable

The TVS Tuning Stage 4 software includes the Drivability Upgrade and further optimises performance of the 7-speed DQ380/381 DSG (S-Tronic) gearbox for tuned VW/Audi vehicles with the following engines: 1.8 T(F)SI and 2.0 T(F)SI 2015-on (the latter most commonly found in the Golf Mk7.5 GTI/R and Audi S3 (8V) 2017-on). With the mandatory TVS race clutch, it will handle up to 850Nm of torque.

While the DQ380/381 DSG (S-Tronic) 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 slow reaction when accelerating. 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.

In the same way that ECU software optimises the way an engine performs, TVS’ gearbox (TCU) software does the same for the twin-clutch DSG (S-Tronic) unit.

The programme 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 DQ380/381 Stage 4 software can handle up to 850Nm of torque, when used with the mandatory TVS race clutch upgrade.

As with all TVS Tuning software, full customisation is available, allowing drivers to tailor their DSG (S-Tronic) performance for their preferred driving style. This simple plug-and-play setup can be installed by our comprehensive dealer network.

Please note: 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.
