TVS Engineering DSG Software – DQ380/381 (MQB)
Known issues that this software takes care of are poor shifting strategies, shifting at extremely low rpm’s, and slow reaction when accelerating.
With this single and affordable software package, we give you a solution to help your DSG have a longer lifetime and improved drivability.
TVS Drivability Upgrade: (comes with any stage 2+ and above software)
- Optimized D mode shift program for ultra smooth shifting
- Optimized S mode shift program for ultra smooth shifting
- De- or reactivation of the 1st gear (optional)
- Increased shifting speed
- Improved clutch cooling and thermal management
Examples Of Driveability Problems:
POOR GEAR SHIFTS: When entering a roundabout, the DSG has the wrong gear selected resulting in poor throttle response when accelerating. This is caused by a DSG shift program which is not matching the engine. TVS developed unique shifting strategies for any application.
UNDER REVVING: The DSG up-shifts at extremely low rpm’s. Generally, when you are driving 40-60 km/h the DSG runs already in its 6th gear at about 1100 RPM. When giving slight throttle the engine and gears start making audible vibration sounds. These sound will become more noticeable over time and will result in permanent flywheel damage. We can fix these problems by raising the shifting rpm’s. Our unique software also has protective capabilities to reduce the frequently occurring DSG problems which will result in damages to the clutches and gearbox.
SPORTS MODE: The majority of the drivers experience drivability problems in Sports mode. The down-shift rpm’s are often too low or sometimes too high. We fully customize the S mode so that it matches the engine power output and driver requirements.
MAXIMUM RPM: The maximum rpm is determined based on the power output of the engine to achieve the fastest performance while keeping drivability smooth. By doing this, the car accelerates faster and of course, the lifespan of the engine and turbo will last longer.
