Why TVS Engineering?

  • Decades of Expertise & DSG Specialisation: With nearly 20 years experience in DSG tuning, TVS is the globally recognised leader, leveraging cutting-edge technology to deliver peak performance for VAG vehicles worldwide.
  • ECU / TCU Synergy: Expertise with advanced ECU and TCU tuning optimises power delivery, torque handling, and shift precision. By creating seamless communication between engine and transmission, TVS ensures quicker acceleration, smoother shifts, enhanced driveability, and instant responsiveness.
  • Focused VAG Specialisation: TVS operates with a deep and narrow focus on Volkswagen and Audi Group vehicles, delivering high-quality solutions.
  • Exclusive Partnership with PERON: TVS and PERON Automotive maintain a close, collaborative partnership, ensuring UK & Irish customers benefit from expert knowledge, direct access to genuine TVS products, and seamless, personalised support for all tuning solutions.
  • Optimised Shift Performance: TVS customises shifting strategies based on driving modes (D, S, M), ensuring faster gear changes. Improved algorithms reduce delay in paddle shifts and upshift/downshift timings, providing both smooth daily driving and aggressive performance responses under load.
  • Increased Torque Capacity: The DQ500’s stock limit of 600 Nm is raised to support up to 1000 Nm through recalibrated torque limiters and enhanced clutch pressure. This allows high-output engines to operate without transmission slippage or premature wear.
  • Improved Clutch Cooling & Thermal Management: TVS tuning increases clutch oil flow, reducing heat buildup during high-stress driving. Enhanced thermomanagement ensures consistent gearbox operation within safe temperature limits, protecting the transmission from overheating.
  • Optimised Launch Control: Tailored launch control recalibrates the clutch and throttle engagement, improving take-off speed. TVS fine-tunes response times for quicker launches and enhanced acceleration, particularly useful in performance settings.
  • Extended Gearbox Life: By managing torque more efficiently and reducing clutch slip during shifts, TVS TCU tuning minimizes wear on critical components like clutches and flywheels. This results in longer-lasting, more reliable transmissions, especially in high-torque environments.
  • Perfect Engine and Transmission Synergy: TVS’s combined ECU and TCU tuning creates a flawless connection between the engine’s power output and the transmission’s shifting behaviour. This seamless interaction ensures that as the engine delivers more power, the transmission adjusts in real time for smooth, uninterrupted acceleration.
  • Tailored Power Delivery: By synchronising ECU and TCU, TVS can fine-tune engine performance to match the DSG’s capabilities. Whether you’re cruising or pushing your vehicle to its limits, the engine delivers power exactly when needed, while the transmission responds instantly with optimised gear shifts.
  • Torque Management & Precision: As the engine produces more torque, the TCU software raises torque limits and recalibrates clutch pressures. This ensures that the DSG gearbox can handle increased loads without slippage or excessive wear. The fine-tuned coordination between ECU and TCU makes sure torque is delivered efficiently, optimising acceleration and gear transitions.
  • Superior Launch Control: With combined tuning, launch control is precisely calibrated, allowing the engine and gearbox to work in harmony for quicker, more controlled take-offs. By perfectly timing clutch engagement and throttle response, the system maximises traction and acceleration, giving you the edge on both road and track.
  • Increased Longevity & Reliability: When both engine and transmission are tuned to work cohesively, there’s less stress on the drivetrain components. The reduction in gear slippage, clutch wear, and unnecessary engine strain leads to prolonged engine and gearbox life, especially in high-performance vehicles where stock tuning can often cause premature wear and tear.
  • Customised RPM Setpoints & Shifting Strategies: For performance drivers, TVS’s combined tuning allows for custom RPM setpoints, offering higher upshift RPM limits (up to 8000 RPM) and faster downshifts based on engine characteristics. This precise control ensures that the vehicle is always in the optimal gear for any driving condition, from track days to everyday use.
  • Optimised Powerband Utilisation: The ECU tuning ensures the engine operates within its optimal powerband, while the TCU adjusts shift points to keep the engine at peak performance. This results in more consistent and powerful acceleration, allowing you to fully exploit your vehicle’s potential without any hesitation or lag.
