DSG & Auto Gearbox Remapping
What can be improved?
Torque Limits
A common limitation of automatic gearboxes is the software-imposed torque cap, which prevents tuned engines from delivering their full potential, even if the engine is capable of producing more power. A common workaround is to “fool” the gearbox control unit (TCU) into thinking the torque is lower, but this approach is not ideal for high-performance vehicles that demand precise power delivery and maximum control.
At Autotech Tuning, we can raise or remove the torque cap on many automatic gearboxes, allowing your engine to achieve full horsepower and torque gains while maintaining safe and reliable gearbox performance.
Forced Up Shift
Some drivers find the automatic gear shifting in manual mode frustrating, as forced upshifts can interfere with their preferred driving style and reduce control over the vehicle. At Autotech Tuning, we can adjust or disable automatic upshifts on many performance cars, giving drivers full control over gear changes. This adjustment can significantly enhance driving enjoyment, acceleration, and performance, especially on fast roads and race tracks.
Launch Control
For the perfect launch off the line, we can optimise your car’s launch control system to maintain a specific RPM limit while stationary. This ensures the ideal balance of power and grip, delivering a fast, smooth start with minimal wheel spin. Perfect for track days, performance driving, and high-powered vehicles, this adjustment maximises your car’s acceleration and launch performance.
Types of DSG/DCT Transmissions
A Direct-Shift Gearbox (DSG) is an advanced type of automatic gearbox that uses two clutches and two sets of gears to change gears quickly and smoothly. Unlike traditional automatic gearboxes, a DSG does not use a torque converter, which improves efficiency. Instead, it relies on an electronic system that predicts the next gear based on driving conditions and pre-selects it for faster shifting.
DSG gearboxes can be operated manually using paddle shifters or a selector lever, or they can run fully automatically.
DSG and DCT Terminology
The term DSG is used by the Volkswagen and Audi Group to describe their Dual-Clutch Transmission (DCT) systems. While other manufacturers use different names for their DCTs, the performance benefits are largely the same: faster gear changes, smoother power delivery, and improved efficiency.
History and Models
DSG gearboxes were first used in Porsche racing cars in the 1980s and were introduced to the public in 2003 with the Volkswagen Golf R32 and Audi TT 3.2. Since then, DSGs have been incorporated into many Volkswagen Group models, including Skoda and SEAT, with Audi often branding them as S-Tronic.
Common DSG versions include:
Six-speed wet-clutch DSG (DQ250): Handles higher torque and suits high-performance engines.
Seven-speed dry-clutch DSG (DQ200): Lighter, more fuel-efficient, but less durable.
ECU Remapping and Performance Gains
When we remap an ECU, we first read the original file that controls the engine’s “maps” — parameters like ignition timing, fuel pressure, torque settings, and boost pressure. Our expert file team then adjusts these maps to unlock lost power and, in many cases, improve fuel economy.
