What can be improved
Torque Limits – Unlock Full Power With ECU Tuning
Many automatic gearboxes have a factory-set torque limit programmed into the TCU, restricting how much power your engine can deliver—even after an ECU remap. This torque cap often prevents tuned engines from achieving their true performance potential. Some tuners attempt to “fool” the TCU by manipulating torque values, but this method is unsuitable for high-performance cars such as Jaguar XF, Jaguar XFR, F-Type, Range Rover, and 5.0 Supercharged engines, where precision power delivery is essential.
At Autotech Tuning, we professionally raise or completely remove the torque limiter on many automatic gearboxes.
This allows your vehicle to access full horsepower and torque gains from your ECU tuning, Stage 1 remap, Stage 2 remap, or custom performance software—while keeping gearbox operation safe, smooth, and reliable.
Forced Up Shift – Full Control With Performance Remapping
Factory settings often force an upshift in manual mode, limiting driver control and reducing engagement on fast roads or track days. This is especially common on performance cars like the Jaguar F-Type, Range Rover TDV6, and other tuned vehicles.
Autotech Tuning can disable or adjust forced upshifts, giving you genuine manual control over gear changes. With this software enhancement, your vehicle delivers improved acceleration, responsiveness, and a more connected driving experience—perfect for enthusiasts and drivers of remapped high-performance cars.
Launch Control – Maximum Acceleration With Precision Tuning
For the ultimate start, we can optimise your launch control system to hold the ideal RPM limit when stationary. This provides the perfect balance of power, traction, and grip, enabling rapid and consistent launches with minimal wheel spin.
Whether you drive a remapped Jaguar F-Type, a 5.0 Supercharged Range Rover, or any other high-powered performance vehicle, our launch control calibration ensures sharper acceleration and improved off-the-line performance—ideal for track days, performance driving, and ECU-tuned vehicles.
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.
