The RacingLine OEM+ TCU Dynamic Software & Tuning is an essential upgrade to get the most out of any modified DSG or S-tronic car.
Several years of road and track development have given us the smartest transmission software on the market: by continually feeding the engine ECU’s torque demands through to the gearbox’s controller, the system dynamically calculates and adjusts the DSG’s variable clutch pressures to suit whatever your power output is.
Meaning that just one RacingLine TCU software upgrade will serve your car from standard, through Stage 1, right up to Stage 3 and beyond. So unlike some, there's no need for a new TCU calibration each time you increase your car’s performance.
What does TCU
DSG tuning do?
Our engineers reprogram the gearbox's calibration inside the TCU (Transmission Control Unit). This allows the transmission to maintain higher torque levels through our dynamic clutch pressure strategy, right up to a mighty 19 bar pressure. The result? Shifts are even faster, giving harder acceleration through the gears, whatever level of performance your car has - up to and beyond Stage 3.
Meanwhile, the driving mode strategy itself is optimised to suit higher power levels, giving a more natural gear selection profile. Flick the car over to manual, and at last you'll have true gear control at your fingertips - no auto-upshift*, no kick down until you command it (or drop back to D/S modes).
Not only that, launch control will get you off the line quicker through allowing more boost at launch and increased launch RPM, combined with a less intrusive traction control in launch mode.
* auto-upshift disable not available on certain gearbox codes
All tunes are tuned by us at Projex Euromotive, making a purchase of this tune gives you access to all stages for 1-3 depending on application (what stage for you will be determined on appointment day). After purchase an email will be sent out to you arranging a date and time of software installation.
