DSG/TCU Tuning

DSG/TCU Tuning

The DSG has a Transmission Control Unit similar to the Engine Control Unit that controls the operation of the transmission. The TCU and ECU talk to each to ensure the correct gear is selected under the current driving conditions and certain outputs like actual engine torque are cross referenced between the TCU and ECU to keep the system in check.

Its well established that the ECU Tune is the first part carried out in increasing engine performance however there comes a point where the TCU’s internal torque limit is reached at which point the ECU intervenes and safety measures are put in place to reduce torque, typically boost is limited amongst other parameters.

One of the primary functions of a DSG/TCU tune is to allow more torque to be transferred through the Engine and Transmission which results in more power and torque throughout the entire rev range (depending on vehicle model), there is also many other functions that can be modified to improve the overall driving experience.

Below is an example of how a DSG tune hugely improved midrange power and torque in a DSG VW Scirocco R. Results vary from model to model.

We offer 3 different TCU/DSG calibrations with some additional options to accommodate individual requirements.

Stage 1 DSG Tune

This DSG tune is suitable for most Stage 1 and Stage 2 ECU Tunes. Whilst its not essential we do recommended it for Stage 2 ECU tunes. Suited for people who don’t have any issues with the gearshift points.

• Torque limits increase matched to ECU outputs
• Increased maximum RPM limit/shift point
• Faster gear shift times

Stage 2 DSG Tune

This DSG tune is suitable for most Stage 1 and Stage 2 ECU Tunes. Whilst its not essential we do recommended it for Stage 2 ECU tunes. Suited for people who would like the gear changes a little more aggressive (not changing up so quickly)

• Torque limits increase matched to ECU outputs
• Increased maximum RPM limit/shift point
• Faster gear shift times
• Optimized gearshift RPM points in Drive and Sport mode(for example, doesn’t change to into 6^th at 50km/h, we make drive mode more driveable like you were driving a manual transmission whilst cruising. Sport mode sometimes feels like it never changes gears so we actually reduce the point at where it shifts to make it more driver friendly)
• Customized launch control – 3600,3800,4000,4200,4400,4600rpm

Stage 3 DSG Tune

This DSG tune is best suited for vehicles with a Stage 2/2.5/3 tune pushing torque higher than regular Stage 2 levels however is recommended at any stage. We will advise if this is best for your vehicle.

• Torque limits increase matched to ECU outputs
• Increased maximum RPM limit/shift point
• Faster gear shift times
• Optimized gearshift RPM points in Drive and Sport mode(for example, doesn’t change to into 6^th at 50km/h, we make drive mode more driveable like you were driving a manual transmission whilst cruising. Sport mode sometimes feels like it never changes gears so we actually reduce the point at where it shifts to make it more driver friendly)
• Customized launch control – 3600,3800,4000,4200,4400,4600rpm & also 3 step Launch option (launch from 3 preset RPM points which is determined by pedal position upon launch.
• Increased clutch clamping pressure. Up to 18 bar depending on torque output. Prevents clutch slip and improves clutch longevity
