Redefined Shift Points
Available with Unitronic Stage 2 and Stage 3 TCU Software, redefined shift points allow for improved drivability and performance in conjunction with Unitronic ECU Performance Software.

Increased Clutch Pressure
Clutch clamping pressure increased up to 600NM for the MK8 GTI and up to 700NM for the MK8 Golf R and 8Y S3 in order to meet the power demands of Unitronic ECU Performance Software.

Advanced Torque Management
Unitronic has calibrations available for limited torque and full torque levels when Launch Control (AMAX) is engaged. Limited (low) torque calibrations will limit torque in 1st gear, which is ideal and optimized for use on true street prepped car launching on an unprepped street-like surface with street tires with little to no drivetrain upgrades. Full torque calibrations will provide maximum torque for launching in ideal conditions like on a prepped/glued race track surface with drag radials or slicks and using drivetrain upgrades like a Dogbone Mount.

Gearbox Oil Pressure Raised
Increasing the oil pressure in the gearbox improves the overall gearbox functions, results in quicker reactions for clutch and gear change functions, reduces gearbox chatter when driving on rough road surfaces, and helps to ensure more stable clutch pressure.

Disabled Kickdown in Manual Mode
Disabling the kickdown in Manual mode gives you full control of gear selection without unexpected downshifts when you press the accelerator. This ensures the car holds the gear you choose, providing a more connected and predictable experience during spirited driving or track sessions.

Quicker Gear Shifts
Unitronic's TCU Performance Software calibration enhances the gear shift speeds making them up to 70% quicker.

Gear Display Enabled in D and S Mode
Gear Display is enabled, allowing the driver to see the current gear in both D- and S-mode on the Virtual Cockpit / MFD.(D1, D2, etc. & S1, S2, S3, etc.)

Speed Governor Removed
Vehicle speed limiter within ECU is removed. (Subject to transmission rotational speed limit.)

Dual Setpoint Adjustable Launch Control
Unitronic has adjusted the launch control RPM setpoints to allow for quicker acceleration off the launch control. Dual-stage launch control allows users to choose between two different launch control RPM setpoints based on the current conditions observed. (surface conditions, tires, etc.) Launch Control Setpoint 1 is activated at 100% pedal position, without engaging the kick-down switch. Launch Control Setpoint 2 is activated at "110%" pedal position. (100% pedal position with the kick-down switch engaged) Additional launch control customization is available via Unitronic's FeatureBox and UAF suite.

Increased rev limiter / max upshifts
Meant for larger turbos and higher horsepower setups that make power higher in the rev range, Unitronic Stage 3 TCU Software also raises the maximum engine speed rev limit accordingly. Must be combined with Unitronic Stage 3 ECU tune or other tunes which make the necessary adjustments on the ECU side.

Improved Torque Reduction
Stage 3 TCU Software refines how torque is managed during shifts, reducing torque intervention for faster and smoother high-power gear changes.

Sailing Mode Disabled (EU/RoW only)
Disabling Sailing Mode keeps the drivetrain fully engaged instead of engaging virtual neutral and free-wheeling when coasting in certain drive modes at speeds between 55kph/35mph and 160kph/99mph. This provides the driver with a more engaged performance orientated feeling and driving experience. Sailing mode is inactive on most North American vehicles from the manufacturer.

TCU Tuning Without Barriers

Unitronic continues its mission of removing tuning barriers and making high-performance software upgrades more accessible than ever. With a straightforward unlock process, seamless integration within UniCONNECT+ and UniPRO+ applications, and no-cost TCU Unlocks, enthusiasts can now experience all the potential of their vehicles, without necessary dealer visits or expensive third-party tools or unlocking services. End-users, when equipped with Unitronic’s DSG Bench Harness, can unlock their TCU from the comfort of their own home or garage!
