Unitronic Stage 2 TCU Performance Transmission Tune For VW MK8 GTI/R / 8Y Audi S3

DSG Software Precisely Engineered to run combined with Unitronic Stage 2 Software or Stage 1/1+ Software if redefined D-Mode shift points are desired. At the moment, only DQ381.2 gearboxes with BLvXXXX0301 are currently tuneable through the OBD2 port with support for the newer TCUs with BLvXXXX0401 in the works. If you have a vehicle with the latter TCU, Unitronic offers multiple ECU calibrations suitable for safe use with the stock TCU calibration in a limited torque format.

Unitronic also offers an Unlocked DQ381 TCU Upgrade which allows customers with previously locked TCUs to finally tune their transmissions for maximum power.

Performance Software for your TCU Box Code is subject to availability

Features

• End-User Programmable with UniCONNECT+
  Flash your TCU from the comfort of your own home or garage. Within minutes (approximately 70-seconds to be exact on this platform), you'll be enjoying an entirely transformed driving experience.
   
• Redefined D-Mode Shift Points
  D-mode is optimized for improved performance with Unitronic Stage 2 ECU Software while avoiding the tendency to target quick upshifts to higher gears. Can also be used with Unitronic Stage 1/1+ Software if redefined D-Mode shift points are desired.
   
• Increased Clutch Pressure
  Clutch clamping pressure increased to 700NM in order to meet the power demands of Unitronic ECU calibrations.
   
• 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.
   
• 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.
