Unlock the full potential of your DQ381 Gearbox in the MQB platform vehicles with RacingLine's TCU software. Designed to dynamically adjust to the demand.

We recommend TCU software at the start of any mapping journey, not just to handle the increased torque load from higher stages of power, but to improve the everyday drivability you experience.

This product listing is for software only, please ensure your vehicle is error free with no running issues before purchasing and installing TCU Software.

Key Features

• Dynamic Control, continuously adapting clamping pressure and eliminating the need for fixed-stage tuning
• Increased RPM limits, allowing the engine to reach full potential before shifting
• Refined shift strategies for smoother daily driving and sharper power delivery
• Increased clamping pressure, calibrated to handle greater torque demands without slip
• Higher torque limits, preventing the ECU from unnecessarily restricting power output

PDM / Home Installation Features

• Allowing for installation wherever you are, no need to visit our workshop (Unless you want to)
  
• Perfect for pairing with ECU Software, allowing you to switch between mapping profiles and anti-theft mode
