Audi Diesel Tuning – What is ECU Remapping?

The engine control unit (ECU) in your Audi diesel is pre-programmed by the manufacturer with conservative settings to account for varying fuel quality and environmental conditions worldwide. ECU remapping optimises the engine software to unlock more power, torque, and fuel efficiency while maintaining reliability.

Increased Power & Torque – More responsive acceleration and stronger midrange power
Better Fuel Economy – Improved efficiency, particularly for motorway driving
Smoother Power Delivery – Reduced turbo lag and enhanced drivability
Optimised Gearbox Software – Faster shifts, improved throttle response (for automatic & DSG gearboxes)

At Onyx Performance, our custom remaps are developed in-house and tested on our 4WD Dyno, ensuring accurate, proven performance gains.
