BMW ECU & Gearbox Remapping in North Somerset & South Wales
MTechTuning specialises in professional ECU and gearbox remapping for BMW vehicles, delivering improved performance, drivability and efficiency while maintaining reliability. We provide a fully mobile BMW tuning service across North Somerset and South Wales, carrying out all work at your home or workplace.
Specialist BMW Tuning Using Dealer-Level Diagnostics
BMW vehicles are engineered with performance in mind, but factory software often limits their full potential. Our BMW ECU and gearbox remaps are carefully calibrated to improve throttle response, torque delivery and overall drivability without compromising long-term reliability.
All BMW tuning work is carried out using dealer-level diagnostics, with full vehicle health checks completed before and after tuning. This ensures all systems are operating correctly and allows us to tailor the software specifically to your vehicle.
BMW ECU & Gearbox Remapping
For the best results, BMW ECU remapping can be paired with gearbox remapping to ensure the engine and transmission work together seamlessly. This can result in smoother gear changes, improved shift behaviour and better use of the increased torque.
BMW Models We Commonly Tune:
• BMW 1 Series, 2 Series, 3 Series and 4 Series
• BMW 5 Series and 6 Series
• BMW X Series models
• BMW M Performance models
• Petrol and diesel BMW engines
