What Is Engine Remapping?
Engine remapping involves recalibrating your vehicle’s ECU (Engine Control Unit) to optimise performance. By adjusting parameters such as:
- Fuel delivery
- Ignition timing
- Turbo boost pressure
- Throttle response
We can dramatically improve how your car drives. Whether it’s a diesel workhorse or a high-performance petrol engine, remapping can deliver:
- Increased horsepower and torque
- Improved fuel efficiency
- Smoother, more responsive driving
- Reduced turbo lag and better acceleration
BMW & Mercedes Remapping — Our Speciality
We’re not just generalists—we’re BMW and Mercedes group specialists. Our remapping services include:
- In-house ECU programming and coding
- Adaptation of new and used components
- Virginising used ECUs and gearboxes
- Digital service history updates
- Key programming for BMW and Mercedes vehicles
We often perform procedures that main dealers won’t or can’t, making us a cost-effective alternative for performance tuning and component adaptation.
EV Performance Optimisation
While traditional remapping applies to combustion engines, we also offer performance optimisation for electric vehicles (EVs). Our Level 3 and 4 EV-trained technicians can assess and fine-tune EV systems where applicable, including:
- Battery health and efficiency checks
- Regenerative braking calibration
- Drive mode optimisation
As EV technology evolves, we stay ahead—so your electric vehicle performs at its peak.
