Everything You Need to Know About Our Services
At Southwest Remapping, we provide specialist ECU tuning and engine remapping solutions designed to unlock the best from your vehicle. Whether you’re seeking improved fuel economy for daily driving, sharper throttle response for a sportier feel, or maximum power for performance applications, our expert team delivers results you can trust.
ECU remapping involves reprogramming your vehicle’s Engine Control Unit (ECU) to optimise performance. By adjusting parameters such as fuel injection, turbo boost, and ignition timing, we can unlock more power, torque, and efficiency.
It depends on the type of tune. Our Economy Tune is specifically designed to improve fuel consumption, especially for fleet or high-mileage drivers. Performance tunes may slightly reduce economy due to increased power.
Yes. We use data-driven, tested software and tools to ensure your remap stays within safe limits of your vehicle's mechanical components. Our team always prioritises long-term reliability.
Absolutely! We offer a mobile remapping service throughout Plymouth and the South West, so we can tune your vehicle at home, at work, or on-site for convenience.
It’s possible that a remap could void a manufacturer’s warranty. We recommend checking with your vehicle provider. However, our remaps are undetectable to most diagnostic tools and can be reversed if necessary.
Typically, a remap takes between 1 to 2 hours, depending on your vehicle and the service chosen. We'll confirm estimated time during your booking.
We remap a wide range of vehicles including cars, vans, 4x4s, trucks, agricultural machinery, and motorcycles. If you're unsure, just give us a call.
A Stage 1 Tune is a software-only upgrade that enhances power and torque without needing hardware modifications. It’s safe for standard vehicles in good condition.
