ECU remapping in London

We check your engine, ECU and setup before fitting a matched tune at your home or workplace.

What is remapping?

A remap changes the calibration in your engine control unit (ECU). It adjusts how the engine delivers power, torque or fuel economy, depending on the tune.

We fit a pre-developed file matched to your engine and ECU. Before fitting, we check the vehicle and whether the file suits your setup.

Mobile fitting at home or work

We read the ECU, apply the matched file and check the vehicle afterwards. Tell us about existing faults or modifications before we arrive.

Remapping FAQs

Before you book, check how a remap can affect insurance and the MOT or browse all remapping guides.

What is a Stage 1 ECU remap?

A Stage 1 remap changes the engine software on a suitable car with standard hardware. A performance map can change how the engine delivers power and torque, as well as how it responds to the throttle.

What’s the difference between Stage 1 and Stage 2?

Stage 1 is intended for suitable standard vehicles. Stage 2 is calibrated for specific hardware upgrades, which vary by engine. Tell us what’s already fitted so we can check compatibility. If the car is under warranty, check the provider’s terms before booking.

Which tune suits my car?

Start with the vehicle finder. The options depend on your exact engine, ECU and setup. Include any existing modifications in your enquiry and tell us whether you’re looking for performance or fuel economy.

How much power and torque could my car gain?

It depends on the exact engine, its condition and the calibration it can run. Send us your vehicle details so we can discuss what’s realistic for your setup.

Is a remap safe for my engine?

We check the vehicle and match the calibration to the engine and ECU before fitting. Tell us about warning lights, poor running or known faults. Those may need diagnosing and fixing before the car is suitable for a remap. See what we consider on a high-mileage car.

Will a remap improve my fuel economy?

Stage 1 Eco is designed with fuel economy in mind. Your actual fuel use depends on the car, your routes and how you drive. Using more of the available power can increase fuel consumption.

Do I need a rolling road for a mobile remap?

We fit a pre-developed calibration matched to your engine and ECU at your home or workplace. A rolling road, also called a dyno, is used to measure power and torque and can be used during calibration development.

What petrol grade should I use after a remap?

Use the fuel grade specified for your vehicle and the calibration fitted. Some petrol maps are designed for a higher minimum octane. Ask us what your tune requires before fitting.

Can the remap be removed?

Returning the ECU to its factory calibration depends on the ECU and whether the correct original software is available. Ask us about the options for your car and the cost before booking. Read about returning to stock or reinstalling after a dealer update.

Can you remap my car at home or work?

Yes. We offer mobile fitting across Greater London and check selected postcodes just north of London. Send your postcode and let us know where the vehicle will be parked. See our London coverage.

What do I need on the day?

Park somewhere safe with room to work around the vehicle and have the keys ready. Tell us about gates, permits or other access restrictions when you book.
