FAQ
Frequently Asked Questions
What is ECU remapping?
ECU remapping is the process of modifying the software in your vehicle’s Engine Control Unit to optimise performance, fuel economy, or both. We safely adjust parameters such as fuel delivery, turbo boost pressure, and ignition timing to unlock your engine’s true potential while staying within safe operating limits.
How long does ECU remapping take?
Most ECU remapping services are completed within 1-2 hours at your location. This includes connecting our professional diagnostic equipment, reading the original ECU file, uploading the custom remap, and testing the vehicle to ensure everything runs perfectly.
Will remapping void my vehicle warranty?
ECU remapping can potentially affect your manufacturer’s warranty, depending on the terms and conditions. However, our remaps are fully reversible. We keep a backup of your original ECU file, so the vehicle can be returned to factory settings at any time if needed. Many customers wait until their warranty period ends before remapping.
Is ECU remapping safe for my engine?
Yes, when done professionally. We use genuine Alientech KESS3 equipment and custom-written software that stays within your engine’s safe operating parameters. Our remaps are designed to enhance performance while maintaining reliability and longevity. We have over 15 years of experience and have remapped over 840 vehicles without issues.
What’s the difference between Stage 1 and Stage 2 remapping?
Stage 1 remapping is designed for completely standard vehicles with no modifications. It optimises the existing hardware for better performance and efficiency. Stage 2 remapping is for vehicles with hardware upgrades (such as exhaust systems or upgraded turbochargers) and requires these modifications to be fitted first. We specialise in Stage 1 remaps for everyday vehicles.
How much power will I gain from a Stage 1 remap?
Power gains depend on your specific vehicle and engine type. Turbocharged petrol and diesel engines typically see gains of 20-40% in horsepower and 30-50% in torque. Naturally aspirated engines see more modest gains of 5-15%. We can provide specific figures for your vehicle model before proceeding.
Can ECU remapping improve fuel economy?
Yes! Our Eco Remap is specifically designed to improve fuel efficiency by up to 25%. Even our Balanced (50/50) and Power remaps often deliver better MPG because the engine works more efficiently. You’ll notice improved throttle response means less accelerator pedal input is needed, resulting in lower fuel consumption during normal driving.
Do you offer a warranty on your remapping service?
Yes, we stand behind our work. All our remaps come with a satisfaction guarantee, and we keep a backup of your original file. If you experience any issues directly related to the remap, we’ll work with you to resolve them. We also offer lifetime support for all remapped vehicles.
Can you remap any vehicle?
We can remap most modern petrol and diesel vehicles from 2000 onwards, including cars, vans, and small commercial vehicles. Our Alientech KESS3 equipment supports over 12,750 ECU types across all major manufacturers including Audi, BMW, Mercedes, Volkswagen, Ford, and many more. If you’re unsure about your vehicle, contact us and we’ll confirm compatibility.
What is DPF cleaning and when do I need it?
DPF (Diesel Particulate Filter) cleaning removes accumulated soot and ash from your diesel vehicle’s exhaust filter. You may need DPF cleaning if you experience warning lights, reduced performance, limp mode, poor fuel economy, or excessive smoke. Our mobile chemical flush cleaning service restores proper DPF function without expensive removal or replacement.

What is engine carbon cleaning?
Engine carbon cleaning removes harmful carbon deposits that build up inside your engine over time, particularly in the intake valves, injectors, and combustion chambers. These deposits reduce performance, fuel economy, and increase emissions. Our carbon cleaning service restores lost power, improves MPG, and helps your engine run smoother and more efficiently.
