Frequently Asked Questions (FAQs)

1. What is ECU remapping?

ECU remapping is the process of recalibrating the software inside your engine’s control unit. By fine-tuning parameters such as fuel delivery, ignition timing, and boost pressure, we can safely unlock extra performance, improve throttle response, and in some cases reduce fuel consumption. Every remap we provide is based on tested, proven files — not guesswork.

2. Do I really need a remap?

Almost every vehicle can benefit from a remap. Vehicle have become an essential part of daily life and business operations, so why not make yours work smarter for you? A remap can transform the driving experience by improving performance, responsiveness, and even fuel efficiency. With fuel prices constantly on the rise, the savings alone could help the remap pay for itself over time—making it both an upgrade and an investment. From the factory, the ECU map is a safe, global compromise. A remap narrows the focus to your environment, your fuel quality, and your needs — which is why it can safely deliver more MPG and or power without harming reliability when done properly.

3. Will remapping damage my engine?

Not when done properly. We only use software that has been tried and verified, and before any tuning we run a full diagnostic check to make sure your engine is in good health. If we spot issues that could make tuning unsafe, we’ll tell you upfront rather than risking your car. Consideration will also be made to higher mileage vehicles. 

4. What gains can I expect?

It varies by make and model. A typical Stage 1 remap delivers a strong increase in power and torque while keeping everything within safe limits. Economy-focused calibrations can also reduce fuel use by up to ~15% depending on driving style. Gains are also influenced by the general health and age of your vehicle too for example we wouldn’t push a 100,000 mile car as hard as we would a 50,000 mile car. If you have more questions contact us we’d be more than happy to give you some advice.

5. What’s the difference between Stages?

• Stage 1: A software-only recalibration of the ECU that stays within the limits of the factory hardware. 

• Stage 2: A more aggressive ECU calibration designed to take advantage of hardware upgrades usually those that improve airflow (exhaust/ intake).

• Stage X: Anything past Stage 2 grade modifications. Dynamometer Required.

6. Do I need to tell my insurance company?

Yes. ECU remapping is classed as a performance modification, and most insurers require disclosure. Failing to do so can invalidate your policy.

7. Can the remap be removed?

Yes. We back up your original ECU file before touching anything. If you ever want to revert to factory settings. 

8. Will remapping affect my MOT or emissions?

Our performance and economy remaps are designed to work with all standard emissions systems intact. If you ask for emissions system removal (e.g. DPF/EGR/AdBlue), we will advise you that this is not road-legal and could cause MOT failure.

9. How long does the process take?

Most vehicles can be tuned within 1–2 hours, including diagnostics, back-ups, and road testing. More complex jobs (Stage 2, troubleshooting, or custom hardware setups) can take longer.

10. Is there a warranty or guarantee?

Yes. All remaps are covered for a lifetime software warranty. We guarantee that all our remaps are based on proven, tested files.

11. What happens if something goes wrong after a remap? 

If you experience an issue after remapping, contact us straight away, because we keep your original ECU file, we can always restore it as a last resort. In most cases, issues are unrelated to the remap but we’ll help you diagnose and resolve them fairly.

12. Why the price?

Our pricing reflects the quality of the service we provide. We use specialist tools (not cheap clones), work with reputable, dyno-tested files, and deliver the convenience of a mobile service that comes to you. All work is carried out by trained technicians — you’re not being used as a test subject or learning experience. Everyone knows you often get what you pay for.

13. How do we come up with a quote?

ECUs and TCUs aren’t all the same — some manufacturers use stronger protections, others are easier to access. When we prepare a quote we assess the level of defence in place, and the time and tools needed to complete the work.
