We explain what is suitable for your vehicle, and what is not, before you commit.
Every modern vehicle is controlled by an engine control unit (ECU): a small computer that decides how much fuel to inject, when to ignite it, how much boost a turbo should make and much more. Manufacturers program the ECU to suit a wide range of markets, fuel qualities and driving styles, so the factory calibration is often a compromise rather than the best fit for your vehicle and the way you use it.
Remapping means carefully adjusting that software calibration. Depending on the vehicle and what you want from it, a remap can be aimed at stronger, smoother performance, or at relaxed and efficient everyday running. Because every engine, gearbox and service history is different, we never apply a one-size-fits-all file without first understanding the vehicle in front of us.
Tuning a vehicle that already has a fault only hides the problem or makes it worse. That is why we check your vehicle's electronic systems before any work is agreed: we read stored fault codes, look at live data from the engine and its sensors, and record the results against your vehicle so you can see them too.
If the check shows something that should be fixed first, we will tell you plainly. If the vehicle is not suitable for the work you had in mind, we will explain why and suggest alternatives, before you commit to anything.
A warning light on the dashboard is a starting point, not a diagnosis. A fault code tells you which system or circuit is behaving outside its expected range, but not necessarily which part has failed. Our fault finding works methodically from the code to the cause, so you are not paying to replace parts on guesswork.
You can also look up what a code means in our free fault-code reference library, which explains P, B, C and U codes in plain English, with likely causes and what to check next.

A remap changes how the engine management software controls the engine, so it has to be done with care and only on a vehicle in good health. That is why we carry out a diagnostic check first and only recommend work we believe is suitable for your vehicle and its condition.
Any figures we quote are a guide only and never a guarantee. Results depend on the vehicle, its condition, age, mileage, specification, fuel and how it is driven. We will discuss realistic expectations for your specific vehicle before any work starts.
Yes. A remap is a modification, and most insurers require you to declare modifications. We recommend speaking to your insurer before booking so you know how it affects your policy.
Some ECU options remove or alter emissions-control systems such as DPF, EGR or AdBlue, and these can make a vehicle fail its MOT or be illegal to use on the road. It is your responsibility to keep your vehicle road legal, and we are happy to explain which options are and are not suitable for road use before you book.
We connect to your vehicle, read any stored fault codes, review live data from the engine and its sensors, and record the results against your vehicle record. You get a clear explanation of what we found and what we recommend next.
No. The online booking form sends us a request only. Our team contacts you to confirm suitability, price and a time, and nothing is booked or charged until that is agreed with you directly.
It depends on the vehicle and the work agreed. We give you an estimate when we confirm your booking, and we allow enough time for the diagnostic check so it is never rushed.
