The detail

What Is ECU Remapping?

Every modern engine is controlled by an ECU, the small computer that decides how much fuel, boost and timing the engine gets. From the factory those settings are left deliberately conservative to cover different climates, fuel grades and service habits around the world. A remap rewrites that software so it is optimised for your engine and how you actually drive, here in the UK.

A Stage 1 remap is the safe, popular choice on a standard vehicle. Because we build the map from your car's own original file rather than a generic download, the power comes in smoothly and predictably, with typical gains of 25 to 35% more power and up to 15% better fuel economy when you drive the same way. It is all done at your home or workplace in around 60 to 90 minutes, and you only pay once you have driven the car and you are happy.

You Know There's
More In It.

A remap is not just for fast cars. These are the things drivers and tradespeople tell us before we tune their vehicle. A Stage 1 map fixes the cause, not just the symptom.

Sluggish Acceleration

The car takes too long to respond when you press the pedal, which makes overtakes and pulling out feel stressful.

Flat Spots In Power

Noticeable dips or hesitation in power delivery as you work through the rev range instead of smooth, linear pull.

Struggling When Towing

The vehicle feels underpowered and labours when pulling a caravan, trailer or a fully loaded van.

Poor Fuel Economy

Spending more than you should at the pump despite careful, steady driving on your usual routes.

Gearbox Hesitation

An automatic box holding gears too long or shifting roughly because torque is weak low down the range.

Lacking Mid Range Pull

Not enough punch where you actually drive, so you are forever changing down a gear just to keep up.

Questions

Remapping FAQs.

Is a remap safe for my engine?
We build the map from your original file and keep your power delivery smooth and within safe limits, then road test it before we leave.
Do I pay before or after?
After. You pay once you have driven the car and you are happy with it. If you are not happy, we reverse it free.
How long does it take?
Most remaps are done in 60 to 90 minutes, right there on your driveway or at your workplace.
What vehicles can you remap?
Diesels, petrols and vans across all the major makes. Send your reg and we will confirm.
Will it affect my warranty or MOT?
A remap does not change your emissions hardware, so it does not affect your MOT. We are happy to talk warranty through with you before booking.
How much power and MPG will I actually gain?
On a turbocharged diesel, a Stage 1 remap typically frees up around 20 to 35% more power and 25 to 40% more torque, with no hardware changes. Because the extra pull arrives lower in the rev range, many drivers also see roughly 5 to 15% better MPG on steady motorway runs when they drive the same way.
