Remapping, done with an engineer's care

Careful, considered ECU remapping for prestige and performance vehicles across Warwickshire, by an engineer with 38 years' experience.

Remapping

More from your car — without compromising the car.

A remap should make your vehicle feel like it always should have, not push it past what it was built for. With an engineering background and a lifetime around high-performance vehicles, I take a measured approach to tuning: the right map for the car, the driver and how you actually use it — never a reckless chase for headline numbers.

If you want your car to pull more smoothly, respond more sharply or run more efficiently, let's have an honest conversation about what's realistic and worthwhile for your specific vehicle.

  • 01

    Forced-induction petrol

    Turbocharged and supercharged petrols typically respond with up to around 25% more power and noticeably sharper throttle. The big shift is in drivability — the car feels properly awake, not just faster on paper.

  • 02

    Turbo diesel

    Up to roughly 30% more power and a significant lift in torque, with most owners reporting better fuel economy on a steady run. Towing, motorway cruising and overtakes all change for the better.

  • 03

    Naturally aspirated

    Around 10–15% on most NA petrols. Less dramatic on paper than a turbo car, but a cleaner throttle response and a better top-end — especially on older performance engines.

  • 04

    Inside the engine's limits, every time

    Every map I write respects MOT emissions, the engine's design ceilings and the transmission behind it. Healthy gains, not headline gains — because the car still has to start every morning for the next ten years.

Why have me write the map

Remapping since the early '90s — back when you had to read the binary.

I started on Bosch Motronic ECUs — early Porsches and BMWs — in the early 1990s, before off-the-shelf files existed. That background still shapes the way I work: every car is health-checked first, the original file is read and saved, and the map is written for the specific vehicle, fuel and use case in front of me.

Cars are tuned at your home or workplace within roughly 25 miles of Kenilworth, with no travel charge. The work takes a couple of hours on the drive, and you keep the original file in case you ever want it back exactly as it was.

If your car isn't a good candidate — high mileage with known weak points, an overdue service, a tired clutch — I'll tell you before we start. We fit to a standard, not a price, and that applies to maps too.

Questions

Good to know

How much power will I actually gain?
On forced-induction petrols, up to around 25%. On turbo diesels, up to around 30%, with a useful bump in torque. On naturally aspirated engines, roughly 10–15%. Real-world figures depend on the specific car, its condition and the fuel it's running on.
Will it damage the engine or gearbox?
Not when the map is written sensibly. I stay inside the engine's design limits and the torque the transmission was built for — healthy gains, not headline gains. The car still has to start every morning.
Will it pass an MOT?
Yes. Every map I write respects MOT emissions standards. If a car is genuinely on the edge for emissions before I touch it, I'll tell you.
Can I have it taken back to standard?
Yes. I always read and save the original file before any work, so the car can be returned exactly to factory specification if you sell it or change your mind.
Will it improve fuel economy?
Often, especially on turbo diesels driven steadily — more torque lower down usually means less throttle for the same job. Driven harder, the gains turn into pace instead of mpg. That's your choice on the day.
How long does it take and where do you do it?
Usually a couple of hours on your driveway or at your workplace, anywhere within roughly 25 miles of Kenilworth. You don't have to take the car anywhere.
