Use the filters below to see the power and economy figures available on your exact vehicle. No obligation, just the numbers.
Release what your engine already has in it
Manufacturers set engines up cautiously at the factory to cope with different fuel grades, driving styles and markets around the world. A remap retunes those settings around your vehicle and the way you actually drive it.
The figures behind the work
Your engine is controlled by software stored in its ECU. From the factory, that software is set conservatively to suit every market, climate, and fuel quality the manufacturer sells into. A remap adjusts those settings to release performance and efficiency the engine is already capable of, safely and within sensible limits.
Done well, a remap can give you more power and torque, better fuel economy, and sharper throttle response. Economy remaps are particularly popular with diesel drivers and van fleets looking to cut running costs. The key words are done well. The quality of a remap depends entirely on the knowledge behind it.
Why CR Auto Engineering
Plenty of companies offer remapping. What sets CR apart is the depth of engineering behind it. We are not only remappers, we are engine specialists, so we understand the mechanics of what we are tuning, not just the software.
At CR Auto Engineering, every remap is carried out by people with decades of engine reconditioning experience. We know diesel engines, petrol engines, injectors, and cylinder heads. That knowledge shapes how we approach every remap, and it means we can spot when a vehicle needs attention before a remap rather than after.
We do not just tune engines. We rebuild them. That is the difference.
What sets us apart:
- Viezu approved and insurance backed
- Decades of engine expertise
- Workshop or mobile at your home or work
- Cars, vans and commercials
We come to you, or you come to us
Two ways to get your vehicle remapped, both to the same standard. Pick whichever is easier for you.
Bring your vehicle to our Aston workshop. This is the one to choose if you want a pre-remap health check included, if there are any existing faults worth looking at first, or if you simply want the job done in a full workshop by people with the equipment and experience behind them.
We come to you, at home or at work, whenever suits. Our mobile service is ideal for straightforward remaps on vehicles in good health. We cover Birmingham and the wider West Midlands, including Solihull, Wolverhampton, Walsall and Dudley.
Had my diesel Transit remapped and the difference is night and day. Pulls much better when loaded and I’m getting noticeably more to the tank. These guys know engines properly.

Remapping questions, answered
The things drivers most often ask before booking a remap. If your question is not here, just call us.
It should be declared, yes. Most mainstream insurers accept a Stage 1 remap, though a few add a small premium. Since a non-declared modification can affect a future claim, it is worth a quick call to your insurer before you book.
Done by people who understand the engine, yes. We run a health check before we start to confirm the vehicle is in good shape, work within safe limits for your specific engine, and keep your original file so you can go back to standard whenever you want.
Most are done within an hour or two. We will give you a realistic time when you enquire, based on your vehicle and whether you are coming to the workshop or booking a mobile visit.
Yes. We keep your original ECU file and can put the vehicle back to its factory settings any time you ask.
For many diesel vehicles, an economy remap can reduce fuel use, especially on longer or motorway driving. Results vary by vehicle and driving style.
Yes. Vans and light commercials are a big part of what we do, and economy remaps are popular with drivers and small fleets watching their fuel costs. Send your details and we will confirm suitability.
Yes. Alongside the Aston workshop we run a mobile service across Birmingham and the West Midlands, coming to your home or workplace at a time that suits. Tell us where you are and we will confirm availability.
Our workshop is in Aston, Birmingham, easy to reach from across the West Midlands including Solihull, Wolverhampton, Walsall, Dudley and Coventry.
