What we do
JF Remapping is a mobile ECU remapping service: we come to you, at home or at work, and recalibrate engine software for cars, vans and pickups. Whether you want a car that pulls more willingly, a van that copes better with its load, or a vehicle that’s a little easier on fuel when driven gently, the work starts with the same thing: understanding your vehicle and how you use it.
How we work
Every enquiry begins with your registration and a conversation. We’ll ask about mileage, condition, any modifications and what you want from the vehicle, because those answers decide what’s sensible — and occasionally whether a remap is worth doing at all.
Before anything is changed, your vehicle’s original software is read and saved. You’ll have a clear price before any work is booked.
Where we work
Because the service is mobile, there’s no workshop to drive to. We visit customers across Cambridgeshire, Norfolk, Suffolk, Lincolnshire and Hertfordshire. See all areas covered to find your town.
