A professional ECU remap adjusts the engine management software to improve power, torque, or fuel economy — or a balance of all three. At JLR Autocare every remap starts with a diagnostic health check: there is no point tuning an engine with an underlying fault, and we will tell you if your vehicle is not a good candidate.
Economy remaps are popular with high-mileage drivers and can reduce fuel consumption in normal driving. Performance remaps release the headroom manufacturers leave in the engine, with the biggest gains on turbocharged petrol and diesel engines. For vehicles used for towing, a torque-focused remap makes a noticeable difference to how easily the car pulls a caravan or trailer.

Frequently asked questions
Will a remap affect my insurance?
A remap is a modification and you must declare it to your insurer. Most insurers accept remaps with little or no premium change, but you should check first.
Can the original software be put back?
Yes. We save your vehicle's original software before any change and can restore it at any time.
Is remapping safe for my engine?
We health-check the engine first and stay within the headroom the manufacturer leaves in the design. A vehicle with an existing fault or heavy wear is not tuned until that is put right.
