No, remapping a vehicle is not illegal in the United Kingdom.

We advise that you should inform your insurance company about any modifications you make to your vehicle.

Yes, every read we take is archived to secure storage.

Usually the process is complete within an hour, though occasionally at peak periods it can take slightly longer to receive the upgraded software back from our tuning panel, we therefore recommend that you allow at least 2-3 hours.

Technically Yes, modifying any part of your vehicle can invalidate some or all clauses of a manufacturer warranty, in almost all cases however we perform no physical modification to your ECU as the remap can be loaded via the diagnostic port.

Turbo diesel engines respond exceptionally well to remapping, you can usually expect to see a 20-30% gain in performance.

Turbo petrol engines respond very well to remapping, you can usually expect to see a 15-30% gain in performance.

Naturally aspirated engines do not respond quite as well to remapping as their turbo counterparts, realistically you can expect a 5-10% performance gain.

On pre-2001 cars, for the majority remapping involved unsoldering a chip from the ECU motherboard and either adding a socket or a new chip for the updated map data to be stored on, with advances in technology we no longer need to do this as most vehicles can have their software updated via the OBD2 port.
