ECU Remapping & Diagnostics in Essex
Better response and, on many engines, better economy - plus proper fault diagnosis when the dashboard lights up.
An ECU remap rewrites the calibration in your engine management software - fuelling, boost, ignition timing and torque limiters - to suit the engine rather than a factory compromise. Gains vary a lot by engine, so we will tell you honestly what to expect before anything is touched.
Diagnostics is the other half of this service. Modern vehicles store fault codes for everything from a loose sensor to a failing injector. We read those codes, test the circuit or component, and tell you what is actually wrong rather than guessing and replacing parts.
Before any remap, tell your insurer - a modification should be declared. Removing a DPF from a road vehicle is illegal in the UK and an MOT failure, so for DPF, EGR and similar faults our work focuses on finding and fixing the real cause.

Questions
Will a remap affect my warranty or insurance?
It can. You should tell your insurer about any modification, and a manufacturer warranty may be affected, so check before you book.
Is ECU remapping legal?
Remapping is legal, but the vehicle must still meet its emissions standards at MOT, and removing a DPF from a road vehicle is illegal.
Can you diagnose faults at the roadside?
Yes. For many faults we can read and test on the spot and often get you moving without a tow.
Is my engine suitable for a remap?
It depends on the engine and its condition. We check the vehicle first and will tell you if a remap is not worthwhile.
