What is ECU remapping?
Every modern engine is run by a computer, the ECU, which decides how much fuel to inject, when to fire the spark and how hard the turbo works. Manufacturers set those values cautiously so one engine suits every climate and every driver.
A remap rewrites those stored settings for your exact engine. It is a software change, so nothing is added to the car, and the original software is saved so it can be restored.

Common questions about remapping
Short answers. The guides go into more detail.
What is ECU remapping?
It is a software update to your engine control unit that re-calibrates fuelling, ignition and boost for your exact engine, so it delivers more of its potential. Nothing new is fitted for a stage 1 remap.
Is it safe for my engine?
A remap written for your engine, kept within safe limits and tested on a dyno, works within what the engine was designed to handle. A healthy, serviced engine gives the best and safest result.
Will it affect my insurance or warranty?
You should tell your insurer about a remap, and check your manufacturer warranty terms before you book. Our guide explains both.
Can a remap be reversed?
Yes. The original software is saved before any change, so it can be restored.
How much power will my car gain?
It depends on the engine. Search your vehicle to see the standard and remapped figures for your exact engine.
Do you remove DPF or EGR systems?
No. Removal is illegal on road vehicles. We offer diagnosis, cleaning and repair of DPF and EGR faults instead.
