Engine Control Unit (ECU) remapping or chip remapping as it is otherwise known is a process whereby your vehicle’s engine performance is fine-tuned to provide greater power and torque. Furthermore, ECU remapping increases your fuel economy and engine responsiveness. The process usually takes between 60-90 minutes, during which time there are no changes made to your vehicle’s hardware in actuality.
Things to Consider
If you are considering ECU remapping, you should be aware of the fact that resale value may be affected by carrying out this process. As well as that possibility, there remains a small risk that your engine could incur damage from improper remapping, creating excess heat in the vehicle and an increase in wear and maintenance requirements. Ultimately, it is imperative to consider whether the benefits outweigh the risks. As with most things, if you take your vehicle to an experienced professional, the risks will be significantly reduced.
How does it Work?
ECU remapping works based on the principle that, during manufacture, vehicles are tuned to a standard with a wide-range tolerance that can then be recalibrated to be more accurate. Factors such as temperature, fuel delivery rate and engine load can now be precisely managed, resulting in a vehicle that has a reduced margin of error and is significantly improved and precise. The process is fairly complex, but the increase in performance can be considerable for both turbo and non-turbo engines- up to an increase of 50% torque and 30% brake horsepower (bhp).
After having your vehicle’s chip remapped, you will be restricted to the use of high-performance fuels and you will need to have your vehicle serviced more frequently. As well as that, it is essential that you will be prepared to replace components as they wear out, as remapping does slightly increase the amount of strain on your vehicle due to high performance.
What’s the Cost?
The typical cost of remapping will be in the region of £200-£500 depending on the level of power you choose. There is also the option to have multiple maps, or switchable maps available for selection dependent on your needs. For example, you could have a ‘sport’ map or a ‘valet’ map. Although this costs more on the outset, in the long term it avoids the problem of having to run a high power map throughout the day when you don’t necessarily need it.
