Frequently asked questions

What is Diesel Engine Remapping?

Diesel engine remapping means changing your car's air/fuel mixture and quantity to unlock more power and economy without major mechanical changes, such as performance exhausts.

Do Diesel Engine Tuning chips work?

Yes. All engines are built to operate within the limits of their abilities, for example to cope with poor quality fuel or high-altitudes. A diesel tuning chip simply alters the engine's air/fuel mixture and quantity settings to unlock additional power and economy for regular European driving.

Does Diesel Engine Remapping affect insurance?

Not necessarily. However, you need to inform your insurer of ANY modification you make to your car, including Engine Remapping and Tuning.
Does Diesel Engine Remapping affect my warranty?
This is a grey area - if in doubt you should check with your dealer. However, note that many Remapping firms will offer their own, equivalent, warranty, meaning that you will be covered either way.
How much does Diesel Engine Remapping cost?
Diesel Engine Remapping (or 'chip tuning') costs from £250. Costs will increase depending on the degree of remapping you require, whether you require a mobile visit instead of visiting the garage, and the complexity of your car's software.
Hopefully our FAQ section has answered some of the questions you may have about diesel tuning. However, if you would like more information, we have produced the following guide to help you understand the subject in greater detail.

Diesel tuning is a job which effectively reprograms the Engine Control Unit (ECUs) in your car and changes variables such as fuel pressure and ignition timing.

Technically this job is not a repair as there won’t be anything wrong with the car having a tuning job carried out.

This service is also known as remapping.

What is the ECU and how is it tuned?

The whole point of remapping a car is to improve its performance by changing the default settings on the ECU.

The ECU is the brains of your car as it dictates the levels of fuel going to the engine and all of the most important functions of the vehicle.

When a new car is sold, a manufacturer will typically have the ECU set up to limit the performance of a car.

This is because a car model will require different settings from one country to the next depending on the environment.

In hotter conditions the car will need more power to be sent to the air conditioning system where as a milder environment will not require as much energy to be spent on air con.

Remapping a car doesn’t have to mean changing the setting to custom ones, it can simply mean making sure they are all correct.

Unless you are a trained professional do no attempt to remap your car as you could completely destroy your engine as soon as you start driving.

What difference does it make?

Adjusting settings will deliver a much improved performance in your car which is why it may be worth having a diesel tuning check.

If you have a successful remapping, you could benefit from a drastically improved car.

The engine may have a better response rate, it may be easier to overtake, the fuel consumption may be improved and you may not have to change gear as frequently.

Tell your insurer

Remapping is classified as a car modification and so your insurer has to be made aware of the change which is why you should check your insurance before the job is completed.

If you have the job completed and then decide to tell them, your insurance could be made invalid.

Some will simply ask you to pay a premium however it depends entirely on the insurer.

What is the cost of remapping a car?

Remapping car cost varies on the car and the garage which is why you should always shop around to find the best garage and deal.
