FAQs

ECU remapping is the process of amending the software written into your vehicle's engine control unit (the brain of your engine). Generally, a remap is performed to fine-tune instructions that are sent to various components in the engine, sometimes to encourage them to work a bit harder or more efficiently. This results in more power, torque and in diesel engines, better fuel economy.

If your car or van is lacking the pull power for towing, come to us and we will give your vehicle a specific custom remap that is focused on the torque and power at lower rev range.

Alternatively if you are after better acceleration we can make your car more responsive with a safe boost of BHP and Torque to increase your 0-60 - this option is called a stage 1 remap and you could also gain better MPG.

If you do a lot of motorway driving or require better MPG we can give you an increase in power as well as better MPG with one of our economic remaps.

Yes, a professionally completed ECU remap is safe. At JM Performance, we enhance your engine only to what its components can handle. We follow strict guidelines and proven tuning methods, performing both pre- and post-remap diagnostics to ensure safety.

If you’re wondering why your friend’s or family member’s car seems to have better or worse performance gains than your vehicle does, this is likely because all or some of the components have different stress thresholds. Even if you have the same make and model, the trim or age of the vehicle may mean that the components that we optimise have slight differences in tolerance.

Put simply, it’s a form of brain surgery for your vehicle designed to improve performance and economy. We have a wealth of experience in providing remaps for a variety of vehicle types.

Even if a decade or two old, your vehicle will likely be fitted with an Electronic Control Unit (ECU). This ‘electronic brain’ controls various engine functions such as fuel mixture, ignition timing and turbo boost pressure (where fitted) to various pre-set parameters programmed into it at the factory

All we are doing when we remap your vehicle is modifying its engine management software. This in itself does not harm your vehicle.

If a customers wants a standard remap to produce more power and torque (with any fuel economy increases a bonus), then it is perfectly safe and harmless to your vehicle. If a customer comes in a says “do your worst, sky captain”, then we have to warn them of any potential problems that could occur.

Your vehicle/engine is perfectly happy with additional Torque and BHP however if you go over board and give it too much power then you run the risk of putting added strain on various components. Your clutch, turbo, injectors, tyres and fuel economy can all suffer as a result of trying to extract too much power from your vehicle. If your vehicles engine had a life expectancy of 300,000 miles then by having a harsh remap applied to it, you could be reducing it’s lifespan to 280,000 miles. It’s all dependant on how you drive your vehicle.

Yes, your vehicle is being ‘fine-tuned’. Although your fuel consumption may go up or down depending on the type of tune you opted for, it will be burning the fuel more efficiently due to being finely tuned.

Insurance policies vary. If your policy requires you to report modifications to the engine management software, you should inform your insurance company about the remap.

• Remapping can affect your car's warranty depending on the terms and conditions set by your warranty provider. It's important to check with your warranty company before proceeding with a remap. At JM Performance, we ensure that our remaps are within safe limits to minimize any potential impact on your warranty.

If it says that remapping your ECU will affect the warranty in your service book or vehicle documentation then it is likely that it will affect part of your warranty. We have been advised that the onus is on the warranty company to first prove you’ve had the car remapped. If it can be proven that the vehicle has been remapped then it is then up to the warranty company to actually prove that any modifications you have done to your vehicle has physically induced your warranty claim.

Because every vehicle is different, we have a database of power gains we can achieve for all the vehicles we tune. You can search this database as often as you want to find out the BHP & Torque increases we can achieve by remapping your vehicle. Please see the Find My Vehicle page to find out more.

Absolutely! You'll notice the difference immediately. We take you on a test drive post-remap to ensure you're satisfied with the enhanced power and/or fuel economy. You only pay once you're completely happy with the results.
