Manufactures sell vehicles with a standard set of map files on the ECU so they can be shipped all around the world. Vehicles are shipped around the world meaning they have to deal with different climates and a magnitude of fuel types and quality, this is why the manufactures set a standard map that will simply work anywhere.

Power and fuel economy is also limited on these maps because of market placement and sale’s tactics. For example; BMW needed to limit the power of the 335D just so its pace isn’t that of an M3. Another great example is manufactures and their new eco friendly cars like Blue Efficiency and Blue Motion, they get away with selling these models at much higher prices for a more fuel efficient map to the ECU. JF Automotive can remap all vehicles petrol or diesel to make then run cleaner and more fuel efficient even if it is a Blue Motion from VW or Blue Efficiency from Mercedes-Benz.

We also tune taxis, motorhomes, vans, trucks and even boats for fuel savings!

Frequently Asked Questions

Will the lifespan of my engine be reduced?

No. Our remaps are designed specifically to improve the performance of your vehicle whilst remaining within the tolerances of your vehicles’ components.

Sadly, in attempt to achieve ‘big numbers’ some other companies over tune engines, placing excessive stress on the engine, transmission, cooling systems, etc, leading to reduced life span and reliability of the vehicle. We pride ourselves in producing reliable remaps which do not over stress your vehicle but still produce impressive results.

How long will it take to remap my vehicle?

The JFA custom written OBD remap will usually take between 1-2 hours, depending on the vehicle. However, some vehicles especially those requiring bench tuning or dyno can take up to a whole day. Get in contact with us for an idea of how long it will take us to tune your vehicle.

Can the remap be reversed?

Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.

Why we don't you offer ECU remapping for £200!

We get asked, “Why do some tuners charge as little as £150?” There are a few factors as to why we do not offer remapping for £100-£200!

We supply custom written files for each vehicle that we remap that take in to account condition, milage and customer request of each vehicle. Our services are fully insured with a 30-day money back guarantee and lifetime support for the tuning software supplied. We constantly invest in the most up to date tuning and diagnostic equipment and software and we offer a quality service to all our customers.

Overall our custom supplied tuning software is of the highest standard that we know of, so if you want the best of the best, choose JF Automotive.

What if a main dealer wipes the map with a software update?

No problem, simply bring the vehicle back in and we will take a fresh read of your ECU and write you a new map file free of charge. We offer this as part of our lifetime software support.

I have existing modifications, will this affect the remap?

Some existing modifications can improve the gains made by remapping a vehicle, and modifications to parts such as air filters and exhausts reduce restrictions of manufacturer parts. We offer a range of remap packages to cater for a whole host of modifications. If you wish, you can order modifications from us to compliment your map and have them fitted when we remap your vehicle.

What is covered with the "30-day money back guarantee"

In any case where a customer is dissatisfied with any ecu remap software supplied, within thirty days of the supply date, the customer can request their money back. In order for any refund to be processed, the customer must present their vehicle to our workshop and allow our technicians to restore the vehicle to its original state. On successful completion JF Automotive will refund the cost of the remap to the customer.

No refund can be granted unless the vehicle is returned to the original state by JF Automotive. The 30-day money back guarantee only applies to stage 1 remaps and does not apply to other services like pops and bangs, parts or dyno sessions.
If another modification is purchased alongside a tuning file, which relies on a remap to operate, only the cost of the file is covered by this guarantee. We reserve the right to withdraw this 30 day money back guarantee.

Do I need to notify my insurance company?

Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle. Many insurance companies do not penalise you for upgrades of this nature, particularly if you’re tuning for increased economy however a failure to disclose modifications may invalidate your policy. You may wish to enquire with your insurer if the modification will affect your policy prior to choosing one of our services.
