Why Do I Need a Remap?

Manufactures sell vehicles with a standard set of map files on the ECU, as they 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 sales tactics. For example; BMW needed to limit the power of the 335D, just so its pace isn’t that of an M3.

Performance ECU tuning is essential for those drivers who feel their vehicle is not living up to its full potential. By increasing the power of your vehicle, you are providing yourself with a more pleasurable car to drive, that puts that smile back on your face.

Whether the gain is 5 BHP on your 1.4 Ford Focus or 55 BHP on your BMW 335d, when you choose a JF Automotive ECU performance map, you will wonder why you didn’t choose us sooner!
