ECU Remapping

All modern vehicles including cars, motorcycles, trucks, tractors, even boats and jetski's contain an ECU or Engine Control Unit that is effectively a small computer which controls how the engine works. Information such as ignition advance, air/fuel mix values, fuel pressure and on forced induction engines, turbo pressure values are all sent to the engine from the original software written on the ECU. Vehicle manufacturers de-tune the engine by setting the software on the ECU to default before sending the vehicle out.

This is done due to the manufacturers having to sell their cars all over the world, this means that the software settings on the ECU must take into account different climates & altitude extremes, different laws & restrictions and varying quality of fuels. Vehicle remapping is basically the modification/replacement of the manufacturers default software, releasing the full potential of the engine. This operation is completely safe and reliable, with the new software settings, the engine components would not be operating outside of the conditions the manufacturer initially intended before all the afore mentioned compromises were added. Prymus's remapping service will provide a much improved drive, with sharper throttle response, more power and smoother delivery throughout the entire RPM range and in most cases will also improve your fuel economy.

Economy Remapping

With the ever increasing cost or running a vehicle, each and every mile you can get from a tank of fuel is valuable. When we remap a car, as well as performance upgrades, we can also change the engine management software to focus on making fuel saving the priority. Due to the improved performance throughout the RPM range, improving the low end torque and widening the power-band as far as we can will mean less throttle pedal input is required to maintain cruising speeds or when driving on a gradient. It will also mean that the vehicle will be more comfortable in higher gears at slower speeds as well as requiring fewer gear changes overall. A combination of all these factors with adjusting your driving style to make the most of the extra low end torque, you will see improvements in fuel consumption. This is most effective on turbo-diesel engines, where the savings could be as much as 20%.
