Why Prime Motive?

​

Since the early 1990's we have been tuning engine control units (ECUs), we started off tuning Porsche and BMW engines fitted with the early versions of the Bosch Motronic ECUs and soon began expanding our knowledge to include other brands of vehicles and ECUs. All our code respects current MOT emission tests, will not compromise the design limits of the engine or transmission and will, in most cases improve your vehicles "like for like" fuel consumption.

Why tune or remap a vehicle's engine?

​

Vehicle manufacturers produce different models for various markets around the World, they also wish to maintain a model hierarchy that prevents a lower powered engine encroaching into the model above it. Eg. A BMW 320i and 330i fitted with the B48B20A engine, share mechanically the same 4 cylinder 2.0 turbo charged petrol engine. The power is restricted simply by the software inside the ECU. In this case their standard power would be 181bhp vs 254 bhp, both of these vehicles can potentially be tuned to 300 bhp!

​

Forced Induction Petrol Vehicles

 

Large power and torque gains are achievable on these engines, up to 25% or more, depending on the vehicle and engine type. The vehicle will feel more responsive and eager with the power coming in earlier and not tailing off further up the rev range. Overtaking ability will be greatly improved as well as in-gear flexibility.

 

This is achieved by not only fine tuning, the "map" in the E.C.U. for fuelling and ignition requirements, but also raising the boost levels; we do this well within the original threshold design parameters of the engine, so that long term reliability is unaffected.

​

 

Turbo Charged Diesel Engines

 

These engines are capable of the most impressive gains from our software, up to 30% or more power and torque is available. These gains depend on the vehicle and engine type, because of the natural characteristics of a diesel engine, torque is always impressive on these engines once they have been optimised.

 

Power will be available through a much wider band than before making for a much nicer and safer drive. Overtaking is more relaxed and as a big benefit (driving style dependent), fuel consumption can be improved due to the engines ability to "pull" in higher gears. This is useful for towing, 4x4's and MPVs.

 

Normally Aspirated Engines

 

Non-Turbo engines, also known as normally aspirated or NA engines, can obtain up to 10 - 15% more power and torque depending on vehicle and engine type. We achieve this by electronically fine tuning the "map" or software in the vehicle's electronic control unit or ECU.

 

In addition to greater power and torque, we will eliminate drivability issues such as; poor throttle response, flat spots (hesitation) and generally improve the low down torque or "pull" making the vehicle much nicer to drive.

Reduce your fuel costs

Whilst the value of petrol and diesel here in the UK is creeping up, you can reap the rewards of this simple and effective process and save yourself money too!

• Reduce fuel consumption and get more miles out of your tank

• Potential to extend the operating life of a fleet by reducing driver abuse

• Typical cost savings can be well in excess of 10% which means the cost/outlay of the re-map is covered within months

• Reduced CO2 emissions 

• Potentially longer tyre and vehicle component life
