Specialist ECU Remapping Bristol


What is an ECU?

The engine inside of all modern vehicles is electronically controlled by an ECU (Engine Control Unit), which is constantly processing formation that is received from multiple sensors. Engine fuelling, torque values, boost, and ignition timing are all calibrated within the ECU code based om the conditions in which the vehicle is being used, the altitude, the quality of the fuel in its tank, and more. Working alongside the sensor information, the relevant tables (or maps), are used to keep the engine running at high performance, whether it is being asked to deliver high or low output. 

What is ECU Remapping?

When a manufacturer develops a new car or another motor vehicle, they have to take into consideration all of the conditions that it may be subjected to in all regions in which they sell the model of motor vehicle. This means that instead of just optimising the ECU’s program or map to deliver the best performance or best quality fuel efficiency, they have to make compromises to the map to take into account these potential differing operation conditioning. These could potentially include sub-standard fuels extremes in temperature and altitude, differing emission laws, and the possibility that the vehicle may not be serviced on a regular basis and in accordance with the scheduling instructions. 

In simpler terms, ECU Remapping is taking a reading from the ECU’s processing chip of the vehicles standard compromised map and adjusting various individual parameters within the map such as fuel pressure, boost pressure, ignition advantage and throttle pedal control amongst others to release the true performance from the engine. ECU Remapping is an entirely safe process as it is just giving the engine the performance it should have had in the first place. Every single engine will have its own unique map and by making adjustments, we can tune the characteristics of the engine, unleashing more power and reducing fuel consumption in many cases.


What are the benefits of ECU Remapping?

Not only will ECU Remapping improve the engine’s power and torque figures, but it will also dramatically sharpen the throttle response and widen the power band. This will then make the power delivery noticeable more linear, which in turn will make the vehicle feel livelier to drive and the engine far more flexible. Frequently, the vehicle’s power output is restricted by the manufacturer of the vehicle for no other reason than to ensure that it fits into a class that will suit fleet buyers.

The other key benefit of ECU Remapping will be a significant reduction in fuel consumption. With the extra torque, you will notice fuel-savings as it will require less throttle to maintain speeds on motorways and you will be able to drive in a higher gear at a slower speed, and the additional power is incredibly useful when towing or have additional load.
