The engine in all modern vehicles is electronically controlled by an ECU, which constantly processes information received from a multitude of sensors. The engine’s fuelling, boost, ignition timing, and torque values, are all calibrated within the ECU code based on the conditions in which the vehicle is being used, air pressure, temperature, the quality of the fuel in its tank, and so on. Along with the sensor information, the relevant 'maps’, are used to keep the engine running at optimal performance.
How can ECU remapping benefit me you ask? ECU remapping will not only enhance the engines power and torque figures, it will also sharpen the throttle response and widens the power band. This will make the power delivery a lot more linear, which makes the vehicle feel sharper to drive and much more efficient. The vehicle’s power output is often held back by the manufacturer to ensure that it fits into a selling class. As a driving enthusiast, you do not need or want such restrictions placed upon your vehicle’s ECU, so with a conversion, you can benefit from the hidden power and torque locked away within your engine management system.
