Fuel – The amount to put in as a response to throttle and load.Air Intake – The amount of air that should be allowed into the engine as a response to throttle.The ECU controls different factors like the following : The most important point is that the re-mapping of a vehicle does not have any negative effect on the life of the engine or exhaust emissions. Greater response, more power, and lesser fuel consumption come as one among many advantages that the remap offers. Remapping of the engine can enable the lifting of few restrictions forced on the vehicle by the manufacturer.ĮCU re-mapping removes the blocks on a few of manufacturers’ restrictions and facilitates the vehicle to perform like how it did when was designed originally. So the introduction of ECU is quite commendable. It takes only a few seconds or a maximum of minutes for the process. Moreover, the time consumed for bringing the values back to the proper ones has become really low. The process of calibration and re-calibration has become really easy. Its introduction has brought great changes into the field. But the ECU or Engine Control Unit has simplified the entire process.

Setting the ignition time, air-fuel mixture, and idle speed in that way is very difficult.Īlso, the dynamic nature of controlling was restricted. The data is interpreted using look-up tables or performance maps that are multidimensional and the engine actuators are adjusted accordingly.īefore the ECU, ignition timing, air-fuel mixture, and also idle speed were set on a mechanical basis and controlled dynamically using pneumatic and mechanical means. This is done by reading values got from many sensors that are kept inside the engine bay.

ECU or an engine control unit is a kind of control unit that operates electrically and controls a series of actuators in a combustion engine inside so that the engine performance will get optimized.
