ecu remapping
The engine control unit or as it is more commonly known, the (ECU), is now called the power-train control module or (PCM). This is an electronic device that controls a series of actuators on the internal combustion engine which ensures the maximum engine performance. This is achieved by reading the values from the many sensors within the engine. The data is interpreted using lookup tables' also known as multidimensional performance maps allowing accurate adjusting to the engine actuators.
The ECU has brought the performance of the engine a long way. Before ECUs, things like ignition timing, idle speed and air/fuel mixture, were mechanically set and dynamically controlled by pneumatic and mechanical means. Created by BMW in 1939, the Kommandogerät was one of the earliest attempts at using an automated system and synchronized device to maintain multiple engine functions control simultaneously. It was originally design for the 801 14-cylinder aviation radial engine for aircrafts. The device took the place of the 6 controls used to initiate the harsh acceleration. However, there were some problems; it would cause the engine to surge making it difficult for close-order flying for the Fw 190. It would switch supercharger gears at random, and harshly which had the potential to throw the aircraft into an extremely dangerous spin or stall.
The workings of the ECU would include the systematic control of the Control of Air/Fuel ratio, Control of ignition timing, Control of idle speed, Control of variable valve timing and The Electronic valve control. In some systems the ECU will control more or less functions depending type of engine and its full potential. It can even limit maintenance to the engine simply by maintaining proper handling.
