However, with the amount of information ECU’s process and their proximity to the heat and vibrations of the engine, they can sometimes need break. ECU programming is the process of taking a ROM file and placing it into permanent storage inside a vehicle's engine management ECU. When your car is remapped, the tuned software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance engine performance. Remapping, sometimes called ECU tuning, is when the settings of a car’s ‘engine control unit’ (ECU) is altered to improve several areas of the vehicle’s performance. The electronic control unit (ECU) used in today’s cars and trucks is used to control the engine and other components’ functions. ECU’s made by Bosch, Siemens and Delphi are the most common, there are also Ford EECV and Visteon. The repository highlights and provides access to the research outputs created by staff and post graduate students at Edith Cowan University. It is also often referred to as the PCM (powertrain control module) or ECM (engine control module). Sensors are located throughout a car engine and they all feed into the ECU which processes the information they provide. The ECU, or engine control unit, is a major component of your car's onboard computer. This electronic module is a built-in computer which your vehicle depends on for managing a variety of its systems and functions. The programme in the ROM is not editable. Think of it as the vehicle’s brain. The ECU is an expensive component and so having it repaired or replaced could set you back depending on the extent of the damage. It controls the operation of the internal combustion engine, including the fuel dose, injection angle, turbocharging pressure, and fuel injection pressure. The ECU is normally positioned at the top and back of the engine bay (Picture iStock/jaym-z) Modern cars are more like computers on wheels and central to that is the ECU. The ECU (Engine Control Unit) is the “brain” of every car. Engine Control Unit. Ecu definition is - any of various old French units of value; also : a coin representing an ecu. The ECU contains three types of memory: ROM, RAM and PROM (or EEPROM). The main purpose of remapping an ECU is to change the performance of the engine. A flashed ECU is pretty much going to have to go with the bike, and you may, or may not get the value back. Really, you can think of the engine control unit as one part of your car’s brain (it’s responsible for controlling the engine). All this is computer controlled. "The number of ECUs in a vehicle is increasing due to the development of various information, safety and driving-support systems, and as a result, the demand for smaller ECUs is growing," said Mitsuhiko Masegi, managing officer in charge of DENSO Corporation's Driving Assist & Safety Product Division.
