An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
A host of functions required for ECU software calibration, such as interface-dependent calibration methods, calibration data management, measurement data visualization and analysis, ECU programming, vehicle bus monitoring, as well as remote control through standard interfaces, are part of the product's functional complement.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.
A controller area network (CAN) is a vehicle bus standard designed to enable efficient communication primarily between electronic control units (ECUs). Originally developed to reduce the complexity and cost of electrical wiring in automobiles through multiplexing, the CAN bus protocol has since been adopted in various other contexts.
0x04 Safety System Diagnostic Session offers largely the same as 0x03 Extended Diagnostic Session, but does not always offer sensitive or unrelated services and/or sub-functions. It may offer further routines and data transmission sub-functions. 0x11 0x51 ECU Reset The service "ECU reset" is used to restart the control unit (ECU).
Today, the term chip tuning can be misleading, as people will often use it to describe ECU tuning that does not involve swapping the chip. Modern electronic control units can be tuned by simply updating their software through a standard interface, such as On Board Diagnostics. This procedure is commonly referred to as engine or electronic ...
ECU extract: contains the information from the System Configuration Description needed for a specific ECU (e.g. those signals where a specific ECU has access to). ECU Configuration Description: contains all basic software configuration information that is local to a specific ECU.
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
