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 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 ECU from a Geo Storm 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 .
Adaptive AUTOSAR is developed and written using C++ which is an object-oriented programming language. The communication protocol used for the in-vehicle networking is SOME/IP, based on Ethernet. Two types of interfaces are available: services and application programming interfaces (APIs). The platform consists of functional clusters which are ...
The first generation of engine management controller for CART racing used a modified production ECM, but performed poorly in the race car due to the harsh EMI (Electromagnetic Interference) environment. This version was never used in racing, but the experience gained enabled the engineers to design a more successful Generation 2 controller for ...
Most MegaSquirt vendors ship the MS1/Extra firmware as standard on MS1 boards. The firmware is designed to operate using either a supported ignition system, such as GM HEI, or Ford EDIS, or it can decode certain trigger wheel signals from crank/cam sensor pickups and directly run wasted spark or coil on plug. MS1/Custom Suzuki G13B [8]
To ensure high quality in the Computer Command Control system, it will be given a final check at the end of the assembly line. Here the completely assembled vehicle will be tested by connecting the computer to a test computer. This will significantly improve GM's ability to catch anything wrong with the system or the car's engine." [1] [2] [3]
It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control Module (BCM), for a total of three separate computers. These automotive computers are generally very reliable.
