Delco ECU used in General Motors vehicles built in 1996. 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.
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.
The Modular Engine Management System, or MEMS, is an electronic control system used on engines in passenger cars built by Rover Group in the 1990s. As its name implies, it was adaptable for a variety of engine management demands, including electronically controlled carburetion as well as single- and multi-point fuel injection (both with and without electronic ignition control).
Trionic is an engine management system developed by Saab Automobile. It consists of an engine control unit (ECU) that controls 3 engine aspects: Ignition timing; Fuel injection; Acts as a boost controller. The numerical prefix 'tri-' yes (Tri being three) in Trionic. 'Ion' comes from the fact that it uses ion current, measured by the spark ...
The valve (or valves in newer models with multiple valves to create more than 2 lengths) is either fully opened or fully closed. An example of early single-valve ACIS programming would be the 3.0L 3VZ-FE engine. The ECU actuates the VSV to close the valve when the throttle position is 60% or greater and engine speed is 3,900 RPM or more.
Example partitioning of a system basis chip with bus interfaces (green), central logic (yellow), and outputs (red) for voltage regulators (LDO), high-side, and low-side switches (HS, LS) A system basis chip ( SBC ) is an integrated circuit that includes various functions of automotive electronic control units (ECU) on a single die.
The second group buy in 2002, as well as all following purchases until 2005 are V2.2 main boards, and have a V2.2 printed in the upper left corner of the PCB. MegaSquirt ECU's have not been sold by group buy since 2002. Instead, vendors resell the Bowling and Grippo offerings, and they keep stock current, so all items are normally available at ...
