In 1981, a Delco Electronics ECU was used by several Chevrolet and Buick engines to control their fuel system (a closed-loop carburetor) and ignition system. [10] By 1988, Delco Electronics was the leading producer of engine management systems, producing over 28,000 ECUs per day. [11]
The development of an ECU involves both hardware and software required to perform the functions expected from that particular module. Automotive ECU's are being developed following the V-model. [ 1 ] Recently the trend is to dedicate a significant amount of time and effort to develop safe modules by following standards like ISO 26262 . [ 5 ]

The telemetry system developed for the 1992 season was used, and a new Distributor-less Ignition module component was added to the overall engine management system. 10 wins including the 1993 Indianapolis 500 in 16 CART races.

A very steep coding, electronic design, and tuning curve prevented the system from gaining wider acceptance. [1] The designers then decided to simplify the EFI332 design, and focus on managing the fuel injectors (the EFI332 was also designed to control the spark plug ignition system if so desired). This was the basis for the first MegaSquirt ...

VEMS is a commercial engine management system. VEMS is unlike most other EMS's in that it used to be public domain and then a form of open source. History
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).
