Abstract
A user accessible electornic fuel injection system is disclosed which is modifiable to fit a range of engine configurations, preferably with a staged fuel injection curve and with the capability of recording speed, fuel delivery rate and other engine performance parameters. The system includes computer software which directly controls the fuel injection hardware in an automobile. This software contains a serial communication routine which services the external requests of a control program running on a personal computer, plus engine management software which controls timing functions based on engine related information.
