Abstract
An electronic engine fuel controller that is simple, cheap, easily installed, and configurable for any internal combustion engine. The system is intended for upgrading older carbureted vehicles or vehicles that have been modified beyond the limits of the OEM controller. It takes advantage of micro controller technology with integrated memory, digital inputloutput, sensor and timer channels to produce a low parts count, as well as reliable operation in a variety of vehicles, even when installed by people with little experience in this area. Operation is by sensing a tachometer signal from the existing distributor, or similar device that produces one pulse per cylinder cycle. When a pulse is received, software in the micro measures engine parameters, calculates fuel parameters, and fires one or more injectors. Software on an external computer communicates with the micro, allowing the user to modify any of the controller parameters.
