Summary:A controller for an electronic fuel injection system for an internal combustion engine includes: a plurality of analog-to-digital (A/D) converters; a memory; and a processor communicatively coupled to the A/D converters and the memory. The A/D converters are configured to receive analog electrical signals representing pressures generated by a plurality of pressure sensors disposed at different locations along an air intake path and output corresponding digital signals representing the pressures, one or more of the pressure sensors are disposed in a body of a carburetor rendered permanently inoperable to mix fuel with air flowing in the air intake path, and the processor is configured to receive the digital signals representing the pressures output from the A/D converters and output a mass air flow signal representing a mass air flow rate as to an engine management system to control the electronic fuel injection system based on the received pressure signals.
