Abstract
An engine control system that is configured to be attached to the intake port or intake manifold of a reciprocating engine. The system can be designed to allow installation as original equipment or as a retrofit unit. In either case, the system provides the engine with a dual ignition and electronically controlled fuel-injection. The system includes a master control unit (MCU) that utilizes a firmware operated microprocessor. The MCU is connected to a plurality of sensors that sense critical system parameters that determine the engine settings. All system parameters are user-controlled by three system command switches that are located on a control display unit (CDU). The CDU is attached to the MCU by an electrical cable and is positioned on the vehicle to provide easy accessibility.
