The fuel injection controller is an electronic device for the "Generation I" Chevrolet V8 engine. The fuel injection controller measures rotational position and rotational speed for both the crankshaft and the camshaft. The uniqueness of this design is that it repackages the internal components from a standard front-mount location "Optispark" distributor normally found on a "Generation II" Chevrolet engine into a housing that mounts the components internally in a top rear-mount location on "Generation I" Chevrolet engines. The fuel injection controller then allows use of a standard production Chevrolet "Generation II" fuel injection computer (not a part of this patent) for a "Generation I" Chevrolet fuel injected engine. Because of insufficient information for rotational position and rotational speed for both the crankshaft and the camshaft, "Generation I" Chevrolet engine fuel injection computers were restricted to operate in "batch fire". Batch fire means all the injectors on one bank of a V8 fire, then all the injectors on the other bank fire, etc. This fuel injection controller and associated Chevrolet "Generation II" fuel injection computer (not a part of this patent) allows sequential control of the fuel injectors on a "Generation I" Chevrolet fuel injected engine so that each injector fires only when the intake valve is opening. The fuel injection controller and associated Chevrolet "Generation II" fuel injection computer also allow electronic "flash" programming of engine control parameters where previous "Generation I" Chevrolet fuel injection computers required reprogramming via changing a replaceable EPROM.
