Abstract
An ignition and fuel control system of a vehicle is provided including a controller . The controller is electrically coupled to an ignition system , a fuel system , a crankshaft position sensor , and a camshaft position sensor . The crankshaft position sensor senses a crankshaft position and generates a crankshaft position signal. A camshaft position sensor senses a camshaft position and generates a camshaft position signal. The controller determines a crankshaft position and a camshaft position in response to the crankshaft position signal and the camshaft position signal respectively. The controller identifies a reference engine cylinder in response to the crankshaft position and the camshaft position and generates a synchronization value. The controller also enables the ignition system and the fuel system in response to the synchronization value.
