Abstract
An ignition and fuel control system 10 of a vehicle 18 is provided including a controller 22. The controller 22 is electrically coupled to an ignition system 14, a fuel system 16, a crankshaft position sensor 32, and a camshaft position sensor 34. The crankshaft position sensor 32 senses a crankshaft position and generates a crankshaft position signal. A camshaft position sensor 34 senses a camshaft position and generates a camshaft position signal. The controller 22 determines a crankshaft position and a camshaft position in response to the crankshaft position signal and the camshaft position signal respectively. The controller 22 identifies a reference engine cylinder in response to the crankshaft position and the camshaft position and generates a synchronization value. The controller 22 also enables the ignition system 14 and the fuel system 16 in response to the synchronization value.
