1. A method of determining an instantaneous absolute engine crankshaft angle position, the method comprising:

  • measuring tooth time inputs of an engine-mounted timing wheel;

    scaling the tooth time inputs into angles in an angle domain;

    cross-correlating the angles with stored tooth pattern angles; and

    determining instantaneous absolute engine crankshaft angle position as a result of a match between the angles and the stored tooth pattern angles.
