Abstract
A method for controlling a dual coil fuel injector having an opening coil and a closing coil includes issuing an opening coil pulse to the opening coil. The opening coil pulse has an opening coil pulse width (OCPW) and an opening coil turn on time (OCTOT). A closing coil turn on time (CCTOT) is calculated dependent at least in part upon the OCPW. A closing coil pulse is issued to the closing coil at the calculated CCTOT.
