Abstract
A method for controlling a fuel injector of an engine system includes applying a pull-in current to close a spill valve of the fuel injector and detecting a timing at which the spill valve closes. The method also includes adjusting at least one of an amplitude of the pull-in current, a duration of the pull-in current, or a timing of a start of an application of the pull-in current based on the detected timing of the closing of the spill valve.
