Abstract
Methods and systems are provided for controlling fuel injectors included in a fuel injection system of an internal combustion engine of a vehicle. The fuel injection system includes a fuel rail. The methods and systems measure data for the fuel injector relating fuel injection flow rate and fuel injector energization time at a first rail pressure. The methods and systems transform the measured data using a correlation function t to correlated data relating fuel injection flow rate and injector energization time at a second rail pressure different from the first rail pressure. The methods and systems control the fuel injector using the correlated data relating fuel injection flow rate and injector energization time.
