Abstract
A fuel injector assembly includes a plurality of fuel injectors ( ), each of which may have a different performance characteristic. After the performance characteristics have been determined, an internal, energizable voltage or current source ( ) is provided within the injector housing ( ). Each time the vehicle ignition is turned on, a controller ( ) queries each injector ( ) to obtain a signal from the individual, internal, energizable voltage or current sources ( ). The controller ( ) then uses the output of the internal voltage or current source ( ) as an indication of the performance characteristics of each injector ( ). The controller then customizes the power signal supplied to each injector to accommodate for different performance characteristics.
