1. A method for trimming a fuel injector in electromechanical communication with a fuel injection system simulator, the injector being operable to generate, in one injection event, a first and second shot and produce an second shot delay in response to an electronic control signal delivered by the simulator, the control signal generating a respective, first and second signal pulse and an second signal delay, the method comprising the steps of:selecting operating conditions of the fuel injection system simulator; testing the injector at the selected operating conditions; detecting the actual operating conditions of the injector; comparing the actual operating conditions to the selected operating conditions; and adjusting parameters of the electronic control signal if the actual operating conditions do not equal the selected operating conditions.
