From my understanding the injector should stay pulled to ground 0.0v for the inj open time and the current should ramp up much faster.
I am using a FJO Electronics Peak and Hold Injector driver, as my ECU has only high impedance injector drivers but I am using low impedance higher flow injectors............ I am about to pull this box out and put in a resistor pack as it looks faulty to me. Am I missing something here?
