Could somebody here tell me how to judge the open time for GDI system injector? There should be a point on current waveform show the injector is starting to open. But I can’t see it on my waveform. I guess the action of GDI is very very fast, so we can't see the point.
And regarding to a waveform built-in PicoScope Automotive software(actuators –injector –VAG PD), the waveform notes in the help file said “At the point of injection the current rises from zero to around 15 amps where there is a brief interruption before continuing to rise to just over 17.5 amps”. I can’t see the 15 amps point on the waveform.
