A CRAZY ONE: Injector signal oscilloscoped?
Hi friends,
I hope there is someone enough "crazy" as I am to answer this one :-)
Have you guys ever connect an oscilloscope onto injector wiring?
I know that Logs trace most of it but what about local noise and signal behavior vs ECU theorical command?
I would be very interrested to get some info or graph to check how ECU manage frequency & PWM.
Any help is welcome!!!
Thank you.

yup. i've had injector signals on a O-scope. its just like you would think it would be 
the fun thing was the car we were scoping revved to 20,000 rpm. lets just say they are short pulses even at 90+% duty cycle.
