Thanks for the replies.
Yes I am trying to find injector timing off of a mechanical system. The crystal microphone sounds like an interesting way of picking up that signal.
I will scope one out. I am guessing that that signal will contain quite a bit of ambient noise as well, hopefully the...
Thanks for the input.
I am unsure of the type of sensor used but once this is figured out the downstream electronics will be quite easy to make.
Chances are it will be a simple voltage follower with some gain and perhaps a schmitt trigger to square off the wave depending on what the timing...
Hello:
I have seen a tool at Snap-on (p/n MT257A) that wraps around the #1 high pressure injection line. This sensor will pick-up the timing of the firing of injector #1 so that the user may time the vehicle.
Does anyone know how this device works? I would like to build one instead of paying...
