I don't have a pizeo type, but I do have a fox valley luminosity type that I'll never use and would part with. It has a thing that you put in the #1 glow plug hole and it detects the ignition flash. If it's of interest message me, if not I really guess I need to post it for sale to one of y'all that want to scientifically time you're engine. I got all hot and bothered about it quite a while ago but then got to thinking about all the variables that go into igniting WMO and mechanical injection and pop values and realized.......there is no real way to time a mechanically injected diesel that is running on fuel that varies in viscosity from fill up to fill up..... anyway, let me know!
