If possible I plan on getting one of these devices when I get to the point of automobile engines. I wish they had an item that would do timing adjustment on small engines as I would like to get these working on hydrogen alone. I think this would be a great learning experience that would create more knowledge to tackle many of the problems associated with the use of hydrogen in larger engines. At any rate I am beginning small.
I think I would prefer many monitors while in the experimental stages while operating any type of timing control.
