Thanks. This looks like just the ticket for getting my CX500 motor going. Will have to look at pulser output to turn it into HEI trigger. Do you have any specs for the HEI input? Does it trigger on the edge or the level(does it have any debounce build in? If so, how long must the level remain or 'average' low?

Using the HEI with stock pulsers requires a lot of info on the pulser's output. Most pulsers are actually reluctors, that is, basically a tiny AC generator. The real issue is how the dwell is handled. The HEI has a dwell compensation feature which can mess things up. With the KZ, I don't use the HEI's dwell compensation at all.
The details are here. Click on my notes for the HEI to get details on how it works.

I have received a lot of emails on using the HEI modules with Honda reluctors from the early 1980's, but I can't get any reliable data from the emails. I really need to get a Honda reluctor to study it's signal. Then I'm sure I could figure out a good circuit. The Honda reluctor is different from that of the KZ, so the circuit may be different from the one I describe for the KZ.
