I did a search but could not find any direct threads on this topic. I'm interested in converting to a waste-spark DIS using something like the old Ford EDIS-4 system. Seems many vintage guys have done this using ECUs of various brands. Advantages are electronic timing both advance and retard, no external vacuum lines or potential leaks, much higher spark efficiency (no dizzy losses), no moving parts other than the crank wheel obviously. Anyone play around with these?
