I book marked this page years ago, but just recently read it. http://www.slantsix.org/articles/bryan_ ... ong-fi.htm

Here is a quote from it:

" I simply did a temporary hookup with the controller sitting on the fender and wiring running all over the place like a mess of spaghetti. At this point I was trying to use a primary pulse from a conventional ignition coil as a reference for the controller. When we tried to fire the engine, we quickly found this was unsatisfactory, even after we tried to shape the pulse electronically. We could not get rid of false, multiple firings due to ringing of the primary circuit. A Chrysler junkyard electronic distributor and a Holley Annihilator box solved this problem, since the tachometer output from the Holley is just what the controller needs. After fixing a couple of vacuum leaks, the engine fired and ran quite well at idle in the garage." This was my story!

I don't know why I missed this, but there you go.
