Ignition upgrade to full coil system

Dear Bill, the only concern that I had about the MegaJolt system you recommend is that it does not have an engine knock sensor. I'm less concerned about the spark than I am about the ignition curve, in order to avoid detonation.

But I see another virtue in your suggestion ; if it works then it's a much cheaper solution than the one I've found. It merits a test. I shall do so.
