Thanks for the info Dave & Bob! I talked to Doug Reed at Superformance South. It just so happened he had a step-by-step procedure for the changeover that he so graciously e-mailed me. He also informed me that my current Smith's tach would not work..something you already told me. He referred me to Mark Dove at Dynamic International, who sells replacement Smith's tachs that will recognize the square wave that the MSD generates. Thanx, Ray
