That's so cool, I didn't know I needed one of those until I saw this thread... LOL Seriously, that's DAMN COOL.
One issue I had in the past with an electronic distributor, the phasing of the reluctor wheel was off because the roll pin was in the wrong slot. Most of the reluctor wheels have 2 spots for the roll pin to go into. In my case when the vacuum advance can was "on" (pulling full advance) the reluctor teeth would be too far out of phase and it caused slight hesitation/surging at cruise. Pulled the reluctor wheel and reinstalled it in the other roll pin slot, problem solved.
