I have it setup on the sniper to take the rpm signal from the neg side of the coil (no timing control), it's the first selection in that part of the sniper setup. I think the analog unit is fooling the sniper and giving it a "usable" tach signal. I don't know what that ready to run distributor is putting to the coil, but I think it's some kind of pulse that the sniper is not happy with. I already wanted to do timing control anyways so I'll be contacting you about one of those Holley EFI dual sync distributors.
