Hi John,
No, and if there is it will be way off. When I disable the primary
injectors, my tach reading doubles on the EM2. I suspect there is a
spike at the leading and trailing edge of the signal when it's disabled
but I haven't put a scope on it to see. If there are spikes, your tach
might or might not respond to them. That probably leaves the ignition
as a source for a tach signal. I'll check with Tracy to see if he has
any thoughts about it. I don't want to connect anything to the coil
signals without his approval.

Bob, while sitting on the back porch watching the grass grow and running the plans of the carb heat through my mind, I got to thinking about a post of a couple weeks back about tach signals. Does the box you sent me to try, pick up the signal for the tach from the injectors? If it does, while using the carb (Weber 48) will there be any signal for the tach with the injectors disabled.
