Most likely your tach is receiving a pulse from both systems. Some where
the two systems are interconnected. Chase out your wiring to find the
point
that connects both systems t

Mark:
Do not put a jumper between them as it will short the two ignitions
together. The safest way is to switch the tach wire when you switch the
ignition.
That requires a separate deck on the switch but is the safest and most
reliable.

Mark,
You should be able to do it using 2 diodes 1n4155 fast switching high
current anode side to the coil and both cathodes to the tack. This should
keep them from back feeding to the other coil.
