RE: tach question
If i Remember Right It'll Show double Value because of the Different Signal From the Coil. Not sure if its Double Value or Half Value.... lol Or even if thats right

RE: tach question
if you put a tach from a 5.0 into a mustang, it will read twice the amount of a 2.3 tach. ie. if your doing 1000 rpms, it will read 2000.

RE: tach question
5.0 tach in a 2.3 will read HALF the actual value
2.3 tach in a 5.0 will read DOUBLE the actual
so in a 2.3 with 5.0 tach it will read 1000 when the engine is actually at 2000
It's fixable, but you have to take the tach apart. Requires removing a couple things & soldering in a potentiometer.
