Subject: CorvairEngines-List: tachometer

I've got a Van's tachometer that was in the partially completed project I b
ought.=C2- Has anyone used one of these by tying the sensor wire to the n
egative side of the coil?

As best I can tell, the tachometer used by Van's Aircraft and also sold by 
Aircraft Spruce is a Isspro model, and uses a sender that produces 8 pulses
 per revolution.=C2- Fairly certain that our coils will be producing 3 pu
lses per revolution.=C2- This is rather disheartening, because now I have
 to find a tach that will fit a standard 2.25" instrument hole and bolt pat
tern.

Ernest, I first used an E1 from MGL avionics. It worked well with a few
wraps about the high tension lead to provide the tach input.

I have this unit sitting on a shelf collecting dust if you're interested,
as I've replaced it with another engine monitor package.

Want it? Make a ridiculous offer.
