I am working on a wireless tach for a class project. Well, aside from a
ground wire, its wireless. It has an antenna that senses the spark when
placed against a spark plug wire, turns it into a logic level pulse and
is sent to a microcontroller. When I tested it on the Sporty, it seemed
fairly accurate on the rear cylinder, but it seems it was reading twice
the expected RPM on the front cylinder. Is there any reason the front
would fire every revolution when the rear only fires on the power
stroke? It could still be a flaw in my design. Just curious.
