right off i'm not sure if i'm posting this in the right spot and all that so please advise. i just picked up this tach and other than figuring out it looks like the model "fz" i, in the imortal words of sgt shultz: know nothing. i will pull the gauge from the cup tomorrow but i'm guessing it doen't require a transmitter. i probably have more questions than anyone would care to read so any bits of info would be appreciated.
