Review on ARTILAURA Tachometer Pressure Multifunction Tacometro Replacement Parts in Lighting & Electrical by Tony Ledbetter

It's hard to tell which ohm range transmitters it was designed for; I've never seen anyone sell them to answer a question. .I also understand that it is not intended to be used with a coil signal to control a tachometer; or at least for me, even with the pertronix electronic ignition, the update is very slow when it does, but often just stops on a read. With no idea what transmission devices to use and no ability to control touch. What? hall sensor maybe? I'm not sure what to do about it. The hour meter works.
