tachometer
 (United States)

I bought a SunPro Tachometer and could not get it to work.  I called their representative and he told me their tachs work off a ".5v square wave" (whatever that is) and I needed a 12 volt tach.  Would someone tell me what aftermarket brand and model tachometer they have on their RX7?

IIRC, any 4-cylinder tach will work, hook it to the trailing coil.
