so i saw the trailtech rpm gauge for rc's and i noticed that their is just a ring that goes on the bottom of the spark plug and no sensor, how does this work? does it pick up pulses or sparks from the coil or plug or something?

ok but stil, wrapping a wire around another then, how does it work?The one with the ring is a temp sensor that goes under the spark plug.. you just take the crush washer off and put the sensor ring in it’s place and tighten the plug down... the RPM gauge wraps a wire around the plug wire multiple times and then tie it back to itself... 2 totally separate gauges.. both work very well.. I have both on my Baja
mm makes sense, thanx.digital RPM gauges are "inductive pickup". You wrap the sensor wire around your sparkplug wire and the electrical ignition pulse is read each time the plug fires. The CPU does the conversion math and outputs an RPM based either 4 stroke or 2 depending on how you have the unit configured.
It's just to see peak rpm I guess.So silly question. Why would someone want one of these? It's not like we can over rev these engines . And you can't monitor the gauge while you're running the car.

I guess. Or like Phill said, for tuningSooooooo after you max it out that first time with the gauge it's kind of a waste after that? Granted they are cheap so I guess it doesn't matter .

Temperature is more improtant though which I can also see.
ok i think ill need a temp 1 too.I’ve had a temp gauge on mine for a while.. not sure how hot is too hot though... I’ve noticed mine seems to run its best around 300-320ish of course that’s at the plug... the cylinder is usually about 100 degrees cooler checkin with an infrared temp gun...
