Graphing RPM was created by jarayner23
Hi

With questions for graphing RPM. I have an earlier Ford with a hall effect internal to the distributor. From the wiring diagram i attached can i use any of the wiring you see to gain an rpm signal? or can i gain an rpm signal from the coil lead?

TIA

Jason

PIP is crank signal. Something specific to Ford is that during crank the CEL will go off showing it’s getting RPM signal.

Thinking out loud always helps me in the process.

Repetition = Revolution

You can use rulers from the bottom left and drag them to where you want to measure. Should display rpm between

Or click measurements, pick channel, change measurement type to frequency, and choose between rulers... and place your rulers. Frequency is pretty much the same as RPMs. Its a measurement per second and RPM is per minute
