Graphing RPM

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

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

Okay sweet. found it and got a waveform. whats the easiest way to convert this to an rpm and graph it?

the following are waveforms are from the PIP wire of the TFI ignition module on the EEC-IV (4) ignition system. is there a math function i can implement with pico automotive 6 convert into rpm?

also a question on the above waveform would i say the 5 wider waveforms would be ther reluctor then what is the narrower waveform represent?

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
