This is not by any chance auto motive modification even though you dunno what I had in mind.
Having said tht, I was wondering about this idea last night.
I wanted to read the engine RPM without taping into the harness.
I believe I can take the pulse by placing a coil on the spark plug wire.
The high voltage can induce enough voltage in the coil to make a pulse each time the coil generates a pulse, right ?
Question is what is the pulse count for a 4 stroke engine.
How many pulses would be produced by one engine rotation?
