I need to build a portable, simple, and easy-to-attach engine monitor for logging (each minute) the average engine speed of a large diesel engine (e.g. 4 - 8 cylinders). My device needs to be very simple to attach to the engine, and cannot require manipulating existing engine wiring, fuel lines, etc…
