That sensor is just a little coil of wire mounted so that a magnet in the
flywheel passes close to it once a revolution.  It doesn't provide any
static output, just generates a little pulse as the magnet whips by.

You could remove the sender from the engine case and make a reticle of some
sort that would let you sight on the magnet...have to calibrate it by the
other method.
