Newer ones look at the pulses coming from the Hall-effect sender at the
distributor.  I suspect they abandoned the other method because there are
too many ways the AFM could get jammed in an accident (or otherwise send a
constant signal) whereas the Hall sender only sends when the engine is
actually rotating.
