Paul,


   Can the RX-8 sensors work in a
   reverse
 logic scenario?

     Use a
 solid metal trigger wheel
   with a hole
 instead of a tit,

     The
 voltage would be high until
   the sensor
 saw the hole.

     Use an
 inverter chip before the
   CDI or MaxiMite
 permitting
     triggering on the
 negative
   pulse.

     Probably adds more issues or
   trading one set of problems for
     another.

   That is not how they work. They work on
   a change in magnetic

 properties. They might work with a
   hole.
 Make a test plate
   and chuck in a drill
 motor. If you have
   a scope you will see
 what
   the pulse, if any, looks like. Take
 a
   picture of the scoop face.

   The best thing is get a
 water jet
   company to make the plate
   as you need the elongated mounting
   holes for timing adjustments.

 inserting blank

 Paul,
 This is what I use to time my combustion
 pressure tester.
 I used an optical sensor at
 first but it was very intermittent. When we
 switched to the Hall Effect sensor HET it
 became very reliable.
 There are slots cut
 into the standard 3rd gen timing wheel.  (The shinny
 surface was used for the optical sensor).
 Barry Bordes


   Yes. They are easier to
 mount. Much much smaller in some cases. This
 one looks
 about the same or
 larger than some wheel magnetic sensors.

Paul,
I actually like the idea of mounting it on the output end of the eccentric shaft like Mazda uses on the race engines.
Plenty of room and protected.... you also have room for a second back-up set like the second mag theory.
