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.

        lines between sentences

       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).

        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.

   This picture shows a magnetic pickup sensor, similar to ones used on the flywheEl of industrial Diesell.  They generate a sine wave, to appropriate decoderived,  usually inside the tach. Some say they are hall effect. I am doubtfully,  not looking at all similar to the hall effect sensors I have seen. A metal disc goes between 2 sides of the hall effect. Most always on this topic, I need to be educated.

   They do make some of them that look like that.

   Paul Lamar

   But no magnet in the ring gear teeth, how they do that?

   Barry?
