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
     for some strange reason :-)

    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.
