It's an eddy current probe, there is a mount sticking out from the engine back
plate, it counts two small tabs that are on the back of the fly wheel.
I got it from RS Components

Hmm, hall efffect not supplied? What is that a $2 transistor. I saw a pic with
the sensor installed on a Jab site. I ass-u-me-d that it was supplied.
I assume there is a mount for it on the engine?????
Thanx for all the pullup and protection advice. I will definetely be taking it
all to heart.
Glad to hear everything is just pots, the oil temp and pressure.
What is a vdo?
I hope to open my engine box next week and am beginning to plan for the microcontroller.

Hi Bob-
Yes, the ring gap being closed up, and perhaps the addition of the
Electroair direct fire ignition system, but I'm betting on the ring gap.

My CHT's are comparably high, because I've attached my probes
directly to the head instead of being up in the airstream. Take a
look at where the reading area of your spark plug probes is, and
you'll find that you are not reading CHT, but rather the air
temperature NEAR the head. In my humble opinion, Jabiru should have
done this on all their engines, and we wouldn't have the problem of
putzing around with the spark plug washers every time we change
plugs, and get a more accurate reading of the actual temp of the
head. My heads run around 340 degrees F. EGT's vary from mid-1200's
to 1420 for the highest.
