Isn't there also a mod that uses the flywheel, or a plate bolted
thereon to generate the timing pulses?

Did you not get the attached photos Bob?

I got the pictures of the RX8 pick-up plate.  But I seem to recall
there was another way to do it using the flywheel.  I searched my hard
disk for the drawing.  OK, here it is.  You sent this out Jan 19, 2004:

Here is one way of doing it with infrared optics. I have used this for
years in all sorts of dusty conditions.

I missed the flywheel part and forgot about this Bob. Getting old :)
Yep this will work well and if you want to build it and sell
it be my guest. Easy to install and maintain.
It  has also been on the ACRE NL web site for at least five years.

Low cost eccentric shaft position sensor that works on any rotary.


The drawing is for a Ross clutch disk so it needs to be redrawn for
Tracy's dampner plate. Tom Webber can cut these disc out of metal
no problem. It may need more holes to match the number of pulses
per rev that Tracy needs for his computer.
Tom will be back from vacation Sept 6th.

Here is another little trick that we used
on Perry Mick's engine. It is hard to get to the front timing
marks on most aircraft installations while the flexplate is right
out there in the open.
