Good question. I would have to think about that hard as OEM ECM's
for piston engines assume a trigger from the 1/2 speed camshaft.
A four cyl fires the the same number of times per rev as a 2 rotor
but the cam shaft trigger is only running at half speed. Seems if
you triggered once per rev of the rotary you might get four
sparks instead of only two out of a four cylinder OEM unit.
Perhaps not. Depends on what you mean by OEM. Is it just
the electronics? I suspect one trigger one spark from the
OEM electronics. So you will need two triggers on the two rotor
flywheel.
Too much for my brain :-)

Paul,
The 3rd gen FD 13Brew uses two magnetic triggers on the front pulley as
oem set up.

Yes I know and I am thinking of going with it. I can do away with
the "crank" angle sensor and have more flexibility of mounting the alternator
on the cool side of the engine. No V belt rubbing problems on the crank
angle sensor. Save a bit of weight too.

Paul are the triggers hall effect, or something else
Also what software do you use to add the comments, lines etc to the
JPEGs you send

I think the 93's and up are magnetic. Tracy might know.
Linux comes with all sorts of free graphics manipulations programs
Gimp is like photo shop but I use xv extensively and Paint to do
the text on photos. At last count Red Hat 7.2 came with over 1000
free programs. I also use a couple of free programs that don't come with Linux
for filing photos.... ytree and xtree for Linux.

Hi Paul and Marc W,
I'm doing the ground work for a simplified ignition system for the
Single rotor engine. Could you give me a bit more info on the 13B that
has the trigger on the pulley? What year, model etc I'd like to check it
out as I like to use OEM when poss. I have a small alternater off a
Daihatsu 3 cyl, its about 4 inches dia and about 5 in long from back
plate to pulley C/L; also it has an internal fan and draws its cooling
air thru the rear, rated at 35 amp. It will go on the cool side I think.

Anything later than 93. Ask Don if you can look at his 98 RX7.
You will probably have to crawl underneath to see it as it is
buried down there. Don my have a 93 or later engine lying around.
This is Don's engine and it could be a 3rd gen as that is
a 3rd gen water pump on it.
