Don't forget to send me the model number of the Ford ignition module for
my Renesis that you mentioned at Sun n Fun. I can't believe 22% BTC is
enough spark advance but I will try it once I get set up. Karibian
OK here is what I have.

Hi Paul,
I was looking at this unit with some interest. I have found another
unit that we can use two of and i would like your advise on it.
I was thinking of using two units and firing by two senders on the E
shaft for each rotor and having two triger units for trailing and
leading spark plug. What are your thoughts on this. the Ford unit also
looks good. The site for these units is http://www.msdignition.com/sci_6.htm
Ian came to our clubs fly in this weekend and had his machine
cooling running great. he has changed his duct to to what the info in
Kays and London book recommends and had instant success. He got
another 5 knots out of the plane through the loss of cooling drag. His
radiator is quite small compared with what I have in the mustang but I
have the shape right after much testing so I will have a problem
getting it warm. My radiator is 3 times the capacity of Ian's.
I dont think I will have any problem with mine. I would like you
opinion on the ignition system as. Regards Don
PS you are welcome here if I am home when you plan to come. You may
see a rotary powered Berkut going together.
Regards Don

Two units is always good as a back up.
MSD has some good stuff but I am not sure which model number
works best for our application. They give good email support so try asking
a few rotary specific questions. Also ask for the rotary installation instructions
pdf for a clue on which one is the easiest to install. This pdf file mentions only
piston engines.
Interesting data from Ian about the Kays and London diffuser. Perhaps it responds
the same positive way as the Kuchemann and Weber diffuser that Al Gietzen recently
installed. In theory the K & W diffuser can double the pressure on the front of the
rad. For you new people I wrote a book on these subjects called How to Cool Your Wankel
available from Mazdatrix. And AC Spruce.
Thanks Don for the kind offer. We will take you up on it for a day or so.
We will rent a car and drive up and down the west coast seeing the sites as
well as visiting all our friends in the Perth area. Perhaps we can organize another
rotor head dinner in downtown Perth. I think we may have one or two new members.

Paul,
I just received my Megasquirt V3 kit and am assembling it. The hardware
is a no brainer for anyone who is assembling an airplane. The software
setup looks intimidating but only because of the tons of information
that has been posted. Reading through it all was educational and there
is no programming involved. Compared to learning to use a new graphic
software program MegaSquirt is easy. It is mostly inputing numbers into
tables.
Several people have successfully adapted a rotary 13B to work with
Megasquirt so the parameters are available as our lots of helpful people
in forums for hand holding if necessary.
For those that don`t want to fool around with a kit there are now PCBs
with surface mounted devices all ready made up. This is with the bigger
V-3 board as well as the tiny Micro-Squirt board which will be out
shortly.
One post I read describe a set-up similar to what Don has suggested. In
short two timing wheels and sets of sensors, hence NO wasted spark. He
used two Ford EFIS units. That was four years ago. Of interest he said
the engine had over 295,000 miles on it.
Corvette coil-on-plugs, LS-1 seem to be very popular. Questions remain
how hard we can drive the plugs, and if split timing firing of the
plugs is even necessary. If so would is it benefical in at 6000 rpm?.
Another option is to use the newest version of Megasquirt code that
supports external routers so we can pretty much set up the ignition
system like we want.
I like the idea of being able to control the ignition as well as
injection in each rotor independently.
