Paul,

I got your e-mail from the guys at Racing beat.  See message I sent them
below, can you advise?

Thanks,

Your question was forwarded to Jim Mederer, Racing Beat's co-founder and
chief engineer, for review. The following is his reply to your inquiry:

   We do not offer an injection system for the application you
describe.  I suggest you email your request to Paul Lamar at
rotaryeng@earthlink.net <mailto:rotaryeng@earthlink.net>.  This is a
website for rotary aircraft enthusiasts, and I believe some of the
participants have done just what you wish to do.

Jim Mederer

   Greetings,

   I'd like to do a simple fuel injection conversion on the 1987
   rebuilt Mazda 13B rotary engine I have installed in my airplane (web
   link below).  I currently have 4 carbs with the associated choke,
   primer and carb heat controls.  For simplicity, more power and
   reliability, I'd like an easy way to adapt an injection system.  I
   have the stock Mazda electronic ignition coils.  Do you have or do
   you know anyone that supplies a complete conversion kit? I'm trying
   to keep costs down so I don't want to have to fabricate or track
   down 'extra' parts for a complete installation.  I also need a
   manual mixture control so I can do the adjustments using the mixture
   gauge in the cockpit from sea level to 10,000 feet (unless automatic
   mixture controls are available).  I plan on keeping the RPM to 7300
   or less since this is the limit for the propeller.  Since I'm not
   familiar with fuel injection installations I'm looking for something
   along the lines of "Fuel Injection for Dummies".

   Thanks,
   Oly Olson

That is a cool looking airplane you got there Oly.

We are working on a very simple constant dribble mechanical system
design. So far nothing has been made except the p-port slide
throttle but if you want to try it out on the ground first you
will get plenty of help on  this news letter. Just ask a question
and our world wide collection of people putting rotaries in
aircraft can help. Lots of people are flying with Tracy Crook's
system.

Tracy Crook makes a dual EFI system for rotaries
in aircraft. I see you already know about Tracy from you web site.

Megasquirt is another option.
