Just wondering and please forgive me if this is old territory but I'm a noob
 here and a recent convert as i was looking to try to adapt fords 2.5l v6
 Duratec engine for my anticipated Midget Mustang. I've probably given up on day
 dreaming about a pair of Ford big blocks for my ultimate fantasy
 P-38. I'll start my 3 rotor compound turbo'd/supercharged rotaries instead.

 You guys just have too many good ideas here, anyway back to my question.
 Are the mega squirt kits suitable to our uses here or not. If not is there a
 schematic around somewhere for an ecu AND maybe an emu. I have been an avionics
 tech for about 40 years and an A&P for only the last 4 years. I  still like the
 smell of solder fumes so I must still have a few brain cells left to murder so
 building my own electronics still appeals to me. Well TIA for any input.

 The Mega Squirt is suitable and probably the best bet if someone
 wants to build their own computer EFI.

        G'Day Paul,

From what I can recall opinion seems fairly evenly divided on the merits of
carburettors and fuel injection, however the importance of carby heat seems to
get ignored and I haven't noticed any provision for it on any of the
installations I have seen here. Are rotaries immune from carby ice, or have i
missed something?

The FAA will not sign off on a AC carb here in the U.S. unless it has
carb heat.

I have never brothered to draw something up as it is quite simple
to copy certified aircraft carb heat designs. God knows we have plenty
of exhaust heat to work with :)

Paul Lamar

Not sure that is true. Just looked at an RV-12 -- no carb heat on the Rotax 912S.

Joe Spelz

That is dangerous. I am not familiar with that engine.
It could be hidden. Due to evaporation of fuel the AC intake
manifolds generally run ice cold.
