Of course, fuel injection is safe from carb icing, too.  I big
advantage, but
"dumb" mechanical fuel injection systems like Continental's work
extremely well and are very reliable and can be hand leaned in cruise
to a gnat's whisker of optimum.  I have absolutely nothing against
electronic fuel injection systems, it is just that they aren't really a
heck
of a lot better than a good carb or really stupid mechanical fuel
injection system with a slightly skilled user *when the load is constant*.

I am with you Bill. If you are going to do all that to an aircraft engine
you might as well stick with a rotary.

Chuck,
There are some very sophisticated fi/ign systems coming along right now
(not really FADECs). The GAMI and Prism systems may make all the difference
in the world on some certified type engines, esp on a new fuel formulation.
GAMI (I think) will have pressure sensitive fiber-optic knock sensors (to
vary timing, etc,) and promote lean of peak operation with less stress on
the engine. Braeley of Gami is doing a lot of research. More than the
engine manufacturers. (he makes the Gami injectors).
Check out those two systems. There is a lot of literature on them.
