The bottom line is not that the noncertified engines get a free pass,
or they shouldn't, but that:

1. Certification of the engine, is not required of aircraft with
Experimental/Amateur-Built C of A:

2.Is of no benefit except you get a shorter fly off period:

3.The commonly available choices of certificated engine unless you
can buy a new PT6A-34 are simply ridiculous from any reasonable
standpoint.

I believe if you want a certified engine perhaps you ought to have a
certified airframe to go with it. If type certification improves
powerplants, doesn't it improve airframes as well? To think otherwise
is schizoid, particularly in a world where you can buy easily
rebuildable certificated aircraft and an overhauled museum piece and
prop to match for less than a lot of people are putting into kit
planes.

And as far as the electronic issues go, I don't want FADEC on any
engine, certified or not. I would rather have mechanical FI or a float
bowl carb and a one mag one electric system (like Franklin so
intelligently used as did Shaky Jakes). Actually the most reliable
engine control system in the world is PT Cummins Diesel injection but
that's another story entirely. All hydromechanical.
