Mike;
Your experience of the problems is quite
different than mine, so the ultimate cause is probably different as well.
My B controller was always more stable than A; so when things changed, I could
switch to B. From about hour 3 to about 15 I flew mostly using controller
B while we tried to figure out what was going on.

Corruption of EC settings
No I was not aware that you went
through similar problems. I was off this forum for about 4 years during which
time you completed your project and flew it.
Your experience seems similar to
mine. If anything yours sounds more severe. Looking back over the past year and
a half since I had my first engine start, I've realized that I've gone through
very long stretches without any of these problems. In fact the first 20 hours
of ground run time I had all of the typical (many self induced) tuning issues,
but no cases of corrupt data that I could identify. It wasnt until after
my first flight that I had it happen. Three times and then I grounded the
airplane. In the subsequent 4 months and an additional 5 hours of run time on
the ground there were no instances of corrupt data until this past weekend when
I started prepping to resume test flying. Since then in about 2 hours of ground
running I've had 4 instances of corrupt data. Three cases where it wouldnt run
on B, but since I have no way to know whats loaded in B I dont know what
exactly is happening there. And one case of the staging point on the A
controller changing to 12".
I could probably resume test flying
as long as I remain over the airport. But given my phase 1 test area and the
terrain I'd have to cross to get to something landable I wouldnt want to
venture too far from Brown Field with it like it is. Whats the point of having
a backup controller if you have no confidence in it?
My EC2 is also an early one. I've
had it so long I cant recall when I bought it! So as you say, newer units may
not have similar issues. And of course in my case since the problem is
unresolved at this point, it may still be an installation issue, though at this
point I'm stumped as to what that issue may be. I agree that the EC2
is the best option for the application. When not having these
problems, the engine runs great. Which of course is part of the
frustration - with it running so good why cant I go fly it and have confidence
in it?
No opportunity to do any further
testing today but hope to get back on it tomorrow. I've sprung an oil leak
(previously thought repaired) that I need to fix before I can start the engine
again.
