Rino,
Are you saying that you SHOULD or SHOULD NOT stop and start the engine
with the switch in position nine?? I assume that you are only talking
about when you are trying to change the programming??
Tracy??

I had a memory loss similar to yours on the A controller a
few times when I was programming the mixture. I then realized that
it appened when I left (forgot) the push switch on position 9 of the
controller, stop and start the engine. Stop and start the engine while
the switch is in position 9 instead of 0. Never happened again after
that.

I got my staging issues under control by following
others advice and moving the staging point up in the RPM range.
Unfortunately I have had two random cases of the
EC2 loosing pieces of its non-volatile memory. The last case was the worst -
the entire B program appears to have been lost. It would not run at any
throttle setting on B. Fortunately I found this on the ground during a preflight
runup. Copying A to B restored the program and the engine runs fine. I'd
sure like to find something conclusive to indicate what happened, but this was
2 random events in over 20 hours of engine running and I have no idea what
triggered it. I've exchanged emails with Tracy and he says its likely a grounding
issue. So I've spend the last month going through all of my wiring looking for
some sort of problem. Havent found anything on the ground side.
As mentioned previously I do have a little hum
noticeable in the headset when the alternator is energized. I was preparing to
look into this - dug out the O'scope and everything - when the stupid fuel
tanks (both) decided to start leaking 1 1/2 years after I first put fuel
in them. Just about have the leaks resolved and time to get back on the
electrical. If I can get rid of the hum then I'll probably still be looking at
a couple of hours of ground running before I'm willing to fly it again.
Intermittant problems suck. Thing is you never really
know if whatever caused it has somehow been fixed unless you actually find an
obvious smoking gun. Not clear to me that I am going to find that.
I've been hesitant to post about this unless/until I
had something conclusive. Didnt want anyone to leap to the conclusion that
there is an EC2 issue. I assume that whatever it is, its particular to my
install.

Mike,
What kinds of problems are you having? Looking back over your
posts, it looks like you were having problems with the staging set right over
your approach power setting. What else is happening and have you moved
the staging yet?

OK, I can accept that. It may seem from some of my
recent posts that I'm down on the rotary - not the case. I just want to
make sure that we paint a fair picture which is frequently not the case on an
enthusiasts website.
I'm probably a little negatively biased right now
having done my first couple of flights, come across a couple of problems that
are unresolved, and am currently grounded. I really want to fly this thing
again but havent had as much time as I would like to fix the problems and get
it airworthy again.

I understand and agree with
what you are saying regarding the experimental nature of these one off
installations. But if you dont compare them to the norm, what do you compare
them to? I guarantee you that is what the LyCont flyers are comparing them to
Mike;
Sorry I wasn’t clear – I
meant it wasn’t a fair comparison during the first couple hundred hours,
while we are still in the debugging phase. After tha, go ahead and compare.
If we can get to some comparable reliability level in that short a time,
compared to their 100’s of thousands of hours, we’re really on to
something.
I’m actually not an avid proponent
of alternative engines. I just happened to have chosen that route, and
it’s been a rewarding challenge; and working well.
