Hi Greg, and others I guess...
Sorry if I offended anyone here. I just have a
problem with off-topic postings, esp of a political nature. It's just too easy
for newsgroup members to address a large number of eager readers with stuff that
may not be germane to the interest at hand. I understand that Greg's posting was
not as off-topic as others, and I'll take my 40
deserved whacks.

When I said I don't really mean to Bob, I meant that
if all was well, I wouldn't be saying this "crap". All is not well in
this climate of "change", and as an airman with substantial investment in my
aircraft, engine, and training, not to mention my freedom, I think this is the
perfect place to bring this "crap" to light.

Greg,
If you "don't really mean to", THEN DON'T!
You gotta know by now that this is not the
place for this crap.

Mike,
I have
developed a system where it is possible to observe and record once per
second about 20 parameters that the EC2 is using. It has proven useful to me to
understand the workings of the EC2 and may be useful in diagnosing what
is happening with your system.
It requires either a laptop with a serial interface or a USB to
serial adapter, or an IPAQ with a serial interface. A voltage level converter which
converts the 5 V EC2 signals to RS232 levels and costs about $20 is also
required. If the EC2 is
accessible and a 1-inch long connector can be inserted between the EC2
and the existing connector, no wiring changes are required. If you are interested in trying
this system, let me know, and I’ll send you a CD with the software and
instructions.

[FlyRotary] frustrating couple of days
I havent flown
my RV since a couple of cases of lost data in the EC2 back in february.
Spent the last few months making a bunch of mods, some suggested by
Tracy, others were things that I thought might increase long term
reliability. Also had to fix leaking fuel tanks in the ensuing
period.
Been working up
toward renewing flight testing. Engine has been running really well for
the last few months. Thought that the problem was cured, though not
clear how. Then on saturday found that once again my B controller
had lost all data. Engine wouldnt run at any throttle setting on B.
Restored the B controller by copying A >
B.
Last night
after work ground ran the engine for about 30 minutes at various
throttle settings and it ran as good as always. Also ran fine on the B
controller.
Tonight after
work I fired it up. Ran fine initially. After about 15 minutes noted
some minor surging at a couple of throttle settings below 2000 RPM. Also
noticed that in this RPM range where the mixture had previously been
fine, my mixture monitor is off the scale lean. Slowly got worse,
to the point that it wouldnt idle at what was previously a solid
1350RPM. Couldnt get it to run at all below 1500, everything between
1500 and about 3000 RPM pretty rough. Everything over 3000 is fine. No
idea what caused this change. I put the airplane away and walked away in
disgust. I'm back to where I was a year ago and I'm just about fed up
with this thing.
