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.
