Mine was purchased in
Feb of 2002, and I'm pretty sure I don't have the light, unless it's
infrared. Maybe Ed just has good eyes :-) Anyway, my unit has
the plain grey display panel, with no writing on it, and it also has the
larger square box.
As for software, I don't
know if yours will work with the EC-2 or not, but it certainly isn't the
absolute latest version. I'll have that via express mail tomorrow
:-)

just for Todd <g>)
And on that subject, I
just got back from my first flight test when I had time to really check out
the latest version of the EC2 software and I am really stoaked! It has
always worked well but there are a few niggling characteristics that I've
wanted to address. One is the requirement to adjust the mixture
control from lean to midrange when coming down from cruise to land.
Since this is standard practice on Lycomings I let it go up til now but I
knew it could be better. If you leave the mixture lean during low
throttle operation (descending to land) the mixture tends to wander over a
wide range (especially around the stagging point) and if it is too lean,
there is an occasional stumble at certain throttle
settings. The new program code
completely eliminates this and makes the EC2 as close to set &
forget as I had ever hoped. Mixture stays dead on where it was
set regardless of throttle jockying, aerobatics, etc. There are also a
couple of other improvements to the code but this one is the
biggie.
The following excerpt
from the latest setup & installation guide explains the problem
and the fix. Rusty is the first lucky ginney pig, uhh , I mean
customer to get this update. (Will be in your hands on Thursday unless
USPS blows it)
8-19-03 - Dual MAP TABLE
As of this date, the
EC2 now has a dual rpm range MAP table. Simply put, this means that
two separate tables are used at low and high RPM. The dividing line between these
ranges is 2400 rpm. The main
reason for implementing this feature is to allow more accurate mapping of
the mixture under all operating conditions.
It is possible for the engine to
see a low manifold pressure under two very different conditions. The first is when idling. At idle, the manifold pressure is in
the range of 12 – 13” Hg. (18 – 17” if read on a vacuum gauge) When on the ground with a propeller
for a load, the manifold pressure will always be considerably higher when
the engine is running at a significantly higher rpm than idle (typically
1300 – 1700 RPM) The low RPM
MAP table will cover this operating condition and is easily adjusted during
ground operation with the propeller mounted to the engine..
When in-flight, the engine can see a very different
condition. If the aircraft is
cruising at high altitude or is descending at low throttle, the engine will
now be able to run well above 2400 rpm even at a low manifold
pressures. The mixture
correction for this condition may be significantly different than what was
called for at low rpm. This is
the reason for implementing the dual MAP table feature. The selection of which MAP table the EC2 uses is automatic
and requires no action from the
pilot.
