Subject: [FlyRotary] Re: inspection and
first flight ?
I expect to hear tales from Rusty stretching his wings today, either
that or some cussing about injectors, etc. :-(
Great
news about the inspection Todd. Congrats!
As for first
flight reports, I wouldn't expect to hear any today. I spent a
long day yesterday completing little items on my to-do list, and
whittled it down to only two remaining. One is a 30 minute
job, and the other (tuning the engine) "should" be a 15 minute job. My
plan for today, is to finish these items, and call it quits for the
weekend. My airport is under (900 ft) the class C airspace of Whiting
Field, which is a large Navy training facility. Fortunately, for
us, they're shut down on Sat, and most of Sun (until about 3 pm), so the Class
C portion goes away. The first flight will take place when Whiting
is closed if possible, so next Sat will be the target date. That
gives me a week to think of any remaining items I might have forgotten, and
think through the first flight some more.
As a side
note, one of the items I had to do yesterday was to bend my oil dipstick
shorter, and fashion a door in the top cowl to get to it. When I first
fit the top cowl, I just drilled a round hole so I could insert the
dipstick. As it turned out, the factory stick extended just above the
cowl, and I gave some thought to just leaving it like that. I finally
decided that I had to make this right, since my "buddy" Bob (webmaster for the
local EAA chapter, who also has a key to my hanger) would surely put a picture
of my dipstick on the web page. He's been bugging me to put the top cowl
on, and I'm sure that was his reason. I think he'll be disappointed
:-)
I already
know that the new EC-2 chips work on the "factory 0" default
settings, and I'll start out today with the new default settings, which are
Tracy's actual engine parameters. Assuming all goes well, I'll verify
the new tach at high rpms, and see what my latest static RPM is, now that I
set the prop to 15 degrees. I'm shooting for at least 5000 rpm
static at 30 inches MAP. All running today will be
done with the cowl completely on, so I'll get to see how the temps
behave. It's mighty hot, so it should be a good test.
Cheers,
Rusty (Fat
lady not singing today)
Sounds good
Rusty & Todd.
Rusty, Keep in mind that the new engine MAP
table loading option is based on my 15" Hg MAP stagging setpoint. As you
have already discovered, your larger injectors require a higher stagging
setting. After thinking about your test results, I'm thinking
about making the default setting up around 19" Hg. instead of 15.
This should work for both turbo and non-turbo engines and make setup around
the stagging point easier.
I'm
going to try this on mine tomorrow and I'd suggest all users do the same
if they are having any difficulty getting mixture smoothed out at the
transition point. To do this, start engine, set Mode 7 on EC2, run
engine up to 18 - 19" Hg MAP (11" Hg vacuum at sea level if you are using a
vacuum gauge instead of a manifold pressure gauge), then hit the red (lighted
or un-lighted) program store button. You will probably have to re-tweak
your MAP table but overall results should be better.
