A wise list of components on the build and fuel burn sounds right.
Have you balanced your injectuon jets? Do you cruise Lean of Peak?
Did you use bonaco brake fluid libes and avoid Nylaflow?

I am going to gather some data for GAMI to see if they can improve how even m
y EGT=99s peak. My number 2 cylinder peaks ahead of the other 5, which
are quite even. I have not been running lean of peak because of that. I t
hink I could get my cruise fuel flow down to about 10 gal/ hr if I got my in
jectors tuned better. Time will tell.
I used real brake lines made up by All Hoses just down the street. I thought
the Vans supplied hoses were junk. A friend of mine has a custom brake flu
id reservoir with a float switch in it. If I can get him to build me one I a
m going to hook it up to a general purpose wire on the EMS and build an icon
for the Dynon EMS screen to display low brake fluid.
I use my middle screen to display engine instruments at 100% in normal mode t
he numbers on a lot of instruments were awfully small and I got a friend of m
ine to modify the file to increase the size of the numbers on a few of them.
He was so successful that I am going to have him increase the size of the n
umbers on the CHT=99s and EGT=99s and post the file here.

Did you upgrade brake fluid to Royco 782. Big reason notvto use 5606.
Your potential fuel burn sounds right. Gami are pros on Continental.
Consider Airflow Performance of Spartanburg, South Carolina for Lycoming.

Thanks for the tip on Airflow Performance. I have a FM 300 throttle body, bu
t I did not know they tuned injectors.
I used 782 for my brake fluid.

Could you define WOT for me. Even considering typos I can=99t figure o

I found it useful to swap my richest injectors with the leanest first.
After doing that a couple times, I found my #3&4 were consistently the
richest. So I ordered 2 restrictors from Airflow that were 0.005 lower
flow size, which got me within the desired 0.5 gph from richest to
leanest peak. All of my EGTs run very close now, although I still get a
very minor roughness when I go LOP. I have thought about trying on notch
leaner yet on those two cylinders, new spark plugs and possibly an
electronic replacement for one of my mags.

Kelly,
I think you may have dropped a zero, e.g., went to 0.0005" smaller (5 ten-thousandths).
Once you get all cylinders peaking at the same time, the smoothness on the lean
side of peak is amazing. I can slowly pull the mixture out until there is no
power being generated. But the engine sounds smooth the whole time.

Thanks for the information. I think I will try that first. Barrett matched the
injectors to all flow the same, so that may not do any good. It depends on how
close they are. The other part of the equation is airflow. Getting the exact
amount of air into each cylinder is probably not possible, so adjusting fuel flow
to match the air flow available is probably the only way to do it.
When I try to run lean of peak the engine starts missing some. Probably because
my #2 cylinder is just too lean when the others get where they should be.

Right. I would expect they probably flow matched the cylinders as well.
I would inspect and clean the #2 injector, then swap it with the #4
injector. That will tell you whether it is the injector or something
else. If #4 becomes lean you know it is that injector. If #2 remains
lean then either one of the lifters on that cylinder is not operating to
spec, or there is an air leak somewhere.

I think I could get my cruise fuel flow down to about 10 gal/ hr if I got m
y injectors tuned better. Time will tell.

In spite of GAMI injectors and reasonably matched flows my -10 was never
really happy running LOP until I swapped a mag for a Surefly electronic

As mentioned above, after using AirFlow apertures to balance the cylinders my IO540
runs smoothly at any LOP mixture, all the way down to zero power/no fuel.
I didnt mention, this is with a pair of Slick mags.
