If you are using the larger injectors in
primary position (like anything above around 460 cc/min) then idle can get
to be a bit on the rich side, lowering fuel pressure can help out on this
end - but the reduced flow on the top end can cause leaning
problems.
I fly with 460 cc/min injectors and find that
43 psi gives me the best all around performance. Larger injectors may
do better with slightly lower pressure.

First Start
That's interesting. When I was first starting
to test my rotary I had to back the fuel pressure way down to get it to
run relatively well. I'm backed off as far as the Aeromotive regulator
will go and indicating about 33psi. Now that things are running better
maybe I should try to bump it back up a little. I think Dave Leonard told
me he had to go down on pressure as well. What is the consensus
opinion?
Still some little tuning issues but it's
running well enough to taxi around now. Runs great above 3000
RPM. Maybe a revisit to fuel pressure will help.
Need to find a DAR and get this thing
inspected/flying!

Start
Saturday
with the help of Mark Steitle I was able to start my renesis. Had
to run higher rpm's to keep to it running. Wideband O2 showed
lean at lower rpm's. Today after adjusting the fuel pressure to 42
psi (was 30 psi) I was able to idle much lower. My Advanced Flight
System EFIS\ engine monitor fuel injector circuit is not putting
out a tach signal so no idea on the actual rpm's. Two primer clicks
and it starts right up.
