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.

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!

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.
