Congratulations Vince!
One observation about your EIS problems, regarding the fuel flow. What
is the flowscan calibration setting? I started with the recommended
200, which was way to high. I am still tweaking it, but around 170
seems to be a better setting, meaning my flow readings were around 15%
high to begin with. Just something to look at.

Thanks Jeff, I'll be checking that as we burn off the gas.

Vince,
Congratulations on your first flight. I have a couple of question about
your EFIS setup. Do you have the dual GRT EFIS and engine monitor? If
not
whose engine monitor do you have? I look forward to hearing your
evaluation
of the EFIS setup.
George
Dual EFIS screens, no, can't afford that nor have enough panel space. I
have the GRT EIS engine monitor which feeds the GRT EFIS MFD. The MFD
(multifunction display) couples to the AHRS for flight data and the GPS
for nav data (for those who aren't familiar with it).
You can display just about anything you want to see in any combination
that you like.... but it's still not enough when you're trying to look
at EVERYTHING at once!!!
The problems I was having were caused by having a few of the
programmable engine parameters set too low. Gave too many false
warnings.
The units are very nice. I haven't used any one else's, but the GRT
seems to be a pretty good bang for the buck.
Vince

Hey guys,
Thanks for the kind words. Russ, I'll let you know about how it rolls,
but first I've got a few bugs to stomp.
What do you know about low (50psi) oil pressure at cruise. Plenty high
at startup (100psi)?
oil temp at cruise is 200, pres 50 psi, CHTs around 400, rpm about 2200
to 2400. Everything else seems OK. Oh yeah, Phillips 20w-50 mineral
oil. OAT 70F.
Sacremento SkyRanch has some info on their website that says that the cs
and fixed pitch engines use a different oil pressure relief spring.
Mine was a fixed pitch engine converted to CS.
They also talk about the possibility of a plug being left out of the
side of the oil pump. Yikes. I don't think that is likely, but ????
Any comments welcome.
Vince

Vince, I think that you might see a 20 psi increase in oil pressure by using
a straight grade mineral oil, such as Aeroshell w-100 ( 50 wt. ) or W-80 which
is 40 wt oil. Don't know what your climate is going to be for the winter but
I would'nt recommend a multi visc oil for break in. Didn't know they made a
multi visc. in mineral oil.?? I think 50 PSI is too low for cruise conditions.
I'll bet your idle oil pressure ois also very low. billy 026
