Just having trouble getting my = wideband sensor working properly.
What OAT were you = working in.
I=E2=80=99m now going into 100+ would = have been nice testing in <70 OAT

Hi Steve, every installation is different; = however, I can post my numbers and methods.
First, I have excessive = oil cooling (2 coolers in bug-eyes) and marginal water jacket cooling (1 = radiator angled below engine).
With this setup I can run almost = indefinitely when stationary from 2000 to 3000 rpm, this range expands a = lot if taxiing.
My tuning method was to tie aircraft to trailer = hitch on my SUV then following the EC2 Manual:
1) Mode 3: Slowly increase = power to 24" MP and set fuel-flow for mid O2 sensor reading.
2) Mode 2: Slowly reduce = to idle then adjust idle for mid O2 sensor reading.
3) Mode 1: Increase power = to just UNDER Staging - adjust this BIN value.
4) Mode 1: Increase power = to just OVER Staging - adjust this BIN value.
5) Mode 1: Increase power = to WOT - adjust this BIN value.
6) Read/Record EC2 MP Table - manually = adjust BIN values between steps 2 & 3 for smooth = transition.
7) Read/Record EC2 MP Table - manually adjust = BIN values between steps 4 & 5 for smooth transition.
8) Repeat steps 2 to 7 = until comfortable.
9) Fly the airplane and use mixture control to = adjust any anomalies.
10) When comfortable, fly the airplane and use = Mode 9 to tune out anomalies.
11) Repeat steps 2 to 10 until = satisfied.

Hi Guys
For those who have tested and flying = their machines.
I=E2=80=99m finally about to ground(stationary) = test our Renesis 4 port powered Glassier Super IIRG EC2, EM3, RD1-C = Electrical Pitch Prop.

Your wisdom, experiences, = testing procedures to carry out would be very much = appreciated.

Particularly whats = reasonable to expect from my cooling system (modelled of Tracy=E2=80=99s = RV8)?
Now I=E2=80=99m sure it depends upon load and = OAT, but what where your experiences?
How long could you guys run before = overheating etc?
Did you provide any supplemental cooling to = extend this testing?
I=E2=80=99m thinking of putting a water mist jet = into the cooling duct/s to see if it significantly increases cooling and = time testing.

Appreciate you = feedback.

Sincerely

Steve Izett
