I'd love to hear more about the prop. Google couldn't seem to help me when I searched for it; is there = a web site showing the specs?

At this stage the prop is not constant speed, just adjustable.
So I could do I similar thing. Choose an Rpm.
Why was the 2100 RPM at the prop chosen? Did you determine this to provide=C2=A0

Our EM3 RPM reading issue appears to be related to inj #1 signal as the reading goes intermittent and low (from memory ~ 800 RPM) and the Skyview suffering the same.

Does your prop have a constant speed controller or is it strictly manual operated? One or possibly two folks flying MT electric constant speed controllers have reported an rpm difference between the selected prop rpm and the actual engine rpm. Mine is very close.

One other thought regarding tuning for 7500 rpm. Initially I had a lot of trouble tuning with the constant speed electric prop. Tracy recommend I run up full power, =C2=A0adjust the prop for 2100 rpm, lock it in manual mode and tune at this condition. This made tuning easier since I wasn=E2=80=99t chasing the changing prop loads. If your prop controller is manual only then you may not encounter the same difficulties.=C2=A0

Hi Guys
=C2=A0
In order to extend ground testing and tuning of the engine in 35+C (95+F) I rigged some water spray onto the water exchanger.=
Water temps now stay below 150F even at high load, and to my surprise Oil temps stayed below 180F (I thought I might have to spray water on the Oil Exchanger but not required)=
=C2=A0
I reduced the pitch of the prop to allow a static rpm of approaching 7500rpm and without much missing she spun up OK.
I feel like Im starting to get familiar with the EC2 now and between MODE 2 and 3 and just manual mixture adjustments she runs from idle to 7+K alright.
=C2=A0
One observation is that at around 6-7K RPM both the Dynon Skyview as well as the EM3 fail to read the RPM correctly.
Now they are both taking their sensing from Injector 1.=C2=A0
The EC2 of course gets its trigger signal from the Renesis CAS=E2=80=99s (main and backup) and there is = a mod on the back of the EC2 board that I took was conditioning of the CAS signals.
Has anyone else had the EM3 read rpm incorrectly at high RPM?
=C2=A0
After balancing our prop, I=E2=80=99m hoping to begin playing with=C2=A0the EC2=E2=80=99s closed loop mode,= and then Timing with new=C2=A0BR10EIX plugs.
=C2=A0
Thanks=C2=A0again Tracy for your gearbox and EC.
