Hi=20 Guys

In=20 order to extend ground testing and tuning of the engine in 35+C= (95+F)=20 I rigged some water spray onto the water=20 exchanger.
Water=20 temps now stay below 150F even at high load, and to my surprise= Oil=20 temps stayed below 180F (I thought I might have to spray water= on the=20 Oil Exchanger but not required)

I=20 reduced the pitch of the prop to allow a static rpm of approachi= ng=20 7500rpm and without much missing she spun up=20 OK.
I=20 feel like Im starting to get familiar with the EC2 now and betwe= en=20 MODE 2 and 3 and just manual mixture adjustments she runs from= idle to=20 7+K alright.

One=20 observation is that at around 6-7K RPM both the Dynon Skyview as= well=20 as the EM3 fail to read the RPM=20 correctly.
Now=20 they are both taking their sensing from Injector=20 1. 
The=20 EC2 of course gets its trigger signal from the Renesis CAS=E2=80= =99s (main and=20 backup) and there is a mod on the back of the EC2 board that I= took=20 was conditioning of the CAS signals.
Has=20 anyone else had the EM3 read rpm incorrectly at high=20 RPM?
