I installed an Dynon EMS D-120 in my RV-8, but I can?t get correct RPM readings from it. I tried differents configuration (as manual said), but if I get 2600 RPM full throttle, I get a ralenti of 1200 RPM. I think it is wrong, because ralenti value for my engine would be 600 RPM aprox. My engine is a Lycoming XIO-360 180 HP with constant speed propeller. Suggestions??
 
Yes I already did it. But with setting in 1, it reads between 1200 to 2600 rpm, and with setting in 2, it reads between 600 to 1300/1400 rpm full throttle...I don?t know which one is correct, or both are wrong??
