RPM reading "times 2" after Fly EFII install

[tucsonphil]

Did my first engine run after installing the Protek FlyEFII System 32 in my RV-10. I have dual Skyview HDX's and the RPM is showing double the RPM of the EFII display. For example the EFII display shows 1000 RPM, then Skyview displays 2000 RPM. Probably just a setting but I can't find it in the install manual. Any ideas how to fix this?

Thanks,

Phil in Tucson

You need to change the PPR ( pulse per revolution) in the EMS setup page to either 3 or 6, eg if you have it on 3 then change to 6 or vice versa per
SETUP MENU > HARDWARE CALIBRATION > EMS CALIBRATION > TACHOMETER CALIBRATION.
