Default K-Factor setting IO 390

To all Flying RV-14's with stock IO-390,

Anyone nailed down a K-Factor setting for their G3X yet?
Just wondering what you all got. The factory setting is 68000.

Thanks in Advance,

Building RV-14A. #140061
RV 14A N2261 flying as of 7/22/16

68000 is for the red cube. The engine it is used on makes no difference. There is very little variation in the red cubes unless mounted wrong. The old FloScan units seemed to all have different K-factors, but the red cube is 68000.

Default Agree default setting is 100% correct

Double checked mine today to make sure. I used the default setting and its 100% accurate. Have no fear. I'm using Garmin G3X and it tells me how much I have used and then I compare it with the fuel I have just purchased. 100% on the money - have no fear. Happy flying
