Subject: Fuel Flow Oddity RV-12 Rotax 921ULS
I had posted earlier re sudden change in fuel flow readings from a
typical 4.0 - 4.1 GPH to 3.3 on the 'next' flight. After verifying the
fuel flow module was clean, no debris, dirt, I had a good day today -
smooth air - so I could experiment with setting different so-called
"K-Factor" numbers...was 96000 per other RV-12 fliers, and that has
worked well. Now I ended up a K-factor setting of 67000 which is close
to the Dynon suggested starting point of 65000.
Why it changed I will probably never know, but it works and that's it.
