Luke,

EFIS Range is a rotary switch with 6 positions not a rotary knob so try P04_005_KN6 = 0 for the first position: incrementing or decrementing for each position. L:KLID not required.

I use a Goflight MCPPRO and EFIS along with Goflight Interface Tool (GIT) from Pollypot Software which makes life a lot easier and have all buttons, switches, rotaries and displays all working correctly.
