I have two fuel flow red cubes. One on main/delivery hose. One on return to tank hose.
Followed Dynon instructions, I provisionally set both for recommended Rotax 912ULS pulses (70000??).
Over several flight & refuels, to same level (full), I made adjustments to number of pulses on the main/delivery line cube and now have good level of accuracy - fuel used and fuel remaining.
I did not adjust/alter the return line provisional setting. My understanding being, whatever fuel flow it registered, would be subtracted automatically from the main fuel delivery line flow.
BUT! my in flight fuel flow seems to be high by about 7L/minute - how can this be?

- Should I be adjusting the return line pulses?
- If so, will the adjustment to the return line pulses, effect the main line pulses accuracy?
