Neck deep in finishing up a Dynon HDX-based retrofit.
Have gotten to the point of entering data into the Dynon HDX for the fuel flow and K-factor.
Here's the issue:
There is no tag on my fuel flow transducer indicating the number of pulses that I need to enter into the Dynon. The previous owner (or builder, not sure which) had a sheet of paper in the manuals/docs where he had hand-written the K-factor number, but there's nothing on the bench test tag number.
Now, he had an FP-5 fuel computer and transducer package, and, reading those docs leads me to believe that the flow unit is a Floscan 201 based on how it looks and what I can find online. Like I said, I don't have the tag, but I do have the K-factor number. The transducer is the same from legacy and it was pretty darn accurate when it was tied to the old FP-5.
It seems like the K-factor for these is the first three digits of the pulse number, so the K-factor number I have is "850" - which means I should potentially enter 16-85000 into the Dynon config? Would that get me in the ballpark?
I'm not sure what else to do here other than potentially replace it with a known-good-bench-number unit, but I hate to do that since I know the unit works. I just don't have the baseline number to enter into the Dynon HDX.
What would you do?
