Took my first real cross-country this past week and checked my Dynon fuel used numbers against actual usage for both legs.
First leg:
Dynon: 7.6
Actual: 6.1
Second leg:
Dynon: 8.1
Actual: 6.5
OK, so this is telling me the Dynon is measuring more fuel flow than is actually occuring. Acording to the Dynon manual, I am to divide the Dynon number by the actual fuel used, which I did, and in both cases this comes out to a factor of about 1.246. Instructions then say to multiply your present "K Factor" by this number, and increase the "K Factor" to the new amount. Here's the rub. My K Factor was already set to 96,500, the number I got from Tony T. and used as my original setting. After multiplication the new factor comes out to 120,239. Oops! The maximum allowed by the Dynon is 99,999.
Not quite sure where to go with this. Will Dynon increase the size of this field in a subsequent release of the software? Should I try to use the "Return" value that is currently set to zero?
