OTOH, if it really does switch to a rolling average at some point I guess it is tracking FE in some units.
I'll stick by what I said, tho', recalculated--for the OP's FE to jump up from 26.9 to 30.3, the data packets that
fell off the calc had him burning 25 gallons of gas w/o going anywhere.

The consensus for the ave on the FEH is 2000 data points, one every minute, so 33 1/2 half hours of 'running time'.
I agree with you, unless there was an accidental re-set, unseen by the driver, the average numbers are wildly skewed. If there had been a re set, and there were only, say 20 data points, it doesn't take much to cause a big swing.
