Trip A, B numbers decoded.

The way that Trip A and Trip B meters increment by 0.3 or 0.4 mpg intrigued me from the beginning. It was easy to figure out that the Honda computer was dealing with liters instead of gallons because the conversion of 3.8+/- liters per gallon was familiar, having driven a ways in Mexico. I set up an Excel spreadsheet with one column for FE in m/liter, starting at 5.1, 5.2, etc. Up to 31.9 m/liter. Then in the next column, I multiplied those values by 3.785 to get mpg, which may run to six digits. The next column truncates the mpg to one digit past the decimal (not the same as rounding). And what you get is the series of numbers that Trip A or Trip B displays. Exactly. From 19.3 mpg for 5.1 mpl to 119.9 mpg for 31.7 mpl. I haven't observed all the numbers, but with spouse's help we've recorded about 80% of them and they all match. Has anyone seen 91.5 rather than 91.6 on their display? It's (91.5) the English equivalent of Honda's 24.2 mpl. OK, the procedure won't predict 120.0mpg, but there's probly another reason for that one.

It's funny what kind of activities being retired leads one into.
