Not sure where this best goes, but since it's a report on the PCM update, I pick here.

I show results in two flavors, mileage and fuel consumption. In each case, I plotted data for a 15.5 mile commute, taken both ways every day, on sparsely-traveled 35-45MPH-posted roads at about a 30MPH average speed. 5 "stop" signs and 12 lights. I make a point of driving 0-10MPH over the limit, with most time spent in the upper half of that range. I have removed any rainly days, and limited the temperature range as the recent dips below freezing have resulted in a non-linear pattern that I believe includes more than variation due to the PCM update.

 

Based on 40F-60F data (linear range?), I am seeing a +5.4% change in mileage and a -5.1% change in fuel consumption at 50F. Now, for some expressway driving!

 

HAve fun,

Frank
