OK I have my gauge and I'm using it to find out what works best on my Fit.
1st
Short shifting @ 2000 (as I started doing) with any acceleration is NFG. As I kind of suspected it loads the eng and the mpg is 12 to 15. Raise it to 3000 and it's well over 20mpg as you go up in speed. I will try more RPM's and find the best shift point.
2nd
It's true when you see a light and want to slide in with least fuel (with eng on) coasting in neutral is 0.25gph no A/C and .4 w A/C. Lift off the gas in 5th gear and it's 0 gph till you stop. real time MPG calc goes to 9999
3rd
It's 80F here, but when the eng is cold and not up to temperature the combustion controls does go into closed loop very fast. In fact, in less than 15 sec's from over start on an night stop. This is long before the cold eng light goes out. Was wondering about that. Bottom line, don't wast a sec idling to warm engine, if you want to save gas. No idea how that is in very cold areas of the world???
info bud
at 45mph in 5th steady cruse the Fit gets 50+ mpg
HAs anyone else got some stuff to offer.
I'd like to try a taller tire some day. Anyone try that and document the mpg change?
