well i climb the cajon pass all the time.
it goes from 700ft to 4200 ft in 12 miles so its a high speed climb
i have to get in the truck lane to climb that pass if i want to stay in lean burn
it is tough to keep the car in lean burn.
its pretty much engine load like tom said.
you can get in to lean burn in second 3 4 5 gears.
to be honest with you it seems to coincide with the shift light.
if you are climbing a grade and you keep the shift light on it stays in lean burn.
when it shuts the shift light off it feels stronger and lean burn is not on.
i don't shift when the shift light advises me to any more.
i sometimes have to go 35 mph to stay in lean burn
and it still gets over 47 mpg. before i used to climb as far as i could in high gear and then when i needed o downshifted. ever since i keep lean burn on it really shines in the FE section
