I ran some quick tests to find which gear was best to climb a local hill. This testing does not come close to meeting the standards in http://ecomodder.com/forum/showthrea...ery-11445.html, but I thought the results might be of interest.

I regularly climb a certain hill. The engine is always fully warmed up, and I normally drive it at 55 MPH in 4th gear. For the test, I also tried 3rd and 5th gears while eyeball averaging the Scangauge MAP and instantaneous MPG displays. The results:

Gear RPM MAP MPG OAT
3rd 3380 10.0 11.7 43 deg F
4th 2470 11.7 13.5 37
4th 2470 12.0 13.2 35
5th 1800 13.9 15.0 27 Unable to maintain speed.
