Yea the auto lets you select third and second gear, but not first. So are you saying downshift when coming to a stop to keep the RPMs above 1600 instead of coasting to a stop in neutral from a distance?

There are stops on my routes, but my driving style rarely require stopping except for stop signs. Yet. This fall I will be going to college in Virginia, and most of my driving (if any) will be heavy traffic, so weight reduction would seem to be key then.

The problem with that is that my dad wouldn't let me do that...and since I'm on their insurance until this fall I'm kinda stuck there.

I think I killed mine prematurely because I started charging devices on it and not always remembering to plug in at night anymore. If I were doing it again, I would go for lithium batteries. More charge cycles. I jsut could not justify the outlay for a new charger when I have a great one for the Odyssey battery, so I bought another odyssey battery (lead acid). My alt delete is probably worth about 3 mpg. Maybe more. Impossible to measure. I have no idea if it is a great ROI measured directly. But if I think about how much I learned and how these mods and my fuel savings encourage me to keep the car, and then if I remember the cost of Prius in depreciation and insurance... well, every mod to "Black & Green" has pretty good ROI.
Out of curiosity, how far can you go on a trip completely alternator-less without going below your 50% threshold?

Since when does an ecomodder care about being cool?
