I'll think of more, but please add whatever you feel like or mods you would like to see busted/confirmed.

Also, I saw an older Mythbusters last night that I hadn't seen before. They tested AC on vs windows open FE. I think their testing methods left a lot to be desired and they should have run it more than once, plus they only tested at 45 mph due to safety conditions on the track. Windows open won by traveling an extra 30 miles on 5 gallons of gas. It's a large enough margin that I'm certain it would be fairly consistent, but I'd like to see the same test at higher speeds (and swapping methods per vehicle, and repeatability, etc).

Eventually we'll streamline this into an actual wiki for the site.

lol there goes your thread

just ask

Nah, you suck, I'll add something right now, I think, if I can find it.

I added some stuff, as more things enter, organization will as well, :p

EOC = Engine Off Coasting (user diamondlarry)

CODFISH = Coast On Demand Forced Ignition SHutoff (user 95metro)

ICE = Internal Combustion Engine

Thank you, sir, I will edit up some stuff right now.

EV = Electric Vehicle
HPV = Human Powered Vehicle
ECU = Electronic Control Unit
VSS = Vehicle Speed Signal
NiMH = Nickel Metal Hydride

There should be a howto for EOC restarting, the clutch start. I've done it a few times now, but I still smell fuel, which can't be good, and it takes a while. I'm obviously not doing something right.

Um...CODFISH was mostly a joke. However, I guess it has been used here and there now so it may as well stay for reference.

Wow do I ever feel special? I ask and **poof** glossary.

Thanks guys!
