    Sean , what am I going to do with the voltage information? How do I use that gauge to help me out? Just to show me how much I am charging after using the battery on fas?

    It's to keep track of battery voltage when you are fas'ing alot.

    What is to keep track of? Just so I don't use the battery more then I charge it? I guess what I'm saying is what am I going to differently if it goes down? Just allow it to charge more and not allow it to go so low it gets prematurely wore out?

    You don't want to let your battery voltage drop below about 11.6. My SE-R has a high capacity alternator, and never drops voltage while P&Ging at night with the headlights on. But it does drop at stoplights. My xB's weak alternator combined with a small battery mean that my voltage continually drops with nighttime P&Ging. So I have to do a 2:1 duty cycle with the Scion, about 10 minutes P&Ging with EOC alternating with about 5 minutes P&Ging with NICE-on to recharge the battery.

    I plug in with a trickle charger at home any day when I've used the headlights. It costs a lot less than burning gas for the side benefit of battery charging - cents per month vs dollars per month.

    Thanks for the info I was looking for. Making sense now!

    The scan guage was the big motivator in my hypermiling efforts. It helps me keep track of my high score, and like most game players, you are always striving to get a higher score.

    I hear ya there! I am looking at making a grill block ... The cold engine with short trip combo is a tough hole to climb out of. The Aveo is not so efficient when cold...like most cars i'm sure. Love the SGII just knowing what is going on helps change habits so much and the right foot sensitivity

    A grill block is helpful -- so is an EBH. Keep an eye on that coolant temp gauge with a grill block so you don't overheat on longer trips.

    Search the forums for "warm up P&G" -- it is helpful. You want to be gentle with the engine when cold but you can still get improvement using that technique.

    Once again thanks a million Sean!

    To tag onto Sean's comment about Warmup P&G, FAS is even more useful during the first mile or two. Idle fuel consumption is WAY higher, so the value of FAS is much larger.

    I know that my cooling fan comes on at 206F water temp. If I have 2-3 commutes in a week where the final temp reaches or passes that mark, I open up the grille a bit. Just a single time is no problem. The fan is doing its job. You don't want to be running it too much, though, since it uses a lot of juice and there's no benefit once you're above 180F or so.

    Warmup fuel usage (thanks again, Metro):
