which would benefit me more?
trying to decide which would benifit my quest for better economy more. my two options are - -

1. installing cruise control
2. buying a scangauge 2

my car does not have cruise, which i think would help alot with the amount of miles i drive on highway, letting the computer control things. or get the scan gauge so i can monitor things and find out. im not too sure how to go about installing cruise, but i might just call the dealer and find out. if its less then $300 it might be worth it?

what are your inputs? which should i go with?

I would suggest the ScanGauge. Nothing makes the foot lighter then watching the MPG's go down. Plus unless you get the older style cruise control (holds the gas steady rather then the speed) you'll see better results without cruise.

But it all depends on if your foot can handle the long drives.

Definitely Scangauge. Cruise Control will only give better economy if you have extreme problems with your right foot! I "almost" doubt you will find any hypermilers here that use cruise control...very inefficient way to save gas.

Scangauge hands down. Applying a few of the driving techniques here will net you better mileage by far than a cruise control can do. For the average driver who doesn't pay attention to anything and speeds normally, yes, a cruise control will help. For someone who knows what they are doing, the cruise control will actually hurt.

wow ok, i remembered seeing something on a site saying that highway mileage could be increased if cruise was used, by a pretty decent percentage. i had my longest straight ride in my car so far yesterday, about 120 miles each way, so 240miles (or 4 hours in one day) of driving. and it was kinda bothering me that i couldnt just say go to this speed and stay there. but i did get good mileage on the trip regardless, so maybe the gauge is the way to go.

this may be a bad question, but is the gauge accurate? i'd really like to see a running average, and instantanieus(sp?) at the same time if possible.

Mine was within .03 gallons and .20 MPG's for the tank when I filled up the first time to calibrate it.

The gauges I normally have up are RPM, Gallons per hour, Instant MPG's and I also have Average MPG's for the current trip.

oh so you can edit what you see on the screen? that would be great. is the calibrating hard? im not too experience with this sort of thing. im about to order one right now after seeing the responses here.

Not true, at least if you drive in hills - and I don't remember too many non-hilly places in Pennsylvania :-)

Cruise control tries to hold a steady speed, so what happens on hills is that it will be going along at the set speed on the level, and when it comes to a hill will increase throttle to keep the same speed going up, then back way off on the downside. That's bad for FE.

What you want is to "rollercoaster": speed up before you come to the hill, lose a bit of speed going up, then let gravity speed you up again going down the other side. If you get a ScanGauge, you'll be able to see this in action :-)

made the plunge, ordered the scangauge 2. should be here wensday. cruise would have cost me around $300 if not more anyway, thanks for all the help guys, otherwise i would have gone with the cruise probably.

cant wait to get it and share results.

any tips or things to look out for my first time using it and setting it up?
