Thanks, all. This is exciting, and I appreciate the helpful folks here on the forum. I especially like the quote I saw somewhere, we're trying to help people do the best they can do with what they have.
I have gotten two fill-ups so far: one was more highway driving, where I got 18.2, and the other more city-ish, where I got 14.4. The 18.2 I think was pretty good, being above the EPA for highway (17). I was doing some techniques that I vaguely remembered from reading some car magazine years ago - cruise control, gentle pullouts. I am looking forward to learning lots more from you fine folks.
I like the GameBoy idea
but that makes me wonder about that ScanGuage. The idea of constantly-flashing numbers that you are looking at seems, well, a little unsafe. Not that I'm never distracted - the nav system is plenty distracting. In fact, that's what I'm concerned about
: I can see myself being mesmerized by the numbers.
Also, is there a place that tells you how to use the ScanGuage to improve your gas mileage? Also, my car has an MPG display on the dashboard but it is, well, strange. It reacts veeeerrrrrrryyyyyy slllllloooooowwwwwwly ... perhaps changing once a minute or more, and if then only like 0.1 MPG at a time. When I bought it, it was showing 3 MPG (the salesman said it was because it was idling, which seemed reasonable at the time) and it has slowly crept up to showing 14.4 right now. Does anybody have a feel for whether this is a symptom of simply a problem in the display itself, or if the data it's reading is actually updating that slowly. I assume that display reads the same harness as the ScanGuage does; so if it's a data problem, it seems to me like the ScanGauge would be useless.
Thanks again for all your support and friendliness. I really appreciate it.
