My truck gets 68mpg, when I'm driving downhill at 25mph!

(And 0mpg when it is sitting there idling.)

Yeah. I've driven cars with instant mpg readings that do that. Mom's Caddy switched from instant to average and it's funny to see the proclamations of the instant reading.

My car uses only the avg so it doesn't fluctuate like that, but I really have to practice hyper-mpg techniques to get it to go up even 1 whole mpg once it's gotten past the half a tank point.

Sounds like the Scangauge has arrived. I'd love to see.

I think now you're ready for a flash tuner. Check out some recommendations on some of the F150 sites--Ford Truck Enthusiasts at ford-trucks.com is one I watch on occasion. Don't expect a high level of discourse or even literacy, but you'll be able to tell who knows what they're talking about.

Basically, a number of folks dba tuning firms have developed custom maps for altering both engine and transmission parameters for different conditions--many maximize power, some torque for towing, but others max economy. These are uploaded with a handheld tuner that plugs into the OBDII port. SCT is a popular one; I'm sure you've run across it already. You'll get a package that combines the tuner with several new maps. The nicer packages will include a map or two for your unique needs and a dash mounted switch to change among them. Otherwise you upload them one at a time.

Lemme look around in the other forums a bit; there are some nifty programming tricks one can do with a ScanGauge, called "X-gauge" or something like that, that can really augment the stock ScanGauge's utility, depending on what info is being sent out the OBD-II port.

*All* motor vehicles get 0mpg when they're sitting at idle. You have to be actually moving to accumulate miles, right?

Duh. But it's amusing nonetheless.

Hee!!

Oh; I found a PDF file with an assortment of Xgauge codes for extending the functionality of a ScanGauge (assuming it's version 2 of the gauge). If you're interested in dorking around with it, I'll email it to you. Lemme know.

It is indeed a version 2. It came with a document with a bunch of extra codes like that, maybe the same one. But it would be worth taking a look at what you have, just in case. Thanks!
