Right, so it's not really quite that exciting, but I did have to monkey around with it a bit yesterday. I'm liking the extra guage functions on it as much as the economy related stuff.
Anyway, it mounts fairly conveniently in the Mazda5 above the steering column without the use of the sticky tape. The OBD port is located in a pocket just above the hood release which is left of the column. From there the wire simply stuffs easily between the dash and column cowls for no more than 4" of exposed wiring before emerging just right of the scanguage which rests comfortably on top of the column cowl in plain view. I took a couple of fairly high-G corners with it there and it didn't budge, so that's a nice plus.
First impressions are that it's worth the money if for no other reason than to tell us it's time to start the car after sitting in it too long listening to the stereo. It's also obvious after a few quick trips to local stores that it will be difficult to improve mileage around town, save for glides which easily bump economy up from 22-23 to 25-26 mpg. If my wife and I take advantage of this, there is very little reason we could not consistantly hypermile the car when the 30+ mpg on the highway is averaged in - and having the guage right there under our noses will help to drive that home every time we drive.
