Getting nice results with Scangauge II
I got my Scangauge II in yesterday, and let me say if you don't have one.. I highly recommend it. I have already improved 1mpg (city driving) in less than 2 hours of having it installed. I didn't think the thing would pay for itself like the company says but I believe now. It costs double than the Ultragauge but I didn't like the negatives on this forum about it draining battery, so I didn't take the chance.
Anyway, what I've learned is when you have a steady foot on a relatively smooth city highway without a lot of stopping, the car @ 40mph gets 48mpg average. I am going to test the highway portion today to see what the best speed above 50mph should be.
In the city:
Acceleration from a stop in first gear (auto) nets around 7mpg average.
Acceleration in 2nd gear usually averages 13-15mpg.
Acceleartion in 3rd will put it up to 25mpg.
And fourth gear will get you 30+ and long range without stops will easily get you 45+ mpg.
The thing really teaches you how to get the best mpg out of your car (since you are eyeballing it most of the time). I am hoping to up my city average to 35+ from 29.
Its super easy to program the x-gauge feature and I had no problems cycling through to get to where I want. I have not tried the tank trip feature because I am far away from another fillup.
The only downside is with the Focus OBDII cover, it doesn't snap on to the rest of the dash, its kind of attached to the dash and doesn't come off. I can live with it just hanging down as its not really in the way of much. If anyone has a better idea then I'm all for it.
Routing the Scangauge is easy if you put it right below your gas/temp gauge, you can simply stuff the remaining wire below the steering wheel. Anyway, I'll post more feedback on the highway mileage later on.
