I gave up using it because the data changes so often, and by such large amounts that it is almost useless to me.
I ended up just using it to estimate the averages of a trip versus the instant MPG.
I wonder if the Scan-Guage and MPGuino display the same behavior.....
Hi Cd,

You should be able to get much better results with the ScanGauge II.

I originally used one on the 1996 Chevy Cavalier when I started eco-driving back in 2007.

The ScanGauge was great...

1) Get to a steady speed
2) Hit reset on the total MPG display
3) Drive over several miles
4) As the miles accumulate, the display gets more steady, since it's constantly averaging the results
5) Write down your numbers and get ready for another trial

Look up the specifications for the ScanGauge, since it has a lot of options.

Now I use it for keeping track of throttle position (TPS), water temperature (radiator block), air intake temperature (hot air mod), and 12V battery voltage.

It's a nice unit, and even comes in handy if you want to read scan codes.

Jim.
