I've been using a ScangaugeII for a few months now, and have been very happy with it. Prior to the SG2, a lightfoot, and a lot of restraint, would consistently yield a tank average of ~34 mpg. Now with the help of the SG2, I have recently achieved ~37 mpg on my latest 3 tanks of fuel! Today marks the first time that I will have ever gone over 400 miles per tank! I will fuel up in the morning to learn the results. I am hoping for my first 40+ mpg tank!

A few months ago at the time of my SG2 purchase, the Kiwi was announced, but not shipping at the time. Well, now I see an interesting newcomer called the SuperMID. I first learned of this device at Ecomodder.com , anyway, here are some links describing such devices:

Oh, another perk for owning an SG2 is for the ODB II code reading function.
Prior to getting the SG2, I took my Fit to the Honda service department to checkout a thrown CEL. In doing so, it cost me $100, and over an hour of my time, for them to tell me that I had a VTEC solenoid issue.
Since owning the SG2, it has already solved one thrown CEL for me. When the code popped up, it informed me that I had a fuel pressure issue. Luckily, the problem turned out to only be a loose gas cap. The beauty of this story is that the SG2 saved me $100, only took minutes to determine the problem, and allowed me to reset the CEL with the push of a button.
In code reading fees, and fuel savings alone, I feel that my ScangaugeII has already paid for itself!

After reading dozens of rave reviews for the Scan Gauge II on other forums, I also bought one a few weeks after macbuddy. I don't drive as much as he does, so I have not received as much information from mine yet. But to repeat my recent comment to him, I think that it is a little funny that the gauge tells you, when coasting down a mountain road, that your MPG is 99,999.

If I could find destinations that were all downhill from each other, a tank of gas would last me ten years. But I would never be able to get back home that way.

Not so funny- when driving uphill, I get as low as 4 MPG.

Does the SGII show ignition timing? Never mind looked at the specs and yes it does. How does it show engine load?

I can't answer, John. There are so many damned gauge categories I haven't found that one yet. Mike may be able to answer you sometime since he drives a lot more than I do.

No problemo just saw that in the specs and wondered how it shows it like high ,med, and low or by some numerical valve.

Hey John, the "load" display shows up numerically. For example , the SG2 might show something like "43LOD" on the display. This would designate a 43% load reading. Checkout page 6 of this PDF:

This morning, I was anxious to check my latest mpg. By the time I got to the gas station, my odometer read, "400.4 miles." I finally did it, that is the most miles I had ever gotten on one tank of gas! With the fuel topped off after several clicks, I ended up putting 10.42 gallons of 87 Octane into my tank.
So, after a little math...
400.4 mi. / 10.42 gal. = 38.43 mpg
Well, I didn't get my 40+mpg, but I did set a new personal record of traveling over 400 miles per tank!

-macbuddy-

PS- 38.43 mpg X 10.8 gal/tank = 415 miles per tank
(I guess I could have gone an extra 15 more miles!)

So, your average would be around 49,999 mpg? :)

"Meter readings are subject to interpretation" (and good sense). I would say----- "No".
