ScanGaugeII work on 2010?

[hotbrass]

So what gauges do you think are the most accurate?

I just got back from an overnight trip and did some trip gauge comparisons to real life data on gase milage.

The SG said I got 38.x mpg, the Prius said I got 42.1 and my calculation of miles and gallons from filling up yesterday before leaving and filling up upon return yielded 41.3 mpg.

Now I dont want to give anyone a heart attack, I know how green everyone here is. But I was driving between 75 and 85 mph most of the time. So in my opinion over 40 mpg going that fast is outstanding.

I think the ScanGaugeII is more accurate. The onboard displays for MPG and MPH use the same data that the ScanGauge uses but have built in errors. The differences are deliberately "built in" by Toyota. In the case of MPH about 3% to 4% to make sure the speedometer never reads slow, this is required by a U.N. regulation that car manufacturers follow because they sell cars all over the world:

Speedometer - Wikipedia, the free encyclopedia

In the case of MPG the error is about 5% and was required by Toyota marketing to try to convince customers that we are actually getting better mileage than we are. There are several threads dealing with this subject: 2010 Toyota Prius FCD Inaccuracy

I have checked my speed with a portable GPS and in the 60 to 70 MPH range the ScanGague is right on, the speedometer reads about 2 MPH fast. I checked my mileage (calculated vs displayed) very carefully on a 3500 mile trip and found the same 4% to 5% error others are finding. My Gen2 Prius had the same speedometer error as the Gen3 but it did not have the fuel consumption error.

Unless I'm mistaken the scangauge is as accurate as you calibrate it to be as far as fuel consumption.

Word I received from ScanGauge was that I was the first person to let them know the XGauges didn't work in the 2010 and so they are going to be programming some very soon. I should know as soon as they are ready. Going to do a BIG group-buy on the ScanGauge II soon if anyone's interested.

[hotbrass]

I bet you werent the first.

I contacted them after I got my scanguage and they told me that it would take a while for them to calculate the programming for the 2010. Probably not until early 2011.

I knew the moment I set eyes on the network map for the 2010 that
they weren't going to make much progress on that anytime soon.
Again, where are they [Ron and the rest of the scangauge crew]
getting their inf0z from??
