I bought a Scangauge about two weeks after I got my Yaris. Pre Scangauge I went from Reno to San Leandro (230 miles) and averaged about 41.5 mpg. With Scangauge the same trip was 48 mpg. Traffic was a little worse the first time I admit.

Before the Yaris I had a '94 Metro. I just wish I would have tried driving the Metro using my new FE skills taught by the Scangauge. I was getting 52 mpg in it before, maybe 60-70 mpg would have been possible.

I am a believer in the Scangauge. So far 5 people I know have bought Scangauges after seeing mine work.

I have previously come to the conclusion that because my 94 Metro is OBD-1 I can't use a scanguage, right? What can I use? Where do I buy it? How much does it cost?

Right, GeoMetry. Because you're OBD1, you'd have to use the SuperMID. I think they're around $160 US, but I'm not certain - don't hold me to that. Ask Matt or Yoshi.

Better ask Yoshi :)

What can I use? "SuperMID"

How much does it cost? "$160"

Where do I buy it? ???????

GS member Yoshi. He makes them. (PM him - that's his usename)
