My Yaris compatible with Ecometer?

It finally leveled off at 31 mpg. That's 3 mpg less than my first one showed. They sent me another free one and I'm going to plug it in to see how its figures vary from the other ones. I now see why some people get high readings while others get lower ones. It's made in the USA by "skilled craftsmen". Skilled for American standards or what?

Did you calibrate it over time by adjusting the EFF values? One of the members here stated they didn't have to adjust the value when using stock tires, stock wheels, stock tire pressure, and the stock air filter. I have mine set to 94 but I also run my tire pressure at 44 PSI and I use a K&N air filter.
