Out of the box both the Ultragauge & Scangauge are about 21-22% optimistic on my '05 manual Corolla. The actual calibration number I use on the Ultraguage is 2.186. Usually within +/- 1 MPG.
Averaged mid to high 30's during the winter the first 8 years on this car. Thanks to this forum & the gauges I haven't had a tank below 40 MPG since February 2014. I don't pulse & glide much & never EOC, so could do better, but am a very happy camper none the less.
