Well, I bought the Ultra-Gauge a few weeks ago and it came in the mail. Nice small little unit that is like the ScanGauge but has a WAY better screen and shows 6 gauges per page, 3 pages.
The cool part is that besides showing and clearing codes, avg mpg, instant mpg and all the other stuff like O2 trims, IAT etc, it also shows gallons left in your tank.
Spent a few hours yesterday just driving around and calibrating the speed to GPS and playing with settings. The last few times I manually checked my mixed mpg it was 13.5-14 but I just realized that my speedo is off by 8% under-reporting !!!
Doing a test of avg mpg for the next few days vs actual gas used / mileage to see how accurate it is. I have heard once calibrated it is extremely accurate.
For $70 I just couldnt help myself... http://www.ultra-gauge.com/ultragauge/index.htm
