Many thanks!
I found a different location using google that was on my way school. 3 miles long with an intersection at every mile. The calibration actually increased my MPG, lol. Also is it normal that my odometer got the distance correct(3.0), but ultra guage was 2.85ish. I thought both these devices got information from the same place
As far as the reading problems I am going to try putting it on forced MPG using the MAF sensor tomorrow. This is the sensor my car has and ultra guage says its using the MAF sensor, but I figure it can't hurt. Then I will just start the fuel/MGP calibrations and see how it goes. In February all 3 fill ups I did averaged 23.5MPG using the miles traveled/gallons pumped method. ATM ultra gauge is displaying an average 31MPG. I know its suppose to help increase MPG by changing my driving habits, but I just don't really believe what it is saying. I haven't changed my habits THAT much yet, I set the alarm off twice this week due to "excessive RPMs"
