I know you guys are gonna think this is crazy, but I just started a new job and wanted to see how many miles it is from my house to my office building and when using my wife's 2005 Escape the mileage came out to 7.1 miles but when I checked using the Cobra it came out to 8.5 miles. I would hate to think that my odometer is fast or if that is even possible. The car is 20 years old so I guess it's plausible. Is there a calibration that could be done?
