Is there a way to test the accuracy and or adjust the Speedo? I know mines reading high or else Clay and Betty really were driving 90mph on the freeway last week. (IMG:style_emoticons/default/w00t.gif) Bill

Time yourself between two mile markers. Stay at the same speed between the markers. 3600 divided by however many seconds it took you to drive one mile will equal your speed.
Took me 63 seconds to drive one mile....3600/63=57MPH Took me 51 seconds to drive one mile....3600/51=70.6MPH |
