Does anyone know why this is not available? I know that I can just stay 5mph under the speed limit, but I also know that it affects my odometer, shift points, and efficiency of the power band so I would like to find a way to make it right.

We don't have an issue with our Axis...however, our Jeep speedometer is off due to tire size....we use the app on our phone called SPEED BOX .. via gps it tracks you and, like Garmin and Waze...gives you a speedometer looking readout on the phone ! Works for us...and it was free !

All I do to calibrate my RV speedometer is ask my mother in law. She's knows everything and is always willing to jump in and take over most anything. I just tie a rope around her neck and kick her out the side door on the expressway. Then I count the number of times she bounces before she begins to simply be dragged and multiply it by 4. Unless it's raining, then you multiply by 4 and subtract 6 from your answer.

LOL yeah my mother in law is always telling me I'm going too fast! She must have a built in GPS!
