edge evo questions

You can put any tire size in there. The manual that comes with it converts the tire sizes to a number that you put in. I believe the number is revolutions per mile. Changing that corrects the speedo, and it will give you a better reading on the miles per gallon. Nothing else changes. You may have to play with the tire size a bit and check the speed with a gps if you have one. Also, the edge speedo reading will be a couple mile an hour lower than the truck speedo. The trucks read slower than you are going. The edge reads the actual speed off the PCM.
The GPS confirmation is the best way to confirm the correct tire size and GR.
Start with 3% squish and adjust from there using a GPS or known distance:
