I got a edge programmer for my truck and every time I enter the tire size for my 35s it changes it from 2792mm to 2794mm. Does anyone else have this problem?

I too believe it's silly our Evo's/Gryphons won't save the tire size data. Although, you should be secure in knowing that the truck IS programmed to what you set it to. It won't change in the ECM unless you reprogram with different values.

Just go with it, not sure why its changing it, 2792mm is what Edge states in the manual. Several mm could account for new tires or worn tires though so you are good.

Mine does the same exact thing. Mph is pretty close if not off by a mile or two. I wouldn't sweat it to much.

I need to correct my speedometer with the stock tires. The speedo always shows that I'm going 2MPH faster than my actual speed as verified by GPS and radar. If I change the tire diameter to correct this, will the speed display on the Edge then become incorrect (it's actually correct now)?

as long as you input the correct mm for your tire size both the edge and speedo will read correct
