Sorry if this has been covered. I expected to see a lot of posts about it and see none. I have a Superchips Flashcal that I bought in 2015 for my 2013 JKU. It worked great the two times I needed it back then. I used it again last week when I changed 33s for 35s and am getting odd results. Tire size wont change. Other settings I didn't touch are changing. Called support they said I need to buy a new one. This one isn't supported. That seems odd. Any thoughts?
