I'm using Alpha OBD with the OBDLink MX+ MX201 to try and change my tire size. I connect, go to BCM, body computer MY2019, choose tire size, hit "start", "next", but nothing happens after that? I've tried turning the truck on and off, typing in the tire circumference in mm, but nothing seems to work. It looks like it's connected (says it is) because it shows the currently programmed tire size. Am I missing a step?
Note: I think I have the security bypass wired into the OBD. I wired one in to allow for tune flashes. Does this work for the AlphaOBD flash also, or is it a different bypass?
