OBD2 and interface
I have a 2009 Jeep Grand Cherokee I remember reading somewhere but can't seem to remember what I was told to look into kow that I have funds available to purchase. I was told I can get a obd2 wifi or Bluetooth and that I can buy a program at which I can "flash" my jeep. I added the mortar trailer harness and hitch. Does anyone know how to flash the jeep using an app thats via phone to obd2.
