So...I cant say from personal experience that any of this is true, BUT I have read that these wireless OBD plugs can actually cause severe computer issues if there's an interruption or issue. I don't now how true this is, but I do know that if something interrupts something like the Procal's transmission then you can brick the computer. I know that's a programming function that's interrupted vs a read but maybe someone else can attest to these issues and the level of concern/truth there may be to them.
