Trying to unmarry quad from one truck LMM to another (same year) Have brought back to (Return to Stock) but still show last trucks VIN number when trying to tune new truck. Have heard you also have to 0 out all other settings such as gear ratio, tire size, etc. is this true and I will tell other person do so and will this screw up anything on original truck buy zeroing out the tuner. I heard the turner will then show XXXX for tire size etc when plugged into new truck and will then accept stock tune and new VIN. I think he left tire size in because he said he had changed that at one time. Could you please confirm this if true or is it something else we are missing.

I have searched everywhere for an answer and will post up if I ever find out.
