how many miles difference? is it worth it to go through the steps to get it updated?
id imagine the LEGAL way is through the dealer. there are videos online that show you how to do this but it requires special equipment and maybe even a code to access that part of the system.
why not give a local infiniti dealer a call and see what they say? the cost may be high, and you need to show a valid reason. make sure you noted the original mileage prior to replacement.
