The maxisys scanner I have can do it all, I can swap in a different engine and program the ECU to match the dash and I can program in the VIN from the car, I can also swap in a dash and correct the miles to the truck or car. No matter what they do to try to keep people from "fixing" miles someone will hack it and commit fraud. I always always tell people who are looking at cars to ignore the miles and buy the car based on the condition of the car. Car fax is better than checking miles because you can see if the car is from a state that builds cars (they salt the roads to get rid of the cars and sell more new ones). I was trying to find a handicap van for my ant and I kept trying to get one in LA Phoenix Vegas and kept finding great deals but they ha all spent the first 5 years or so of their life in places like buffalo, millwakie, chicago... those places down south were laundering rusty cars from up north. We finally found here one in Phoenix from Phoenix and it had more miles but was much nicer underneath than all the newer lower miles units we kept finding.
