The ECUs have always been coded, the code crackers are in business to stay up with the game and that's part of the reason some of the re-maps cost as much as they do. Time = Money.
VW don't want people hacking into their ECUs, re-writing the expensively assembled software and then going back to VW trying to claim for running problems under warranty. VW group sell an awful lot of cars around the world and they probably also don't want other manufacturers nicking their ideas either.
