Porsche and others has the same style of ECM. It's more just a style of management than a system that is more secure. You have one central brain and then a few dozen modules that spider web off of the main ECU. It's pretty organized once you get into it and start to understand it. It will probably help tuners in a lot of ways but there will be an added challenge of accounting for the other modules, but it can be done. It already has been done.
