In order to tune ECUs of relatively new cars you now need to remove the ECU and flash it on the bench which bypasses the anti-tuning processor.
Yes, manufactures are making it more difficult to remap an ECU but they are still required to have their EPROM chip both Erasable and Programmable just for them to update softwares so they will always be a way to tune an ECU but it is getting harder to do!

I wouldn't say it's impossible..You mustn't have seen the countless threads on portable flash at HOME units VIA OBD for a significant amount of $ compared to the jbd by ess, Cobb, giac to name a few. You gotta pay to play.
