The truth is that unless someone "discovers" the key, either through blind luck or a leak from the inside, decrypting the data once you have hacked into he box will be a long tome coming.
I'm not saying it can't be done, just that it's probably not going to happen overnight or without some help from the inside.
The latest i've read was the new ECM's include code that tracks every change in areas that can't be overridden. Even if they allow access the dealer systems will be able to identify any change and will immediately flag the VIN making warranty claims difficult if not impossible for any engine and trans related issues. If tuning is that important to you and you are willing to flush your warranty down the toilet then have at it. And before any of you Magnusson Moss devotees chime in, all the manufacturer needs to do is prove the code in the ECM has changed and unless you are willing to spend the cost of the vehicle again in legal fees you are SOL.
