I would like to expand on this a little. The new boot loader trap is in the new ECMs and not in the current 2007.5 and 2008 units. It is unclear if the dealers with their tools can load or want to load a new boot loader. If done wrong, can render an existing ECM dead.

Basically you are changing the operating system of the main computer and its specific to your VIN. After that change, a lot of other code has to be changed also to support it with additional information to inserted into the ECM. Why do I say this ......

If what the new boot loader code does what was done with BMW and MINI, it most likely is based on a form of x.509 code. Which mean in simple English is that for each code module/function, a algorithm is used to generate a very complex hash code that is very long (same stuff used when you purchase stuff online to protect you information and connection). The computer uses what the manufacturer supplies and compares it to what it generates on the fly (seed information stored in that code) an if they do not match, generate a cripple signal, lockout the computer. There is a lot required to do this and is rather complex and this why I feel that the dealers can not install this on existing units. Now the updates that Cummins releases will for sure have the needed subroutines in it to make the trap work, but on units without the boot loader, it will do nothing. The ECM is not damaged, just has to have things cleared and code reloaded most likely. Which I think can only be done Cummins so they can do forensic work.

I reversed engineered the code on my BMW/MINI computers

If something happens to your ECM, and its replaced, then you will for sure have the new code.

Can this be altered and different code information installed, yes. It rather complex and your automotive hackers has not gotten that far yet I think. In the computer security world, the tools generally available and made somewhat easy. Now if the computer security hackers and automotive hackers combine efforts, piece of cake ..... NOT saying anything more

I am not saying someone is right or wrong, the information posted about this is extremely valuable. Just presenting some additional information based on my experience working on such things and software development.

Hope that helps.
