You tell me that you can crack software that is encrypted.
Well, I gave you a few examples of unencrypted, relatively easy software that is widely available (and operate in relatively easy ways to decipher).
Windows 3.11
Dos 1.0!
Show me you can reconstruct from executable to boolean to source code.
If you are in the software business -- feel free to ask any programmer what I asked.
See if they can do it.
If you can, I will be very confident of the ability of any competent group of software analyst to figure out what the code is actually doing by reading the source code.
If you can't see the source code, the flow charts... there is no telling.
I have never known a major car manufacturer to release the source code for their ECM.

Please post some facts to this software...no pretty pictures needed as i work for a software company and feel i could follow along!
My understanding is the software suite for the 250 and 350 are materially different beginning with the 2010 model.
The software is stored encrypted, and decryption is protected by the DMCA.
However, it is possible to black box some of its functionalities with a bit of work.
After all, it was possible to black box x86 and make a work-a-like without knowledge of the microcode or a license.
There is, of course, no "proof" unless you know of a way for me to gain access to the source code.
However, blackboxing did reveal some tweaks.
At the moment, I am of the view that the modules for ESC are quite different for sure. It has to be specifically tuned for the load range, and the eventualities of towing really changes the programming.
Because the auto makers funded some academic studies on ESC, some of that stuff got into the public domain.
Braking, ABS... probable.
Thermal management, almost certain.
We know for a fact that post 2008 Ford and GM (actually 2010 for sure), engines can be run dry of coolant and active thermal management can keep it running.
Since you are in the software business, I am looking for a good review article on the state or the art in back engineering from executables to boolean.
Can you help?
Note: the full software suite in many cars now are in the 100 million lines of source code range.
You said that a trucks computer software can up it's towing ability by 25%. (This has nothing to do with CAD, or trailer frames, or airplanes; it has to do with a trucks computer and the software in it.)
With the same frame, same tires and wheels, same HP, same rear end gears, Et/Al........exactly how can software increase the tow rating by 25%?
~ Too many freaks & not enough circuses ~
"Life is not tried ~ it is merely survived ~ if you're standing
outside the fire"
I am not into computer code and software and all that.
From a layman's point of view on that topic, the only way I can see software installed in a truck's on-board computer being able to affect it's ability to haul weight is by changing the power output of the engine, the shifting characteristics of the transmission, and changing the way the roll stability control system operates. The physical, mechanical properties and strength limits of the hard parts of the truck remain the same.
So we're talking about engine power output, transmission shifting, and manipulation of the ABS braking system to affect towing power and, to some degree, handling and braking, in an emergency maneuver. That does not increase the strength of the tires, wheels, axles, suspension, or the rest of the chassis of the truck, which actually physically carries the weight.

I am starting to really not believe a thing you post...just my opinion as others may believe you, but i would love a link to where ford states this.
In my view, if you want that level of proof, you got as much luck getting the source code of the latest Airbus!
This data is their secret sauce, and will not be released to the public.
I can't even get Ford to admit in public they encrypt the modules!
Nor can I get Ford to admit they are caching data about what is being done to their vehicles (tuners, etc.) all over the place!
If you want proof from Ford, get a job with them in that unit.
Something that might be feasible to ask them to do in 10 years is to release portions of the source code for an obsolete engine (like the 6.0) but not the whole thing.
