there was and still is no mention of any sofware differences.
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%?

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.
