Yes, I believe there is something in the works that will require manufacturers to release this information to the public. I can't think of it off the top of my head, but I was just talking with someone about it the other day.
There is some information that is buried around the internet, but to complete full integration you would need a working relationship to retrieve this information.
I believe there may need to be some hardware modifications to work with Chrysler enhanced functionality, but I have done little research in the area of Chrysler specifically.
You can retrieve enhanced sensor readings if you know the codes.
