looking for an open copy of the 7603 XDF

Does anyone here have an open copy of the 12587603 XDF file. The copy that I have is encrypted, but I would like to use it to build an XDF for the 12606807 bin files like the one I have on my 06 Sierra. There are a growing number of people out there looking for a way to do a few simple mods to these bins and no one seems to be working on an answer. I'm not smart enough to work straight off the binary code but I feel that given some time I could modify someone elses brains for us to use.

Thanks in advance to anyone that can help or even point me to an xdf that will work with these OS.

Assuming you found it by now but it is the first sticky under OBDII Tuning. Here is the link:
