my own disassembly and XDF for the common version of 6D. there are a couple of BINs that use a slightly tweaked calibration section, at the very least, APWC, ARCS and ATWX are the oddballs.

this disassembly also has very little algorithm defined since i knew enough about it via A1 to decode ~99% of the calibration. the parts i couldn't quite define were mostly for DTC qualifications and some EGR stuff.
