Small Update:
Parameters auF1718, auF2552, auF2531, auF12105 control the data which is sent on CAN ID 0x623 bytes 0-3 respectively(0 being the first byte).
I am still mapping the rest, and as for how this can be used in practice to match ABS Config to PCM Strategy, the end goal would be to have the ABS configured as per the physical setup on the vehicle, so Xr6 NA should really be set to Xr6 NA Configuration in the ABS module, but to have that work with an Xr6 Turbo Strategy/PCM the above is likely what the ABS module reads before deciding if it is good to operate or if it will go into fault mode.
I suspect that on the same makes the ABS module and pump hardware is all the same, this makes sense from the point of the manufacturer, however there is a lot of different hardware between BA/BF/FG/FGII/FG-X as well as 3 different diagnostic protocols. This means that in theory, as long as you can tell the ABS module the right data you should be able to match the correct ABS config for the vehicle setup to any PCM strategy.
More to come.
