N54: JB4 canbus commands

Does anyone have any information on what commands the jb4 send over can and the format is expects to receive parameters in?

All I can find is Terry stating it uses the x6f1 diagnostic port... Doesn't tell me much.

I just need to know what response the jb4 expects the dme to provide
Eg. 612 xx xx xx xx xx xx xx xx xx

And what position/byte/word in the response corresponds to which logged parameter. I am using the jb4 with an ms43 and can retransmit any parameter from this dme over can with any telegram format required. Just need to know where to point it so the jb4 can read it.
