I only retrofit a CIC on my 06 e91 and read the 1b with a chinese dcan.

Edit to add that think the procedure used by each one is different, but both are valid. The first (i used too) is with dcan cable and with the SW ID reader tool you can read the 1b file, and the other valid way is via ethernet, with the dlink adapter, via ftp access to where the file is located and made a copy of the file.

I just made it once with my cic but think both ways are valid, or at least for me it worked.

If you use to activate the cic with the can filter, you would use the first i think, but if you got the the dlink adapter for script activate ... once you are connected to the cic, you spend 1 second to made the backup of the 1b file.
