You do not need trace files.

The most important issue is to make sure you have a compatible JBBF installed. You can check on Realoem the units that are compatible with a 1M. They MUST be listed as an alternative. A 135i JBBF does not have the servotronic option.

Once you have that installed the correct JBBF, code in option 216 and you are good to go.
