Mystery module

Hey everyone, I picked up a used jb4 w/bt yesterday and this module was in the box. I can’t seem to find anything on the BMS site that resembles it.

Anyone know what this is?

Might have to cut open the heat shrink to see what's inside

Nah, sorry I figured this out a few minutes after I posted.
It’s a bms dp fix, if you have catless downpipes it mimics stock values to pass inspections
