Update:
BMS sent me a new main chip
It connects through OBD now, and I only have access to boost and map gauges on the JB4 software.
On further inspection the BT module was also found to be baked.
BMS has sent me a new one, and I'm waiting on its arrival... fingers crossed!!
CUDOS to the support folks at BMS!!
They have been great working patiently with me to resolve these frustrating issues!
