You will more than likely have issues with the Canbus data rate/bandwidth.

BMS products labeled for use only in competition racing vehicles may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event, in accordance with all federal and state laws, and may never be operated on public roads/highways.

Anything the laptop tells you won't be accurate anyway. The JB4 is changing parameters, but the ECU doesn't know that. The laptop will show what the ECU sees, which isn't reality.
