I don't think you can currently add a PID with more than one byte. Maybe CAN sniffing could work but I'm just starting to look at this for my application as well. Where did you find the information for the PID you're trying to add? I'm trying to get similar information from a Ford vehicle.

Has anyone figured this out yet? I'm trying to get battery module voltages from a Bolt EV.
