I found another ID for CAN which are responsible for:
0x754 - Telemetry (GM5T) - CAN-HS
0x7E4 - Battery H1F8 - CAN-HS
I have already saved the full CAN ID table for FFE.
Anyone willing to help in coding Arduino?
I have a CHAdeMO connector, I have arduino + CAN add-ons.
Sefs, battery values 0x7E4 do not fly in CAN? Need to ask BECM?
