Specification:
•Any baud rate, 11-bit ID.
•Little endian (least significant byte first).
•All MaxxECUs has a built in termination resistor on CAN 1. External termination (120 ohm) is recommended for bus lengths over 1m.
•MaxxECU PRO with a secondary bus (CAN 2) does not have a built-in terminator resistor.
•Wiring loom: Twisted pink / gray. Pink = CAN L, grey = CAN H.
V1 standard base ID: 0x600
V2 standard base ID: 0x450
Some of the Powertrain controller have the possibility to adjust the base ID using the CAN ID Offset setting. Example if you enter CAN ID Offset = 2, the V1 protocol will listen to 0x602, 0x605, 0x606 and 0x607 instead of the standard 0x600, 0x603, 0x604 and 0x605.
