MaxxECU default CAN output protocol, version 1.3 (2020-09-29)
•13 % extra CAN bus load when activated.
•Includes data from version 1.2.
•0x536 byte 2+3 is now used, was not used (SPARE) in version 1.2
MaxxECU default CAN output protocol, version 1.2 (2014-12-05)
•7% extra CAN bus load when activated.
Note: DBC files are available on our website download section.
Specification:
•Can baud rate: 500kbit, 11-bit ID.
•Little endian (least significant byte first).
•Most messages contains 4 16-bit values, 8 bytes per message.
•Some messages contains a combination of 8 and 16-bit values, 8 bytes per message.
•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.
