ECUMaster EMU CAN Broadcast Protocol

ecumaster

CAN broadcast protocol for ECUMaster EMU BLACK and EMU PRO ECUs. This protocol is the default ADU CAN stream used for communication with ECUMaster ADU displays, data loggers, and other CAN-enabled devices. The protocol uses 11-bit identifiers with configurable base address. Default base address is 0x600 with messages spanning 0x600-0x607. Each message contains 8 bytes of data in little-endian format. Temperature values are transmitted in degrees Celsius. Pressure values are in kPa (sensor configuration determines gauge vs absolute). Lambda values are transmitted as raw lambda (0.65-1.30 typical range).
