I have my Tactrix OP2 configured using the logcfg.txt to get all the standard stuff; extended parameters, analog input(WMI Duty) and serial input(WB AFR) - no problems there. What I would like to do is be able to log messages that are broadcast onto the CAN bus using the SD card.
For example the
AEM X-Series Wideband 30-0300 has an optional OBD pass through to allow it to put AFR directly on the OEM CAN bus.
500kBuad, 29bit, 100hz, Big Endian, DLC 8
CAN ID 0x00000180
Byte 0-1
Scaling .0001 Lambda/bit
I think this would be a good way to add more logging channels (planing on EGT) to the OP2 as many standalone ecu manufactures have CAN enabled sensors. One concern I could see is overloading the OEM bus, I have not measured the bus load yet as I am waiting for an OBD slitter to measure with all the parameter requests running on the OP2. Does anyone know the syntax or if it is even possible to log specific CAN messages?
