370Z CAN Bus Proprietary PID's

SouthArk370Z

I have an ELM-based CAN-to-USB adapter. Would it be possible to get a copy of your program?

I don't believe my code will help you in your case. My code is C++ firmware code that gets loaded to an Arduino and communicates directly to a MCP2515 CAN controller chip via the SPI protocol. That data is then translated to UART to communicate to the PC to see the results.


I just used Hercules to view the COM port.

RS232 terminal, serial port terminal, udp terminal, tcp/ip client server - Hercules

The hardware you have should do this already. If you use Hercules, you can log data just as I have.

The advantage of having such a low level interface is that once I start understanding what the data is, I can program my Arduino to start doing stuff with it!

I am writing a program now that will allow me to view all the data on the CAN simultaneously by PID. That way, I can start messing with stuff in the car and see what data changes and how.

Ah. OK.

The hardware/software I have found work great for monitoring params if you know the PID, but I haven't found a free program that will do bus sniffing.


Please keep us posted on your progress.

I wrote a test tool for the incoming CAN data. The program reads in the CAN stream from the arduino and displays unique ID's and their data length. When the ID repeats, the line containing that ID gets updated. This allows me to view a static arrangement of all the PID's and watch how their data changes in real time.

Output format:
XXX: XX XX XX XX XX XX XX XX
PID: D0 D1 D2 D3 D4 D5 D6 D7
