Ah okay. This simplifies the setup a lot. I had done some testing and validation of ECUs 9 years ago. So my questions were based on the understanding I had developed back then. Thank you for clarifying it. Again, awesome work :)

If my car relied heavily on CAN (like the next generation Commodore) I probably would have sold it.

I love CAN bus (for my own designs), but I don't see the effort of attempting to reverse engineer GM's format as worth it, especially since I had no prior experience with CAN.

Thank you :) I've got another D automotive project which I hope to write about soon.
