Need help on M84 CAN bus data protocol

[zhaozdi]

We are building a custom dash for M84, the dash gets data from M84 via CAN bus. I have got a data protocol description for M800 from this thread: viewtopic.php?f=11&t=1498#p6872.
In this document, a M800 data package has 176 bytes (byte0~byte175). But our M84 outputs packages that only have a length of 80 bytes, much shorter than M800 packages. We are confused about it.....

I wonder if there is a data protocol description for M84, maybe it's the best way to solve our problem.

Thanks!
