BMW F8X M3/M4 CAN Mapping

Post by ferrarif1 »

Has anyone endeavored to map the bus on an F8X? I assume this will be very similar to an F3X and F2X but before starting from scratch it would be preferable to leverage the work of others and contribute new mapping from there.

Hi,

You might be the first one. Do you have access to any documentation on the CAN protocol for either of the platform?

One of the first things you can do is log the raw data from your RCP and see what your ECU is outputting:

The general CAN mapping guide is here:
