BCM settings

What BCM settings can be adjusted?

There are hundreds of individual settings and parameters that can be adjusted in the Body Control Module (BCM). The following is a VERY abbreviated list of the most popular/commonly adjusted parameters to give a preview. In reality there are TONS more features that can be adjusted!

Please note that there might be minor differences in tune setting descriptions/limitations/capabilities depending on year/model of vehicles due to operating system software changes that GM has made over the years.

You do NOT have to have any licenses purchased to view all of the available tune settings in your web profile; you are free to explore, however the AutoSync will only download/install tunes into your vehicle after you have purchased a license.
