IPC settings

What IPC settings can be adjusted?

There are tons of individual settings and parameters that can be adjusted in the IPC (Instrument Panel Cluster) module. The following is an abbreviated list of the most popular/commonly adjusted parameters to give a preview.

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.

Also note that the UDD (4" color DIC screen), UHS (8" color DIC screen), and UDC (black&white DIC screen) instrument clusters all have different capabilities and options; some features might be able to be adjusted on one model, but not able to be adjusted on another model.

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.
