    Can VCM Editor set NPP Exhaust parameters for a 2012 - ZL1?

    There are 5 channes reporting data during a log that appear to be related to the NPP exhaust on my 2012 ZL1. Can these parameters be edited with the VCM Editor? If so, is it possible with the MPVI2 or MPVI3? While logging, I can see the channels and data is being reported. However those parameters do not appear in the VSM Editor, even in Advanced mode.

    The following are the 5 channels and their reported values during the scan.

    Exhaust Valve status Disabled
    Exhaust Valve Enabled Yes
    Exhaust Valve start Rumble Active Yes
    Exhaust Valve open Threshold 0 %
    Exhaust Valve close Threshold 0 %

    Thank you

    You need to read/license the chassis control module (CCM) to access the exhaust valve tables.
