I just spent some time today to unplug the ASC and can confirm it does not effect the exhaust modes.
After messing around with all the settings I am thinking the Engine mode AND Engine sound effect the exhaust valve but not 100% certain. Id need go pro mounted looking into the exhaust valve to be sure, but when I unplugged the ASC and swapped the engine into +R mode on the highway I definitely heard it change tone. I think I'm left with more questions than answers but all I know is I will be leaving it unplugged. The owners manual doesn't have any details on what exact changes are made to the car in each setting either which is a little disappointing.
I may be more leaning to Engine sound effects pumped in audio and Engine Mode affects throttle mapping and exhaust. They could be intertwined too
I did sit in the driveway and have my wife rev the car as I changed a few modes and did confirm the valve was working and opening as it should though with it unplugged.
