Negative, Paul. I confirmed it will not. It became a problem once I put my amp and my subwoofer in. And this was way after the FP tune. The sub woofer would just echo the exhaust note. You have to go in with either Forscan (as I did) or go into the liner and disable the mic.

Based on the change in the engine noise inside the cabin after installing the FP tune I would say that the tune does shut it off. Plus, when comparing my As-Built parameters that you change to turn it off with ForScan to the original As-Built parameters for my car they are different after the tune than before even though they are not the same as what I have seen published for turning it off.

All of the info I have seen published regarding issues with sub-woofers comes from the noise cancellation system not the sound symposer. Disconnecting the mics in the headliner is what most due to solve sub-woofers issues.

All I can say is the ANC is separate from the Sound Symposer that pumps fake engine noises through the speakers. I have disconnected the mics in the head liner and the overall noise in the cabin goes up which is not what I wanted but the fake engine sound stays.

This thread is specific to the Sound Symposer.

The sound of the engine inside the cabin very definitely changed when the FP tune was installed. I have seen (4) different strings for the 727-01-01 parameter that say they turn off the fake engine noises or the ANC or both. Since none of this info is official from Ford I don't take it as absolute fact.

Since I want the ANC to be functioning I never messed with that parameter since everything I have seen reported is the fake engine noise is turned off with the FP tune and my experience supports that.

Sounds like from your experience that parameter does in fact turn off the ANC.
