Is there an easy way to disable exhaust sounds through the speakers?

[Dale_K]

I have a thread going about making my 2024 quieter and there has been a suggestion that turning off exhaust sounds through the speakers might help. First of all, can anybody confirm that an EcoBoost convertible actually plays engine sounds through the speakers while driving? And if that's true, can it be turned off with software? I'm not familiar with using Forscan.

To my untrained ear, there isn't much simulated noise unless you're flooring it.

I cold start with windows down in a small garage and have listened carefully as the engine settles out into normal idle, and when pulling out of my neighborhood etc. it seems to be real noise that reverberates off walls/buildings nearby, not simulated speaker noise. In S550 Ecoboosts the "fake V8 noise" was easy to discern, it was much lower in tone than the real engine and sounded like a video-game car engine.

I believe S650 Ecoboosts with base exhaust do not have a resonator as standard, but the active exhaust may have one (thus why active exhaust Quiet mode is quieter than the base exhaust).

Actually, it's the reverse. Base exhausts have resonators, active exhausts do not. I don't know the engineering reason, but I can confirm my bone stock active exhaust car has no resonator and looking at online Ford OEM parts diagrams says the same thing. I'm hoping that adding a resonator will reduce the deep bass tones that drive my ear crazy.

i would go looking in the spreadsheet in the ACM page for something. also check out the forums of places for the F-150, Explorer, Focus ST/RS, and so on

I've owned an active exhaust EcoBoost for years and to my experience and knowledge I have never heard fake V8 noise on any setting at any RPM.

I've got a Dark Horse Premium (with AE) and don't recall ever hearing exhaust notes through speakers.

I also had a resonator delete with an H piipe so there IS a resonator on a Premium Active Exhaust car.

I can verify that the EB 'Vert does in fact play engine sound over the speakers. If you search ESE in the FORSCAN spreadsheet it will show you the addresses that need to be changed.

I have the car above (with active exhaust) and tried it. To be honest, I didn't like it, it was too quiet LOL. Also, when it was turned off, Track mode didn't sound much different than the other modes. Ended up enabling ESE and ANC and actually prefer it, IMO.

ETA: I realized that this is the same poster from the previous thread. I actually responded with the same recommendation above in that thread. It will require FORSCAN to make the change though.

Maybe a Forscan expert could look up to see if there is a setting to disable the feature. If there's a setting to turn it off, I guess it's built into the car. The guys responding to my thead about making the Ecoboost exhaust quieter seemed positive the "fake" sound was in there.

Its an EcoBoost thing.

Good advice!

It's crazy that you ask this again while in your other thread they already gave you the exact adress in Forscan.

I belive @GrabThatBlue already posted the correct address in the previous thread but maybe there is some misunderstanding, so I'll try and help.

Your EcoBoost does for sure play Engine noise over the speakers. You can turn it off though by downloading and purchasing a liscense for the FORSCAN SW and changing the code to disable it.

In the first thread on the FORSCAN forum there is a spreadsheet, look for the ACM tab, thats the module you need to change. The address is as follows:

727-01-01 xxxx xxxx *x--

There will be three blocks of numbers, you will need to change the first number in the third block.

Your car should have the following in the 3rd block:

xxxx xxxx 3EE3

Change that 3 to a 2.

That disables the Software Sound Enhancement or ESE/EV.

You can verify you car has this enabled by looking up your car's As Built data on the Motorcraft website and looking at that address. I hope this explains it a bit better.

Thanks for explaining that. I've been trying to read the Forscan thread and honestly my eyes start to glaze over. It's hard to keep up for the lay person with zero knowledge. I just want to activate the gear indicator.
