Piped in sound via the stereo

Didn't believe it the first time read that and thought just for 'that'
model and the targeted 'car' buyer...

But am reading it on this forum of 'truck' & 'tow vehicle' owners

Do they sound so 'off' that the OEM(s) are spending the money to ID
what it the desired sound. Record it through out the rev range and
throttle settings and loading

To then design a system that senses the throttle setting, RPM, MPH, etc
to process that sound through the stereo...even when the stereo is
turned off

If you pull the OEM stereo to replace with an after market stereo...does
this fake exhaust sound still work through the new stereo?

Amazing...

    Pull the OEM radio? You've not spent much time in a late model vehicle have you? If I pulled the radio out of our Edge, we'd lose climate, radio, navigation, and phone bluetooth, not to mention controls for the mood lighting, headlamp delay, etc.

    I seriously doubt JVC or Pioneer has a model on the market than can talk to all those systems.

    Do they have different sounds you can select. I really like the sound of my Cummins.

    It is correct. A tachometer sense signal wire feeds a dedicated audio circuit in the OEM radio. This is the next step from the speed sense line that is used to adjust stereo volume. If you replace your OEM radio with aftermarket, you will lose the artificial sound.

    A while back, they started using speakers to cancel out exhaust and road noise in the cabin by placing a microphone into a feedback loop that would send the same sound 180 degrees out of phase. Funny how they are now "enhancing" the sound through speakers.

    Don...I didn't believe at first and thought a joke, but is now well documented
    and more models are getting this 'feature'

    It adds value if it makes the sale !!!...right?

    Am told that even when the stereo is 'off'...it is on for this 'feature'

    I think they are aiming for perceived value. When I test drive a new or used car the first thing I do is turn off the stereo while testing.

    I saw a TFL Truck video of them towing with the Ecoboost F150 and mentioned that the engine sound was piped in through the stereo.

    I'll see if I can find it.

    Found it, all though to my ears and crummy computer speakers I can't tell the difference.

    Manufacturers have made some cars so tight and so soundproof you can't hear the engine running inside, and yes, there are some people who just can't stand it, and are willing to pay extra for fake engine noise.

    On cars that have this feature you are not likely to be installing a custom stereo system.
