Is the 'Fake Engine Noise' for real?

[Rudy21 lariattremor]

I'm just curious.
I keep seeing folks mentioning it and even see folks using FORscan to remove it, but I have a hard time believing this is a thing.
I don't have FORscan to see if it's an option to remove it, so I guess I can't rightly argue it's not a thing. But it just seems really weird that Ford would waste engineering time to put this in.
Enlighten me.

if you fold the rear seat forward and lift the carpet off the rear wall right in the center you’ll find a sensor disconnecting turns off the fake engine noise. I did this problem solved. Trucks runs great no problems

That part has Nothing to do with the Fake Engine Noise - that sound enhancement is strictly software. The part you have disconnected is the Rear Antenna for the Pats system (remote entry)

I know the noise is gone now

Remote entry still works btw just went to check haha. Guys no need for forscan

What still works, your remote fob or the remote entry keypad?

My question is, what website directed you to disconnect the Rear PATS Antenna, it has NOTHING to do with the Fake Engine Sound - PERIOD.

The Remote will work as it comminates to the TCU, the rear antenna picks up perimeter approach from the rear with the FOB on you, it also ties into when you go to start the truck the antenna along with the other 3 antennas - validate the FOB frequency and allow the truck to start.
So specifically, it is dual function Passive Entry (rear approach) and Anti-Theft for the transmitter validation to allow a start.
The truck has 4 - Each Door Handle, Center and Rear - PATs Antennas.
The Center Antenna being the Primary (as this is the backup start location -placement)

PATS

The PATS function is controlled by the BCM, the PCM and the ABS module.

When the START/STOP button is pressed, a signal is sent to the BCM. When the BCM detects the START/STOP button is pressed, it begins the key initialization sequence by activating the PATS center antenna, the PATS rear antenna and both exterior doors handle keyless entry antennas. Each antenna transmits a low frequency signal with an approximate range of 1 m (3 ft). The passive key activates if it is within range of the antennas. The BCM is able to determine the passive key location (inside or outside the vehicle) based on the input from the antennas.

So, to test the operation, place the FOB in the back seat, and you may get a - No Key Detected Message when you attempt to start the truck.

For the record, my 22 Lariat had the sound disabled from the factory, so I have never heard it, I have also not dived into the audio system upgrades as of yet. I recall some having issues the with ANC (For the Voice Control-Mic) causing issues with an aftermarket SUB

Confirmation bias. It was never there to begin with. I have seen no definitive proof that Ranger even have this feature. I sure don't hear anything in my truck. Just because there is a Forscan option to turn it off, doesn't mean it was there. I can probably go into Forscan and enable FX4 features, and I don't even have 4x4.

If you hear a sound difference, with an upgraded sound system, then the only logical thing would be - signal noise being picked up with either the wiring running to it or the RF it produces.

Think old school - AM wine / hum through the speakers.

I can guarantee that it was there in my 2019, because my aftermarket sub decided that it was my favorite song.

I got it turned off in Forscan and now it actually works as a sub instead of a fake engine noise amplifier.

But then with these Rangers and how much Ford changed things on the fly, YMMV.

BUT why would you delete engine sounds?

I say ADD MORE SOUND! Only $39.90!

Including farting, perfect for dump runners!

I am very curious as to what exactly - The Fake Engine Sound -I want to hear the actual sound others are complaining about.
Is it just labeled as such, but as I suspect tied with the ANC and it is just picking up dirty electrical noise - I believe most of the issue arises from - it is a digital signal being sent back to the AMP from the ACM, I guess I need to take a deeper dive for this as I have not paid much attention to this (issue) only read the various complaints.
I was curious and checked with Forscan and Forscan shows mine disabled, when I checked it after purchase.
I would have to dive deeper into the install threads, but I seem to remember others having to do something with the ANC.

Here is the ACM - Hex Code Breakdown (As-Built Data)

I can only speak for me, but I didn't really notice it until I added the sub and it was front and center.

I at first thought it was alternator noise since it varied with RPM, and then someone pointed out that the fake engine noise can mess up the audio signal.

Disabled in Forscan and the noise immediately stopped.

It was *definitely* there on my '19 Lariat FX4. I want to hear what my engine is actually doing, so I disabled it via Forscan years ago, and there was a stark and noticeable difference when I get on the throttle. I didn't unplug anything or make any other changes to the audio system.

Ford may not still be enabling it, and/or it may be selectively enabled via trim level etc.

It could be a Lariat only feature, too. Who knows.

Ok guys so all key fob features still work on the truck including remote start same on my ford app through my phone. Truck still Auto Unlock’s when I walk up. I did test opening doors from inside without my key fob inside the truck while locked and the anti theft didn’t go off. Something I can ask a stereo/alarm shop about. I do know that I noticed the fake engine sound when my truck was completely stock it was subtle so I didn’t mind at all but after having my speakers replaced sub and amp added it was very loud on full throttle and sounded horrible. It is gone now but I’ll figure this other thing out now.
