Disabling Active Sound Enhancement (ASE) and Active Noise Cancellation (ANC) on 2016+
 

Hey Everyone,

I picked up my 2016 370z Sport (Bose, no Nav) last week and immediately got annoyed with the active sound enhancement.

I haven't found much info out there on how to bypass or disable it, so I'm hoping someone in the community might have some knowledge.

My understanding is with the Bose, there is a separate amp powering the low ohm speakers. I'm a bit of an audiophile, so not totally opposed to redoing the whole system if that is what it takes as a last resort.

If ASE/ANC can be turned off by the driver, instructions to do so should be in the OM. My guess is that it would be done through the radio setup.

Another member mentioned that the dealership was able to turn off ASE/ANC on his 2016. If it turns out not to be settable by the driver, take to a dealer.

Yes. I saw that thread. However, it doesn't provide a solution. There are also no settings in the radio to accomplish it.

I wonder if there is a fuse you can remove. I know nothing of the system, I own a 2010

On BMWs, there is a fuse, but there is also a way to program it out with a bavtech cable. Is there a wiring diagram anywhere for the Z?

As for the active noise cancellation, I believe there are only two mics by the sun visors. Worst case, I just cut the wires.

Not sure either but I imagine it would be nice to have the ability to turn them off independently. The noise cancelling can be prett nice, wish mine had that to cut some of the tire noise out, hoping next tires are quieter.

No there isn't a way to turn it off. If you pull the audo fuse in the Z your head unit will not turn on.

Where are the amps/processors located in these cars?

See the FSM. Link in my sig.

Might check the hidden menu, that's where the option is on the 16 maxima. Hold setting button then turn volumn knob till you get tonthebhidden menu and then it is in the config area. I forget exactly where but there is a YouTube video for the maxima.

This is from the 2016 AV service manual on p.85 for the Bose wo_Navi section. If I interpret this correctly they can be turned on and off.

This looks promising.

Do you have a link to the AV manual you referenced and where your screen grab is from?

There is nothing in your signature that links to an FSM for the 2016+. It would be helpful next time if you provide specific examples. Thanks.

Found a link to it: http://www.nicoclub.com/FSM/370Z/Coupe/2016/AV.pdf

TommyC33, just curious, I have not been able to detect any Active Sound Control enhancements and I've been listening intently. When are you hearing engine/intake enhancements?

I've rented a few Mustangs and it's pretty darn apparent when you fire up a v6 and hear a v8 rumble in the speakers... Stupid actually.

I've noticed it most under 50% throttle and up, and especially above 3k rpm. It sounds like the VQ engine, but like it was recorded on and played back through an iPhone or something with tinny audio.

I'm not in my car right now, but looking through the manual I can't tell if toggling that setting is doable through the service menu on the car stereo, or if you need a dealer computer to get into the menu...

That is for use with Nissan's CONSULT system, so the options may not be user settable. Any Nissan dealer should be able to do it.

My apologies for only pointing you in the right direction. I should have spoon fed it to you. :tiphat:

It was more misleading and time consuming than in any way helpful, because the manual you referenced in your link doesn't exist in the place you indicated. Anyway, I'm sure your intention was good and I was able to find it on Googles.

Off-topic, but is your username alluding to a C33 Laurel? :icon17:

No.

Where in MN are you?

I need to revive this thread. I just picked up my 2016 Z and I really can't stand the artificial nose being pumped through the speakers. Is the dealer the only ones that can disable it?

My FI Exhaust seems to disable any potential artificial noise in my '16 Z.

I guess the dealer is the only option then. Let's hope my local dealer can figure it out.

Hmm....
 

What I find kind of promising is that Active Noise Control and the Active Sound Enhancement are listed as two separate features.

I just assumed it was going to be an "all or nothing" deal to disable them. And several of the reviews I've read commented that the noise cancellation feature was actually rather welcome, as it seemed to kill some of the "drone" at highway speeds that earlier models of the Nismo exhibited -- which could get tiresome on long road trips.

I don't care for fake engine sounds being played over my stereo, but noise cancellation would be fine by me to leave on.

If you want to disable Active Sound Enhancement (and you cannot do it programmatically with Nissan CONSULT) you can unplug (or cut) the ‘engine speed signal’ from the Bose Amp. It's the pin 28.

Thanks for posting all this useful info.

Mine is going in for an oil change next week and i've asked them to turn off the ASE but to make sure they leave the ANC on.

If they can't manage to do it i'll disconnect that 28 pin instead.

I had ASE turned off and the car was so quiet I couldn't even hear what gear I was in over the OEM tyre noise.. was driving along at 4000RPM in 3rd half the time. HKS Hi-Power catback fixed that without being obnoxious.

With ASE off I've tried ANC on and ANC off (after successive dealer services) and honestly can't tell the difference. I kinda wonder if ANC is nerfed once you turn ASE off. But anyway, whatever. Would have been happy to keep ANC but the fake engine noises were awful.

Mine has an Invidia Gemini catback, which sounds fantastic but the poxy ASE drowns it out at about 4 - 5,000rpm and i'm hoping turning it off is an improvement. From what you say it should be.

I've been wondering what frequencies the ANC cuts out and does it cancel any of the exhaust note? I drive with the windows down most of the time just to hear it more clearly, so it can't cancel that out.

I bought my 2018 370Z about 5 months ago and sold my 2016 MX-5 that I had for 4 years and wish I had bought one years ago. All positives apart from the fuel consumption and fantastic value for money.

I had the dealer turn off the piped engine sound. They didn't even know it was a 'feature' until I mentioned it but switched it off easily enough.

At first it was a bit strange without it but only because it's unnatural to have so much sound from the engine at higher rpm and at speed. Now it sounds great and it's so good to know what I hear is real and not BS coming through the speakers.

I'm very tempted to go for more intake sound because that will come on strong where the exhaust starts to quiet down at the top end. I know the long tube cold air intakes make the best power but i'm more interested in the sound to be honest and wonder how much they produce tucked away in the nose?
Currently I have silicone intake pipes with drop in AFE filters.

I HATE that I am doing this - so after some failed searching and what not; I figured I would revive this thread than starting a new one.
After doing a 8hour drive by going to San Marcos and back on Saturday - I realized 2 things - 1. I'm getting older and the car is starting to 'beat me up' haha and I want to lower it (go figure)
2. I was forced to keep the speed on the 130 tollway to 80MPH (even though the speed limit is 85 for those not from TX). Between the exhaust, HFC and intakes - it is LOUD in the cabin due to the fake engine noise.

So - reviving this thread bc when I called the dealer - the service guy literally was like NO - NO we won't disable the Active Sound Enhancement. He acted like I was asking them to add turbos or a supercharger through the dealer. Anyway - so I KNOW it's pin 28 but I KNOW there is an old thread where someone was showing a diagram of the amp and where pin 28 is located etc within the forum. I know it's probably a stupid question to ask - but does anyone remember that thread by chance and can give me the link?

Again - i did do a search - but I guess I am sucking today at 'googling' haha - thanks in advance for any help. I'm a complete newb when taking stuff apart so wanted to see the diagram if someone can remember it before attempting anything.
