GR86 Fake Engine Sound On/Off Comparison 

You went from stock to an even quieter exhaust? Do you live in a senior community or what?

@@Heinousness I commute 80 miles a day. A loud exhaust soon gets on your wick, believe me. I love that I can hear the engine.

What exhaust did you put?

@@Teefs143 I wanted to retain good flow for the supercharger but get the noise down, so I had a Hayward & Scott stainless steel bespoke exhaust made with large silencer and twin Helmholtz resonators. It flows so well my power was slightly increased, too.

@@martinwtaylor interesting, you're BRZ is 2022 with 2.4L right? Never seen it with supercharger. How much hp it got?

Same how i felt about the induction sound tube in the first gen. Annoying on the street, but useful at the track.

yeh, something like simulating F1 car downshift noise would be cool

@@TrackandBuild is it actually possible to upload your own engine sound?

@@Briguy288 probably not but you can create your own ASC unit to play whatever based on the car input signals (throttle, brake, and etc)

It's a great video, but its disliked because that's the popular thing to say...its a social media cliche honestly. For NEW enthusiasts leaving it on so they can hear the engine better makes more sense, because regardless most people are supplementing the lack of ASC with a louder exhaust so they can hear it inside. For someone not doing that just leave it....

​@ftr911drvr not entirely true, I disliked mine because I could sense the lag of the timing for the fake noise and it would throw my shifts off. I turned it off and put a louder exhaust on and now I don't mess up shifts like I used to

yes, like you said exactly

@@TrackandBuild Please do a how to video

@@TrackandBuild Could you please make a video on how to do it? I need to do this on my brz! :)

Update: the red wire did NOT work, but the brown (ignition) did !

This is my problem too. I disabled it because it was too loud and obtrusive. However, if I could modulate it to 50% or "Off" as needed like some Lexus models, I wouldn't have messed with disabling it completely.

in normal mode, ASC is just quieter

i don't mind ASC also lol it's honestly not loud to the annoying level

yes exactly:)

@@TrackandBuild Thanks! That gives me some good ideas (or bad ideas if you ask my wife).

Would you consider posting a DIY video with the details. ASC switch is an excellent idea and should be a good video.

Yes it's just a switch to the wire

Nah it's pretty bad

No the fuck we won’t

No

I personally prefer the fake sound

You're right. It gets a lot of hate but it's a not bad solution to "me want vroom vroom real loud" without making the car deafening to everyone around you. If it keeps even one kid from drilling holes in his muffler it's probably worth including in cars. But I do wish it was on a switch like this. Cruising with a passenger on a long drive I want it off for sure. But going for a fun driving session I might want it on instead

I think it's a dedicated speaker behind the console for the fake engine noise. You probably could tweak it to control the volume but I haven't tried

@@TrackandBuild I think that would be the a simple way to control the sound, access to it I imagine would be difficult, or you identify the speaker output wires from the sound generator and attenuate the volume it through a speaker volume control box, a physical volume controller wired inline from the generator to the actual speaker, then you can adjust to suit individual taste

Excuse the grammar, it’s late

@@johnybigarms Yes, I think others also mentioned the idea. It might work!

@@TrackandBuild Did you find evidence of that speaker, or are you just guessing? I was thinking that maybe part of the sound module wiring harness/connector is a simple speaker output, but it looks tricky to put a scope on it and look for things that seem audio-like. Somehow I think it's part of the CAN bus in the car, and may be piping (digital) sound to the main stereo/audio unit of the car. That's just a gut feel, no actual evidence on my part. I WISH it were a speaker somewhere, because then it should be fairly easily to get a variable attenuator of some sort and control volume to wherever one likes it. Even better, low-pass filter it so that you only get the low notes, since IMO that's the best part of the added fakery, since the car doesn't inherently (stock) have much deep to it.

I did not try that but it might work!

It'll only be audible once you're over 4000rpm - once you're out of the break-in period and it's safe to start beating on the car, definitely do some pulls in it and you'll be able to hear it more clearly.

@@JDMFlipFlops okay thanks for the info. I was wondering if it was 4000rpm. Nice to have it confirmed!

I could definitely hear it before 4000 rpms. It’s very noticeable. Disabled mine today

@@timmcintire9402 Kind of strange as I can't hear it below 4,000rpm. Maybe I've been driving too much like a granny though hehe. I'm certain I have it, and I will probably deactivate it the moment I actually hear it after break-in. EDIT: You know for a thought experiment. I should just open it up now, and pull the wires, even while still driving below 4000rpm, and see if I can notice the difference. I'll do it this weekend.

@@Jez4prez1 or it just doesn't bother you, I think some of the reactions to it are pretty dramatic honestly

Here's a document with the pinout docs.google.com/document/d/1369m2NF14v76D-8E0EwOBejsj2yOJVyvgjNiU5J297o/edit#heading=h.rguruzk1rs0o

@@TrackandBuild Thank you so much, this is fantastic and very detailed

it may sound louder in the camera due to the mic position.

Yeah that would be cool

I did not film while doing this one. Definitely will post when possible

@@TrackandBuild ty!

@@TrackandBuild Yup, please tell us which wire you're "switching" that is not throwing a code.

@@robertpeet1360 simply add a toggle switch on the ignition wire of the ASC unit and you got it

not that I know. ASC is louder in track mode than in normal mode though

@@TrackandBuild can track mode be used for daily driving? Or does it loosen the grip on the road?

@@JamesTonerUSA i always have it on with sport mode u should be good

@@JamesTonerUSA I think track mode just disables ESC and TCS, so you will actually gain more usable grip from the chassis, but also if you make a mistake and slide it won't help you out any.

I put the mic close to the glove box so it sounds louder
