I stand corrected. Thank you for posting these videos. They clear everything up.
Hmm I’m really not sure, my cars roars in both cases just at very different volumes.I stand corrected. Thank you for posting these videos. They clear everything up.
So, the valves do not close after starting, as I thought, but actually they're already closed by the time the engine has started.
But then, this doesn't explain the initial roar, the first second or so after the start. If I start the car once in Normal mode and once with Quiet Start active, there's an obvious difference in the sound of the exhaust at idle, but the very first second of the engine start, the initial 'vroom', sounds the same to me in both cases. Why is that?
I am noticing this too, and I was wondering if it were my ears. Seeing how quickly the valve modulates (from youtube videos), one would think that they could set the valve BEFORE they fire off the engine. My first morning start on Sunday, the car was well withing the quite mode time, but it fired up loud, and then the bup, bup, bup, bup, of the exhaust for about 2-3 seconds and then it went quiet.
That's odd. My Quiet start is just that, quiet. You do get the initial higher rpm sound when it roars to life but that initial roar is always quieter than the other modes.
It doesn't. It stays in Quiet until you change it - either directly, or by selecting another drive mode.
What I'm seeing too but you can flick once to Normal Mode (which is where it defaults to on start anyway) but it does nothing. Must be okay but curious what others are seeing.
One flick just brings up the menu and shows you that you are currently in normal, you always have to double flick to get to a new mode. I have MyMode set up in track exhaust with normal drive mode, so I am always two flicks away from loudness.
Technically you could put the car in track mode and unplug the connectors / pull the fuse - however that will set an error message on the cluster and also not allow you to ever leave track mode on the fly.
That shouldn't be the case. Do a simple test to see what your issue is. Turn ignition on in quiet mode first (no clutch or brake pedal depressed, so engine DOES NOT crank), then go check BOTH valves. If they are fully closed, go start the engine. If quieter than before, you'd know what the issue is: valves are taking longer than normal to close. If engine sounds the same, keep investigating while watching the valves, to see what's going on.
Mine sounds the same, regardless if I start it the normal way, or if I hit the start button without brake pedal first and then start it.
More or less some people’s ae seems to not fully start in quiet mode as it should. The 350’s behave slightly differently. But on a non-350 quiet mode shuts the valves and leaves them shut until taken out of quiet mode. Other people’s ae it appears they don’t close until a second or two after start causing a very loud roar which defeats the purpose of the quiet mode. My .02 is that those people that get the initial vroom need to have the valves looked at under warranty and adjusted so it starts fully closed as they should.
