Quieter Cold Start

CantComplain · 01-07-2018, 10:31 PM

So, back to the topic at hand. Can the startup exhaust be coded to be quieter? I leave before the neighbors are up and want to be respectful. Also looking hard at a downpipe.

2017 6MT. I have bimmercode and in theory Esys. Can anyone point me towards a way to keep it quietish? I love the sound and look forward to the dp, but would really like the ability to switch it off and on.

You could always buy a Prius???.

While that solves one problem, it creates several more.

Anyone? Looking for a coding or tuning solution to disable cold start. I've seen references to being able to do it in ESYS but not the actual code. I'm looking for something other than the "Vietnamese mod" from this (although to be fair, that IS pretty sweet

).

Looks like bootmod3 can do it.

Like the guy above me said, if you tune your car you can remove the cold start procedure all together.
Unfortunately there's no way to simply code it out.

Get a 230i or move!

Ah thank you. This is the first I’ve heard someone say you can’t simply code it out. Others have said you could but never provided details. I’m guessing that the startup routine is buried in the ecu.

Waiting to see what MHD puts out and still have a week or 2 until the dp comes in.

Ho I want to do exactly the opposite, having cold start all the time

Usually open window slightly before ignition so I can enjoy it more

Keep your driver's door open during cold start and you'll hear it even better !

Seriously i love the M2 and i bought it for the sound, but i hate that cold start... Dont u wish it was more exotic like a high "roar" ?

stefan · 02-15-2018, 08:04 AM

These comments about moving or buying a prius are ridiculous. OP has a legit question. If you don't find the cold start absolutely obnoxious then this thread isn't for you. Frankly I find it incredibly annoying only to become a whisper after the first rev. I have MPE and if I want to make the car louder Ill do exactly that while driving. Shame you can't code it out. Splitting hairs on the emissions saving end.

If and when you tune your car, you can code in a start up roar! Its awesome! Totally changes start up for me.

krizze · 02-20-2018, 06:31 AM

I didn't buy this car to please the neighbours, i bought it to please myself. So catted DP from Akrapovic coupled with M Performace exhaust, valves open cold start, Good Morning Neighbours, me and my stupidly loud car wish a lovely day

krizze · 02-20-2018, 06:33 AM

Also to add to this, because i usually start my car drive 4 minutes to my nearest shop for a drink, i start it again, you get a really loud start and it uprevs on its own. this is only available from what i have tested when you follow this sequence above.

MZWIE · 02-20-2018, 11:01 AM

Why do people even make such inane posts.

Did u code it by yourself with a cable and a PC or an app ? Or do you have to go thru a specialist ?

I got my car tuned by VF Engineering, Its an added feature they give you. I actually made a video about it on their thread, you can watch if you want.

Well, I apologize if I’m turning this post inside out but does anyone have any tips on making the cold start even noisier ???
