Title: RS3 Style Soft Launch Control
Post by: armaan on July 21, 2020, 09:32:26 AM
Hi everyone,
I am back with yet another Noob question. (Sorry  :D)

Is there anyway to make our soft launch control sound like this:
https://www.youtube.com/watch?v=FMOPWKDnxDg

I have set my DNMAXH to 20 (and KFNWEGM to ~3500rpm) and it seems to sound like that for a split second, and then back to the boring old soft launch sound.

I am wondering does anyone have experience with setting DNMAXH to 0 with Soft Launch control, and does it sound like the RS3 above?
Or perhaps I could set KFNWEGM and DNMAXH such that it makes a sound like that.

Or if theres some other maps that I could look at? Any direction or help would be great  ;D

Need to post the rom. Post the ecuid or something. I can give you it for the b6s4 if you want lol. Rom would help stock version of it.

Hi sorry, I just saw this today.

Here is the stock rom from my car.

I am curious as to what map makes the RS3 sound like that?

someone correct me if i am wrong but i believe it more or less has to do with the fact that it is direct injection. so the two step method is a bit different

Nothing to do with DI.

I have seen our ME7 Hard Launch control, and my god thats violent as hell.

The soft launch feature shown in the video comes with the RS3 from factory it seems.

I guess the first step for me would be to check how different exactly it is from our own ME7 soft launch control.
Guess I was trying to look for a hackjob way of making the car 'sound like that', whereas I should have asked as to what exactly happens during that RS3's launch control: is it a mild ignition retard? or could it be injector overrun? (but not sure if DI injectors would spray that way).

What is the mechanism of that RS3's launch control? Is it just a dumbed down, emissions legal version of our own ME7 Anti Lag Launch?

Just thought it would be interesting to get to know it.

I'm interested on following/trying this! I have a 1.8T 06A906032KP to try it on.

It does not exist in ME7.
You need to write your own function for that.

But summed up it is:
* Late ignition (high torque reserve + low zwmin)
* 2-3 cylinder rotating pattern cut (redeta...)
* Shut throttle a little to control the rest (nmax with lower rpm limit)

You can do it just fine on non-DI.

Thanks! Will try when I get a little more comfortable with ASM, but definitely interested in trying to get it to work.

OMG! Thanks.

Hmmm I must get into this whole IDA, ASM, making functions thingy thing properly.
Hopefully if I manage to do it, after exams, will post an update here.

it's not just a "thingy"
enjoy days of your life reading. then more days trying. then more well you get the point. i wouldn't touch asm with a 10ft pole because i know my boundaries. i can use ida but god damn

good luck friend

If you do not have any extant computer programming experience (minimally in a language like c. Not python. Not java. Not c++), you will not get anywhere.

Ah I see.....
Ok, thanks for the pointer.
