Could someone point me to FR module which is responsible for engine start up rpm (just after engine start)? I've looked into LL* modules but haven't found info on that there

From the s4 wiki:
You can bump the idle/cold start RPM as well:
KFNLLKHM - Elevated idle RPM until motor is warm
KFNLLNST - Start RPM (momentary)
I think you should be able to locate them in the FR

I know these maps. Closest (KFNLLNST) has some sort of delay before starting. I thought that it would start just after crank but it takes around 1s to actually kick in. I'll have to check ASM I guess.... Unless someone has a clue |

I took a quick look, and I am not really into the FR, but I see tnst that could be a source of the delay? It is hooked to many other functions though...

tnst is the time after engine start. I have 0 column and it doesn't fire up instantly. Maybe I'll try logging if there's maybe some sort of rpm filtering that is actually limiting the requested rpm

I'm trying to create initial 2200 - 800 rpm sweep on start up as you can see in supercars  Almost done with KFNLLNST (when setting axis to something like 0 1 2 3 4 5) and first column rpm 2550 (FF) all others 0. Though sometimes it lags a little before firing up the sweep. |

I have 0 in first column. Strange is that today it fired up instantly but yesterday delayed for <1s. Anyway, I guess since today everything is OK I'll stick with KFNLLNST and call it a day |

Nah, just novelty just because I've already done everything that we do here usually I thought I'll try to find some new interesting and untested things. |
