From the S4 wiki:
Finally, if none of this works, you may have to increase your idle RPM and/or idle torque reserve (alters idle timing)
NLLM - idle RPM
NFSM - idle RPM while in gear
KFMRES - idle torque reserve
KFMRESK - idle torque reserve while transmission decoupled (clutch in)
If your car runs poorly while it is warming up (engine temps less than 85C-90C), you will want to tweak the warm up enrichment tables according to your STFTs:[12]

Are you using a electronioc throttle body or mechanical one with idle air control valve? |

OK...I am not sure but maybe you have to lookup for ETC opening at start based on coolant temperature and altitude above sea level... |

Every car does this from the factory. The Ferrari was cold... During cold starts the idle speed is raised, this is not reserved for supercars. |

I wouldn't go crazy high with the Rpms ....you know you have turbos probably not a good idea to go too crazy....I'd leave well enough alone

You can do that with *BBHKZ as I said earlier in this thread :-) I went through the code a couple of weeks back and stopped my car idling at 1800 for a few secs on cold start. It did it for cat warming but with a full exhaust it would wake the dead, not very nice to my neighbours on early starts. |

thanks, i dont thinking about it from that pov going to rtfm  ratherb1, yes i tell him about this first, but for some people those effects are much more important than a turbo life. his choice..  |

I think I understood what you want. In order to throw up rev after engine start (before entering in idle rev area) you should rise up KFMIRL in that area which you want to rise up env. |
