It isn't a dumb question. I just can't figure out what the question is... if it was dumb I would have answered  |

lol , i was looking for a map to add fuel when its cold in the morning and the car isnt fully warm (coolant gauge at the middle but ic's still cold )because on boost onset and spike i lean out a little and its only on the first pull of the day . i read the description really fast and didnt realize i was in the boot tab and not fueling.
Anyways i upped the load (ldrxn) like you said and it worked perfect. throttle is now opening to 100% earlier
not sure if you can see my wideband fueling but when i do a pull my fueling drops into the 9:1 afr range till i really start getting into boost . i was taking out fuel via fkkvs , should i use a different map to combat that?

I wouldn't use fkkvs for that, the problem is somewhere else in the fuelling maps. |

https://s4wiki.com/wiki/Tuning#Idle_LTFT_and_idle_misfiresIf 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:[15]

actual - per wideband . i dont have a log of it because once i see it climbing past 12.5 i let off dont want to get to lean . i was probably overboosting slightly and that might be causing it . bringing load on earlier help with the the bit of boost spike i was seeing before so maybe it wont do that anymore . ill try tomorrow morning these are from the drive home today . i adjusted the early rich condition with fkkvs . i know you said not to but i haven't found my issue yet . i went through fueling and compared to stock. not alot was adjusted other then lamfa and im asking for slightly richer then stock at the early rpm so i adjusted that back to stock . other then that i haven't added fuel anywhere to the lower rpm ranges. I did set up frlfsdp (running returnless with a stock b6 s4 fueling system) and that might be causing the super rich condition. also yes i know i need to take care of the 2 rich spots and lean out over all   |

Looks like you are hitting a load cap.
May need to pull req boost or underscale your MAF a bit.
