How does a 5.92/3.83 calculate fuel related to temperature differences (after fully warmed up)? I couldn't see a map that uses the IAT for fuel correction when warmed up. It does use the IAT sensor for warm up maps though.
1. Does it just use MAF?
2. MAF + IAT sensor to compute fuel?

I have seen that M382 uses a MAF/IAT map --> KFFMLTA 5x8 Gemischkorrektur durch Luftmassenstrom und Ansauglufttemperatur. I have looking for the same one for M592/M383 without luck. I have not see a similar map yet.

it´s on the exactly samy spot as M3.8.2, just before KFLFLAV, but ins a little 2x2 map

Forget to say, if you are geting unknowm enrichment when using higher gears (for example you have 0,83 lambda in 3d gear with let´s say 60 C and when in 5d gear you have 0,78 with let´s say 80°C) this will not help you.

Hi Junior you are right, do you know why that behavior occurs? |

Don´t know for sure, see some guys changing Tair sensor from manifold to inlet and get much more stable lambda values... with FMIC you get much less deviation when using a larger chinese SMIC |

Checked KFFMLTA - It only affects a small portion of the map. (when below 20c and low-mid load)
Do we have a voltage correction map, other than TVUB?

That is the reason I have the idea that it shouldn´t be KFFMLTA map there and should exist other bigger MAP in other location in dump. That way (2x2 applied below 20c and low-mid load) is almost useless. Just my idea. |

The 592 has the same exact map in it. Haven't checked the 383. 592 KFFMLTA is at 97EF |

5x8? Which ECU HW/SW? 8D0907557N & 8D0907557P? |
