Hello  first i want to adjust boost to 1 Bar. it is the AEB engine, throttlebody by cable. already mounted is a k04 turbo. can someone explain how this ecu works. this ecu has no map sensor. for the maps i think i have all necessary to start. - also mounted, wideband innovate and EGT gauge digital. logs with ori soft: boost 0,4 Bar lambda 0,90 EGT 880°C all hints are welcome. thanks |

Nice - first post and too many questions :-D First is other than need to adjust to 1 bar ;-) MAP sensor isn't important for good tune ;-) Do you have basic knowledge about remapping? M3.8.2 is some difficult ... But if you have WB so let's play with that  |

I think maybe FKTU, but without proper docs I don't really know. In the OLS file there is FKTU.0/FKTU.1, so I'm really not sure why 2, but both maps have the same value. In your file 76DC and 76EA seem to be correct addresses.... if in fact that is constant. ******I'm not a professional, just throwing out ideas****** Maybe someone with experience tuning constant in earlier Me can verify...

You need KHFM, it converts airflow in kg/h into pulsewidth in ms.

You use stock injectors? i think they are very small injectors on the AEB motor stock

How good is your german ? if you use the searchfunction, you will find a .ols project
with ALL important functions defined.. in german.
Tho people posted the file as M3.8.3 file.. which it wasn't. But still very helpfull for
converting 80% to M3.8.3. (flashable younger brother of M3.8.2)

Injector constant is Grundanpassungskonstante, tune it using the physical formula.
You know the stock injector flow and fuel pressure, after you fit the new injectors (and/or FPR), recalculate the flow and adjust the constant. It is linear.
Don't forget to adjust injector lag time.
You will need a VR6 MAF, take the linearization maps from a VR6 ECU and copy paste.
The boost is controlled according to MAF. It does not have MAP sensor feedback, instead the "pressure" table is really a target load table. It still has N75 duty map and limitations.

Could you explain please us Grundanpassungskonstante calculation physical formula ? Regards, |

K04-15
He meant K04-015, K04-020? I know there's different ones that fit. Should be on the data plate. Edit: I must be seeing things, it says K04-15 in the post above^^  |
