N55 Not reaching boost target on MHD Stage 1
n55 e92 xdrive
xhp 3 mhd stage 1 everything stock, only charge pipe changed for aluminium one. I have a problem with the boost target. I see from my logs that I am not hitting the boost target and the difference between actual boos and target is like 0,2/0,4 bar so like 3/4 psi. The car drives perfectly fine and i do not feel any lag. Today I changed all the gaskets/orings in turbo pipes and in throttle body (valve). I also cleaned the sensors and the pipes. After the change the curves look maybe a little bit smoother but the gap is still big... I know that some gap i acceptable but not such a big one. Anyone have any clue what can I do next ? As I checked all the pipes and changed gaskets for the new ones I doubt for the boost leak. Log 3d gear before change: https://datazap.me/u/zawislak/3rd-ge...=0&data=3-4-12 2 logs after the change https://datazap.me/u/zawislak/3rd-ge...r-orings?log=1... Update: I did the log o 3d gear with stage 0 map (stock power) and boost control is perfectly fine.. https://datazap.me/u/zawislak/3d-gear-stock-map?log=0... Basically now i realised that I reach more boost on stage 0 than on stage 1 Last edited by Zawislak; 06-18-2022 at 02:36 PM.. |
