white smoke and sulph. smelll afther Stage 1 MHD
Hi guys i would like to ask for advice.
I have 10/2018 540 xdrive europe version with OPF standart catalyzator I use to tank 100 RON gasoline for my car. Afther flashing MHD stage 1 (there is no difference between ron 95 and 98 maps in term of smell ) my car stinks more, and realized there is much more white gas from exhaust. Iam not sure if it is rich mixture, but it stinks much more “sulphuric”. It smells much more even when if engine is warm I flashed standart map without burbles ETC. I replaced VCG but it doenst help. When checking bimmerlink afther test ride i have 0 misfires, no engine code yet , lambda values appears to be fine when idling and during ride ( around 1. plus minus 0,05. Engine is running fine. Afther flashing back stage 0 it is completely fine. I think even stage 1 the engine should not smoke and stinks much more as in my case. Any ideas ? |
