Hi. Thank you very much for joining me to the forum! During the pandemic, I had a lot of time so I decided to make my own ECU powered by the wonderful RUSEFI firmware.
Recently I was able to connect everything to the engine which is the M54 from BMW. The car runs great and reacts to throttle pedal, unfortunately I have a problem with the fuel. I cannot go down to a mixture less than 10AFR. My VE map is very low. I have no ideas what could be the reason. I used the last firmware (2021 May "Piercing Day") with only modified pin mapping. Greetings!!!

Re: Fueling

Re: Fueling
I've edited your post for the second time removing screen shot of tune.
For second time I will ask that the way to request help is by using https://rusefi.com/online
I am not excited about editing your post for the third time. I am blunt and not nice but that's a requirement - take it or leave it.

Re: Fueling
Have you got a returnless fuel rail on the M54?
If so one of your ways around this might be to add a fuel pressure sensor.
