One year is not enough, if you're constantly running lean that's not healthy.

I was looking if this tune is healthy or not in case of, but after one year, i think it is ok.

Understand,
So, i will try to find what happen during cold weather and cold engine to have this CEL.

When i'm checking data logging, i understand that no fuel pressure crash but as LFTF and STFT are quite high, it could be possible that i'm on edge of fuel pressure in this custom tune.

I will try to check with my tuner
Thanks for your help.

This was around the 8th revision on this setup. I was told that it "looks very healthy" and I am already starting to "run out of pump". The car runs almost the same times as before when it was DAW UltraFlow/Dorch DS2 setup.

What do you see needs work?

For a start, boost target vs Actual totally messed up and STFT way out of healthy range:

Do y'all think I'm running out of pump or injector?

Hi everyone

I would like you to check my logs and let me know what do you think.

The car:
540i gen 1
TU HPFP
Downpipe with 200c Cat
MHD stage 2+ 93 Oct

I plan to get XHP ASAP, so I have the MHD map with the option to run without it at the moment.

-Are the timing numbers ok or too low? Boost?
-Are the load figures normal?
-Torque. I know the map lies somehow the DME about the NM, but does it look ok?

Any comments will be much appreciated, thanks!
