High LTFT but normal STFT Diag - 330ci

[GiosBMW]

I was doing diag in scanmaster elm, My LTFT are 20+ and get a little better better in high rpm but my STFT always stay within range (check pics). I have already replaced the fuel pump, filter, and checked fuel pressure. All is good. My MAF readings dont increase at high RPM though, is that normal?

I wouldn’t keep driving the car at 20+.

Tell us about your maf and do you have vacuum leaks?

My maf is fine, not throwing any error codes, and the reading are within normal range. I have not done a smoke test because I wanted to see the fuel trims first. I don't think its a vacuum leak because the STFT are normal and stay normal with load. Plus the LTFT doesn't drop with load.

Ok start smoking testing all points.

What brand of fuel pump?
How many miles does the car have?
What codes?
Are the pre-cat o2 sensors original?
How many miles on the CCV?
how did you test the MAF?

high ltft is a problem regardless of stft. Yours are astronomical.
