I flashed a stock bin to the car and I can see that it's only trying to access the first cell of each axis, which leads me to believe that there's somehow either a hardware issue or this ECU never had a working KFKHFM in the first place. Here is a video of what I'm talking about: https://youtu.be/Utx8VPZ-Gt8 Map tracing appears to function perfectly for KFMIOP as an example, but KFKHFM is mostly stuck at the top left aside from a few odd blips. I did also log rl and nmot, and they appear to be perfectly normal. My logs also show that the MAF voltage does spike when I have the rich condition, so this does appear to just be some odd turbulence in the intake causing the issue and as I understand it KFKHFM would normally be the correct place to correct it.

As for actually correcting my issue, from what I can gather the FR shows that KFKHFM should always be active in turbo engines and it uses only rl and nmot as inputs (which I logged, and both look perfectly normal), so with a stock bin file I can't think of a reason it should be inactive at any time. However, I've seen some discussion floating around that certain ECUs just don't have working tables to correct the MAF.

Could my ECU be one of these, in that even though the table "exists" it's not functional? If this is the case, do I really have any options besides a wideband ME7 or standalone conversion?
