Default Insight needed

I've been having an issue with my 05 STi, the IAM's won't come up to 1, they're sitting at .875. I did some logging today but ended up with a lot of USBSER.SYS bsods on my laptop so I only have 1 good log. To make it worse I missed throttle opening angle parameter so I don't know how useful it is without that. If I need to make another log please let me know.

I had new stock injectors installed along with a DW200 fuel pump about a month ago. I also removed the in-tank fuel filter and relocated it up front like it was in 04 by the washer fluid. No other power mods. Its idling and accelerating smoother than it was but still IAM's won't go back to 1 and I'm concerned.

Does this log provide any insight as to what might be wrong? I see knock, but is there anything else that might provide a clue as to why it would run lean? On a previous road test with a local tuner a large AFR dip was observed on multiple WOT pulls but they were unable to provide any insight as to why. Any help is appreciated.

Are you on a stock map? Are you tuned? The table is a f'd up on my phone not being in .XML format. Either you are seeing true knock or you have something loose in the engine bay to only be able to get IAM to .875.

Stock map, not tuned. I'll see what I can do to get a log in .XML.

Thanks!

I would suggest finding someone else with a good running car and swapping MAF's.


Can you log "final fueling" its available in my 07, that's why I ask.
