hey pretty new to all this but I loaded a base map on my ecu after I installed a acuity cai and it wasn't throwing a code at first but now I'm getting p0171 running lean bank 1. From what I've heard the maf sensor can no longer read the air ration coming in? But anyways if someone could help with a tune that would be nice to try and solve this issue. I data logged today on my drive to work but I don't know how to read these yet. Only other upgrade is a axel back right now.

The car has a few counts of knock so the timing needs to be adjusted. The trims are high in the positive direction indicating the car is running lean. Every time you max the trims you will get a lean code. You need to dial in the AFM to bring the trims back in line.
