I'm modifying a file from an unknown tuner for a customer- When I got the car, it had part throttle LTFT's disabled because N80 was removed but not taken out of ESKONF. After confirming that fuel trims were enabled, I changed a few things in the file, and lost fuel trimming again. Not just LTFT, but all off idle correction. I narrowed down the culprit to LAMFA, but I don't understand why. I could just start from scratch with one of my files, but I'm stumped as to why changing only LAMFA would stop lambda control, and only part/full throttle.

Attached are the working(a) and not working(b) files. Someone please shed some light for me. Maybe I'm missing an obvious flag that not in my definition?
