	Current AFR doesn't follow desired AFR « on: May 13, 2023, 01:11:28 AM »

Hello, so i ran into some problems when making some changed to ldrxn and kfmirl. After tweaking these 2 maps a bit, ive noticed that my current air fuel ratio doest follow my desired one. It seems to be running lean for some reason. Is there something I missunderstood about ldrxn and kfmirl maps and did something wrong, or is this something else ? My afr seems fine when i revert back the changes...

fr_w (lambda regulation) doesnt work probably due to some dtcs or something

its fine at stock but at higher loads with some fueling issues this could be the reason of lean condition

You are right. I made a mistake where i changed CWKONABG to 0, where as because it is a b6 it has to be changed to 1. That fixed the problem. Thank you
