    Commanded AFR going the wrong way

    Would anyone have a minute to look at the attached tune and log? I can't figure out why the commanded AFR goes lean at heavy throttle but the actual AFR goes rich. I'd appreciate any help.VK56 Frontier change 5.hptchange 5 wot.hpl

    Thank you. That is what I'm looking at - it goes the wrong way. The measured eq ratio is good, but it moves opposite to the commanded. I can't figure it out.
