    KR that is only present during Changes in commanded AFR

    I have KR that comes in right when the commanded AFR makes a change. Even if I'm running rich...still there. Any ideas?

    Some more details: My AFR on my wideband is around 13 when the commanded is 14. Then, when it switches to a commanded of 12.5, the AFR drops down to 11.9 or so. But, in the same exact frame that the commanded drops, the KR comes up. It leaves as soon as the commanded goes back to 14

    Also, I don't think the advance it logs is correct, if you look at the base and the adders, it won't equal the advance that is logged
