Have bit of a funky cold start on G8. At 58 seconds into the log you can see target lamdbda go from .66 to .85
Also seem like MAF readings are a little funky, reads 4000 hZ at 900 rpm there and then at 1:45 at idle its reading 5400 hZ almost, at the end its 3600 hZ
IVT table doesnt have any sudden jumps like that to cause target to be that rich at first then switch?

Almost looks like an afterstart diagnostic. Try to do that again but don't move. Just sit still, no pedal input. And get IVT and anything catalyst/o2 related.
ecm20221 is enabled see if disabling that helps
