I upgraded my 97 Yukon to the 0411 computer and 02020003 OS.

When It shifts into 2nd or 3rd it goes really rich and doesn't follow the commanded AFR.

Any ideas?

After further analysis, I believe it's from the torque limiting feature. I have it turned it on because it shifts so darn hard and I was trying to soften it up. When comparing logs the more torque limiting I command the richer it is.
