I have something weird going on in my tune that I have not seen before. Intermittently my commanded A/F will go from 14.64 to 16:1. I have gone thru my cal and I can not locate anything that would be commanding it to do so. My open loop commanded the entire time stay at EQ 1. What else is there that I am obviously missing that could change that commanded value? I am at an absolute loss on this one....
