Probably a slight error (for your car/setup) in the fuel Air temp correction.

Just stabbing in the dark..... Would it be the "'air density compensation for load and ipw" table?

So today the cruise AFR's drifted from 15.3 to 17 between the morning and afternoon commute... So bad that I actually pulled over and added 0.7 To richen it up.

I tried modifying the table I named above, but no matter what I try to change it to, it changes to 0000. so I left it alone. LOL
