Default Help me analyze my O2 readings and Fuel Trims

Help me understand,
ok, first off, my my long term fuel trim B1 differs from same thing B2 by a few percents, for instance B1 reads 2.3 and B2 reads 0, or B1 reads 7 and B2 reads 5.5, sometimes they are even.
Also Short term fuel trims, like B1 can be -2.3 and B2 -0.8, or like B1 1.6 and B2 is 3.9
Is it normal that all of these 98% of time are not even?

Do you monitor yours, what they should be? I'm using Ease software....

Yeah, that stuff will be forevermore changing. These 'puters are constantly learning and re-learning. It'll never settle down completely. If it did, I'd get worried.

Good luck!
