MAF sensors also have a response time. Testing MAF response time requires a computer and some simple programming. Work to do here.

Would show up on a scope, but don't know if response time would indicate much.

LTFT not moving indicates it is happy with the amount of fuel it is getting. You stated like 2.8 and never moves, not understanding that unless all the driving is same pace on level ground.

On the highway at 55mph the control loops lean out and diverge a bit. Bank 1 -2.8% Bank 2 -3.9%.

Might get some other feed back from viewers, but interesting it is chopping fuel now that it is under load when idle had it at +2.8

Not mentioned yet, but should probably log all this when it happens and look at all the data that happens at that time.
