[Edit]: Why is your engine temp at 122F?
Yes, but in numerous discussions on EM that position has been debated, with the argument being that the ECU will compensate. But here, my UG is suggesting that the ECU is not compensating. That I am running lean, consistently. That surprises me, and I am wondering why it is so, or if I am misunderstanding the meaning of this display. ... the coolant temp is low because the car had been sitting for over an hour after running...

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
