Closed loop on Chevy 1 ton

With some help from Brian I was able to get the ECU to go into closed loop control. New O2 sensor. (I could tell my the sound of the engine when it went in). Not sure what parameters on this gauge cluster are not reading at optiumn. Can anyone see any problems.

i don't see anything too odd from that screenshot...

is there something specific you're having trouble with?

Not sure, have to take it for a test run and do some data logging. The gas mileage had dropped dramatically so I have to recheck now that I am running closed loop. Thanks for the interest.
