    3.6 Traverse won't go into closed loop

    2010 Traverse retune6.hptretune5 drive.hpl
    I can't figure out why this thing is just staying in open loop. O2 mV stay between 840 - 870 mV no matter what, unless I lift my foot off the gas completely in which it drops to 0. Can somebody help me find what I may be overlooking? Gas mileage is terrible and it is my wife's daily.

    I am trying things that I think might work. But I don't know, so I'll let you all know.

    Hmm, that is strange - didn't think that you ever had to do a "Write Entire" under normal circumstances...

    Anyone know why that would be needed in this case?
