i would try checking connections + grounds with volt meter. If the 02 is not moving at all its not warming up thus no reading . A aem wb should bounce around at idle 13.8-15.6 afrs when 02 is cycling.

The wb gauge needs a clean 12v source and good grounds as well or they wont read right at all. NOTHING on the radio harness ... is acceptable

id pull the wb o2 out and check and see if that gets warm it takes a few min when it dose the gauge will pegg out --- means its working

now if it only reads 14.7-14.8 the connector is loose or possibly bad

i have had 7 of the ugo wb they all are picky and just suck +1 for innovative wb and plx


i do know the aem have narrow band sim its the white wire on the harness i think you set it to p04 and .90~.01 is what should be coming out

in link voltages up in the .98 is rich as hell .01 is lean

there are so many things that can keep it in open loop and is really no fun at all ... good luck ... if the car had any race fuel or any additives it will eat the 02 sensors up been there ...


and if your having trouble getting it to idle what are you active maf settings between 50-150 and timing readings . maf's do go bad and will cause bad readings make the car run like crap or just not idle

and if your biss is out of adjustment not enough air past the plate or too much it will mess with your and maf readings " kinda like having a vacuum line off "
