First Start Issues..
If your narrowbands still aren't working properly after you check wiring (and maybe recheck after looking at the wiring diagrams on the forums like last time...) then be sure to check fuses. When I was trying to get closed loop up and running after several weeks of open loop only in my turbo setup, I couldn't get my o2 sensors to work anymore. I even went and bought new ones even though my old ones were working when I disabled them in my tune. Tried my old tune again, tried everything. Turned out I had blown a fuse when I made an extension harness to move the passenger side one. I felt so stupid.
