    O2 sensers not reading in log

    Hey, I have a 2005 Chrysler 300c and can't get the O2s to read when using the vcm scanner and was wondering if anyone has any suggestions. I tried repolling supported parameters, resyncing, deleting and reinstalled the software and I checked over the wiring as well as tried new sensers. Ill attach the log
    Thanks, Cameron
    also, I have long tube headers and I'm only running the the primary o2s
    log:

    first tune idle.hpl

    there are no 02 sensor v channels showing in the list

    chose the sae channels

    they have to appear in the channel list before they will have a chance of connecting to the pcm

    the fuel trims are not reading because it is in open loop
