    VCM Scanner not reading 02 and STFT

    VCM Scanner not reading the 02 sensor B2 and STFT trims B2 all of a sudden, has anyone else had this issue while scanning? I have a 2014 Camaro SS with a stage 2 supercharge cam from Texas speed, forge piston, e-force supercharger and PRC Heads.

    Remove the channel, click vehicle at the top in the scanner and re-poll for supported parameters while connected to the vehicle. Add the channel back in and see what happens.

    Do that first before anything.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
