    VCM Scanner not logging the same on two very similar GM E38's

    I hook my scanner to a 2010 Z71 with a 6.2 and everything logs great on a generic layout. I can unplug it and hook right up in a 2011 Z71 with a 6.2 and connect to vehicle. It only logs 1 O2, no injector duty cycle and few others.

    Does it to that even after re-polling all the channels on the 2011 truck?
    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.

    I don't know what repolling is, but it does the same thing when I hit connect to vehicle. I'm going to attempt to post the data logs from each truck here.

    Click the vehicle tab when connected to the truck, that is where you re-poll all the available channels.
