    Default misfire logging

    Hello,
    I am chasing a cold start misfire on a 2008 GMC Yukon XL (6.2L). I am logging the typical parameters and the current misfire PIDs (MFCYL1C through MFCYL8C). I could be doing something wrong since the MFCYL*C PIDs are getting values of zero. I am using V8 software and a FlashScan V2. A couple of log files are attached. Thank you for any help.
