Hi Wesam,
There was an issue in one of the recent updates where some SAE PID scaling values were not being stored correctly in the log file (AFR, MAF and MAP). In the log file you posted the MAP scaling is set to 0 which means "use default SAE scaling". I presume GM have defined a custom scale for the MAP PID in the C7Z06. If they have defined a custom scale for it then it is not being recognized correctly by the software version that you are using to log the data. I recall fixing that issue in a recent update.
Have you tried the latest beta software available here:

If you are already using that version, try logging with the V8 pass-thru scan tool or with the FlashScan in standalone black-box logging mode.
Regards
