I am trying to find info on using the data logger on the MPVI for my 2018 Sierra. I can't log unless I have my laptop. I saved the file, wrote it to the interface (just as I have done many times in the past for other cars) and only a few PIDs are in the recorded file.
Not having much luck searching over the last week so I wanted to post to see if there was an issue with Gen 5 or something I am doing wrong.
Thanks.
