I am still using v92 software and firmware. I put in a 4gb memory stick (ntfs format) with the parameters set to log at above 3500 rpm. I selected the channels to log and resaved the session file and commited the changes and unhooked the pc from the tuning usb cable and did multiple pulls beyond 3500rpm. When I try to import the log data from the memory stick it shows no files so does the pc still have to be connected to the infinity to use the usb logging? I looked for directions in the pdf instructions but it they dont go into any detail on how exactly to use this feature. Thanks for any help.
