You need to determine what thread you want to proceed in with this problem.
Also I hate to tell you, the current scan tool you have is not likely going to be a lot of help. Unclear if it supports Live/Realtime data and you have to buy software to transfer info to a PC.
Spend less than $30 for the OBDFusion App and interface. This will run on your phone/tablet and will allow you to gather a great deal of data and post it for review and comment. There is not way you will be able to easily transfer the large amount of data from your current tool, much less Log OBDII PID data. Trust me, this is not my first rodeo and OBDFusion is worth every penny of $10 or less for the App. Yes you have to figure it out, but most people can get the hang of the tool within the first 10-20 minutes playing around with it.
You can chase some of the ideas you have based on this forum, but here is most of what you really need to know:
