New, How do I livestream data?

Well I'm new, and I don't plan to write tunes or anything like that. However I have reflashed a couple of Duramax powered trucks and want to learn more on how to use my V2. I figured out how to load certain pids onto the v2 so I can look at them with the v2 connected to the truck. But how do I view live pids on my laptop while the truck is running, and connected to the v2 and pc? I feel really stupid for asking how to do this :/ lol

Start V7 scantool, click connect button (upper left, green circle), goto PIDs tab, select pids, goto Dash letter tab, click record button (bottom center, red circle).

Also take a closer look in the scantool user manual pdf.

Thanks! So I can data log that way also rather than black boxing with just the v2?

Yes.

The 24 channel PID limit still applies for fast data logging.
