When you open the log file in DataViewer, you will need to choose (or create) a dashboard to view its contents which lists the PIDs from your log that you want to see. In this case, the Engine Speed and two Knock PIDs are relevant (I just chose Default_GM dashboard and modified one of its tabs to show the PIDs I just mentioned).

I have attached a screen shot of what this looked like when opened up in my DataViewer instance.

From what I can tell, there is some knock occurring in the log, as both the Knock PIDs show values greater than 0 at various points. You will need someone more familiar with reading the output from a GM log than me to tell you anything useful beyond that though.

Speaking of GM, the DCX sub-forum is for Dodge/Chrysler specific tuner posts, so you will probably get more feedback if you start a new thread up one level from here, in the General in-Tune forum (http://www.diablosport.com/forum/viewforum.php?f=44) where others running the tuner on GM vehicles can see the post and provide feedback.

Good luck,
Nuke
