If you know how to make it do that then please help there thanks

That is really choppy. You have alot of knock, do a boost leak test or turn the boost down. If you have a SAFC your gonna need to add some fuel up top. I believe on the bottom while your logging your can change the preference and get #'s instead of a line graph. There should be like 5 little icons under the graph, press those and see what happens.

Yes you definitely have a knock issue, it might be phantom knock. Try checking the condition of your knock sensor and see if there's goo coming out or anything. How much boost are you running? Also try to get coolant temps, intake air temps, and tps reading on your next log.

Your o2 voltage also seems way out of spec, most tuning places I read suggest .92v~ so you might wanna check to see if your o2 sensor is hooked up right and all that.

Let us know what happens

p.s. I've never used DSM pocket logger but look for a "csv" (comma seperated values) option.

Ok performed a boost leak test and deffinetley was a leak and i fixed it . Thee boost was jumping to 20 and falling off to about 16 . Now it will jump to about 17 and hit fuel cut?

Turn the boost down to get rid of the fuel cut. Also your boost hits real late, did the boost leak fix that. Also when I log the data is seen at around 100rpm increments not 250. Also dont even log the narrow band 02 it tells you nothing. He could have a bad sensor if its that much out of wack?

Yeah, my only question is, will a poorly performing sensor like this affect driveability?
