You have a nice tool. I cannot believe it isn't capable of displaying data stream. Most will display data stream but not be able to display individual graphing.

Regarding your last question, unable to answer until I see what you provide.

 

I had same problem, finally fixed problem. High pressure fuel pump leaking fuel into oil. After having same symptoms you described car begin to not shut off when I turn the key off rough idle. High pressure fuel pump leaks gas into oil. PCV valve pulls the vapors out of the crankcase into the intake, that's what my problem was hope it helps somebody out
