First Log, Now I Have Questions

[alex99gst]

I just recently got a datalogger and wanted to check and see how everything was running and if I was getting any knock I didn't know about. As it turns out, I ran into some problems when doing my first pull. This log is of a 1st - 3rd gear pull in which consitently, through every gear, I would get to a certain rpm (about 4500-6000) and I would suddenly feel a big slam like I just busted through a house. My power would end quickly and I wouldn't be able to get any higher than that particular rpm range in that gear. This happened multiple times where I couldn't go past 4500 rpm's in 3rd gear. I am assuming that my O2 sensor is by its consistent readings of 0.06v I remember reading that the timing being measured can only reach 43* on the logger, but I seemed to have hit that mark. My mods are listed and I am only running 14 lbs of boost. Any information or suggestions as to what the problem could be is appreciated. I attatched the log text file to the bottom if this is illegible.

Your o2 sensor is dead

 

[kraka]

No knock is good, but without any fuel mods, a s16g at 14psi might trigger enough airflow to hit fuel cut..Also, that 02 sensor is definitely having issues

For the next log, try to just do a 3rd gear pull ONLY

I had a log of an only third gear pull, but it looked the same as that one just with constant build ups and then sudden drop offs Ill get a new O2 sensor and see what happens. Thanks guys
