Horrible o2 readings!!!

[DSMRomEo]

I'm getting an o2 voltage 3.26-5.00v. i'm getting kinda pissed, could a boost leak be causing these. Maybe a bad o2 sensor? my timing went as high as 217 and 43 counts of knock. Sorry for not searching but computer time is limited where i'm at right now, otherwise i'd post a log. I believe it might be a boost leak that i've been looking for, any help would be appreciated.

Are you sure you're reading the right o2? o2-f or o2-r?

Correct me if I'm wrong but O2 sensors aren't suppost to read over 1v in a normal OEM narrowband sensor. Sounds like to have a problem with you sensor. Also if you timing was at 217 degrees you would be firing your plugs on the exhaust stroke. I don't know much about knock counts but I have always been told that anything over 20 is deadly to an engine. I would suggest making sure your readings you are getting from your datalogger are correct.
