WEIRD logger readings... help!

[Sephroth57]

i have a palm and tuning software from www.pocketlogger.com, i set it to log and took it for a run. ran 2 times up to top of 2nd gear, went back home. i checked out the log and here are the interesting stats...

highest RPM run
7068 RPM
23 Deg Timing
02 sensor 1, bank 1 (front o2) 0.04v 0%

highest 02 reading
2716 RPM
29 Deg Timing
02 bank 1, 0.18v 17%


im new to tuning and logging, but this run seemed weird also, this was just cruising. at this point the stats were:

4148 RPM
38 Deg Timing (WTF??)
02 bank 1, 0.00v 0%




also i didnt want to cross post but my problem has tuning and engine elements to it, i only put the tuning part here so the tuning gurus can help out. i have the full thread in the engine section here: http://www.dsmtuners.com/forums/showthread.php?p=1022676#post1022676


any help would be greatly appreciated!!

so ive pretty much determined that my front o2 is dead. the question is what will that do? would that have anything to do with my boosting problems?

also what are these CEL codes all about.. and how to fix them?

P1400 Differential Pressure Feedback Electronic Sensor circuit Low Voltage
P0125 Insufficient Coolant Temperature to enter Closed Loop
