Well with the ongoing rich, fuel flood issue with my car I decided to take up data logging with my SCT after talking to my tuner, I'm still waiting on a response from my logs but I pretty much data logged in at idle with some revs, and granted I'm no where near on top of my game when it comes to interperting the values from the livelink data log I did notice something that stood out rather immediatly. I picked my bank 1 and bank 2 front oxygen sensors as two of my items in the log and I immediatly noticed that the bank 1 sensor is reading .003 to .000 sometimes with some occasional spikes in the .100s. Why the bank 2 sensor is reading .400s........... This stands out as a rather big difference between two sensors I would imagine would have close to the same readings so I think a jukey 02 sensor might be causing me this massive headache I've been chasing for a week or two now. Is anyone good at interperting these data logs because I have some MAF, and Spark attributes selected as well but don't really know what to make of them... if so I can PM over the logs.

What format are the logs in?

Hmm cany remember whatever format the sct livelink saves in

Repzard

I just check the format and its .csv - comma-separated values

I believe it can also be opened with MS Excel.

Hopefully thats all thats wrong with your car, o2 sensor is simple engouh to fix

Uber, PM them to me and I'll take a look.

The PCM would interpret that low voltage from the bank 1 as a lean condition and in closed-loop mode try to correct by making the short term fuel trim go positive to add fuel.

I really hope so Cliff, because its throwing no codes and this thing is driving me friggin crazy and not knowing much about data logging that stood out as odd to me and it sounds like that might be the damn problem, I also have to check my extensions cause I bought 02 extensions for my long tubes.

Well I'm certainly no tuning genius but I've stared at more than a few data longs. I'll look at them if you'd like.
