need to know if my o2's are bad or is it a fuel problem

 

What are the symptoms of your problem?

 

hesitating at low rpm cant really go wot yet cause im breaking in a new clutch along with motor,
has new icm, coil and opti. I changed the plugs from nkg tr55 to tr6 with a .040 gap because of the 12:1 cr of the motor and it ran better for like a week and then went back to the low hesitating from 1k to 3k with light throttle


engine is lt1 383 with LE2 heads with xfi280 cam

so i think its the o2's, map or bad plugs

 

You need to upload the entire file to an FTP site, and post the link. The data you copied and posted is of limited value, without the rest of the log. Its obvious you have a problem on the right bank, because the PCM has used the long term fuel correction to pull fuel, its bottomed out as 108 - which is as low as it can go with stock tuning - and pulling 15% of the fuel. The right LT pops up, but without the columns that show RPM, throttle position, cell #, ST's, etc... there's not much you can learn from it.

What software are you using? If you can produce the log in .csv format, anyone can open it and view it in Excel. Same with a .txt file, but its a bit more of a PITA. Most scanners produce a proprietary file format, that only people with that software can read - e.g. DataMaster .uni file format. But you can export the file in .csv format.

 

Yea im using datamaster right now i'm trying to upload file now will post in a minute

http://uploading.com/files/e4e39cm8/data%2Blog.csv/

file is short becasue im waiting on some OTVC wires to come in so car is down

 

need help please if the log is not long enough i can do it again on tuesday when the car is back on the road

 

You need to post the full log, not just the same few columns you posted above. Here's my guide to what to include in your DataMaster log:

Record# (inserted automatically)
TimeStamp (inserted automatically)
1 – Runtime
2 – RPM
3 – Speed
4 – TPS Volts
5 – TPS %
6 – MAP
7 – Cool Temp
8 – IA Temp
9 – Ign Volts
10 – IAC Pos
11 –AFGS
12 – Spark Advance
13 – Spark Retard
14 – Knock Count
15 – Inj BPW Left
16 – Inj BPW Right
17 – Fuel Trim Cell
18 – Left O2 mV
19 – Right O2 mV
20 – LTerm-LC
21 – LTerm-RC
22 – STerm-LC
23 – STerm-RC
24 – CCP DC
25 – EGR DC
26 – Baro
27 – IAC Tgt
28 – Idle RPM
29 – Inj DC Left
30 – Inj DC Right
31 – <OFF>
32 – <OFF>

That’s about the most useful set of data. You enter those in the positions 1 – 32 that you get on the Export Engine Data setup screen.

And don’t forget to enter the last record number of the file in the “Count” field.

 

ok give me a minute and it will be up

lets please have some good new by morning

 

You need a CONTINUOUS data log. Looks like you are siimply taking a "snapshot" over a variable period of time. You have incrememts between records as low as .3 seconds, and as long as 79 seconds between frames of data. You should be recording at a constant sampling rate - up to 10 times per second (0.1 sec/record). The value of the log is to see how the PCM is responding continuously, and trying to pick up the points where things go wrong, then looking back at the last couple of seconds of data to see what changed. I get logs as long as 20,000 records over an hour of driving. They are time consuming and arduous to evaluate, but they give a better picture of what is happening.

Based on the very spotty data (37 records):

Right BLM (learned long term correction) is bottomed out at 108 (deducting 15% fuel). INT (temporary short term correction) is pulling out another 80% fuel. The right side is totally screwed up. I can't remember all the details of what you have done at this point, and I don't have the time to go back andread through the thread. Have you tried swapping the left and right O2 sensors to see if the problem stays on the right side (wiring or engine problem) or follows the sensor to the left side (sensor problem)?

It looks like you only included the "target" idle RPM, and not the actual engine RPM, which I asked you to include. The IAC is just about closed, with counts as low as 1 at idle. You also didn't include O2 sensor volts, which I asked you to include. Appears you didn't really make an attempt to follow my suggested content. I'm trying to help... but you have to make an attempt to work with me.

What is the elevation where you live? MAP of 88kPa would indicate you are well above sea level.

 

thought i included everything, like i said i will post another log on tuesday with 15 to 30 min of run time and will send you the uni file if thats ok with you

 

Send the .uni file. That way I can export it the way that I want it. It takes a lot of time to set these things up so they can be analyzed, beyond what DataMaster graphics provide.

 

ok will get back with you on tuesday or wednesday at the least
