Terrible timing on 2g log

[19BLACKGST98]

Yep, STFT is Short Term Fuel Trim, whereas, LTFT is Long Term Fuel Trim.

As for the O2 sensor running 0.82v, I just use that as a guideline. If I remember correctly, he had replaced the O2 sensor prior to those runs, which means he was running lean. If it was an older O2 sensor, I wouldn't have given it a second thought. You really want to tune by timing and airflow, not the front O2 sensor. It's basically only used as guideline and shouldn't be something you base your tune from.

Did Jeff set up your chip to trip the CEL at a specific knock retard?

For WOT runs, I look at airflow and timing to determine knock, since we can't log knock on the 2g. Well, at least we couldn't until recently with Ceddy's new logging program. Basically, you look at timing, corresponding airflow and the SAFC's correction factors, then compare them to the 2g airflow maps. Any deviation, barring a pull from IAT or coolant temp, and you know you're knocking.

That log looks good, except for that point at 6.5k, but I can't be sure without looking at the airflow numbers. You might have just got dropped into a higher airflow map.

What boost are you running?

That is not my log that is the log at the top of this page that I was using as an example. I did a few pulls on evoscan (which shows knock...1 count on my pulls) but I dont know how to post it? I have another logger that Ill try later if I cant figure it out. My CEL light is actually my shift light and it comes on at 7500 rpms. My factory boost guage is set up as the knock guage and it went up during my pulls (it is from being to rich though...lots of popping I had to get off of it at 6000 rpms) I believe mine is set at 21 psi...I know my electronic boost controller has low boost set at 18 and High boost set at 21 psi for now (that was for just 93 oct only). Once boost hit the tires spun until I shifted will that effect the way it is logged? (I wont put my DR's on until the car is where it needs to be)

Again thanks for the help.

PS: I know that the knock is from being to rich because my mechanic set it to where it was rich after 4000 rpms or so (becuase I wasnt supposed to be beating on the car anyways while I was breaking in the TRE tranny)

We I wanted to get a few pulls on my Palm using Palminstien and OBD guage but my palm is messed up (the screen isnt aligned and it is so bad I cant get to the settings to alingne it) so I just ordered another one that should be here in a week or so. Ill post some logs then.

Your rich from 3k-6k take out some fuel there.

Everything else looks fine.

I agree, your timing is good!! I would do the above & bump up the boost & review the logs from there.
