You could consider running the car with no hood. Im not sure what your local laws require though. But it might give you a quick answer to your problem.

1997 S10, 06 trailblazer SS LS2 swap, 4L70E trans, 76mm turbo. Factory ZQ8 suspension. 3.08, G80 w/a zexel. With a 0411 swap.
I'm not sure on the MAF/IAT location, but I was thinking the O2's looked insane in the log. Are both of them completely out of wack or just HO2S11.
Slows10,
I don't think there would be an issue driving without a hood, but I'm not sure how much that would really tell me. If you see the 2nd log where, I started off having major issues. The car is cold, intake temps as well as engine bay temps are basiclly ambient temps.
I know HO2S11 looks real bad..I was not 100% sure on 21..
Is your O2 location manifold or do you have headers? Did you solder or stretch the O2's or do anything unusual to the wiring?
I hate to even suggest it, but since your car has been on the edge of detonation for so long..what would a bad valve do to your O2 sensor pattern?
I don't know what a bad valve would do. My O2 are located about 10 inches off my manifolds. My wiring has been the same on the O2's for weeks, but the bank 2 sensor (the one that has started pegging out at + 25, is still being ran off the analog wiring for the WO2. I'm thinking I should pull the WO2 and try a log using my stock O2's. They only have about 4000 miles on them.
Now that I think about it, I wonder if the LM-1 is malfunctioning and sending a bad signal to the bank 2 O2. Early when I was driving home I gave the car about 50% throttle and for no reason at all the LM-1 restarted and and started the warm up phase again.
Try the stock O2's for awhile. I have had a wideband for 2-3 years now..and those sensors can be challenging to keep calibrated. Stock O2's seem to be able to take a lot of abuse.Originally Posted by Gjohnson
That's a good idea GJ..
Well, I've got the wiring and O2's all swapped out and I'm ready for the drive to work tomorrow. Although, I am a little worry now, because if she is leaning out pretty bad I won't have a gauge to know it. Hopefully all will be good. I'll probably just baby her all day long.
HO2Sx1 voltages look wrong.
On which bank was the LM-1 simulating the NBO2 (was it bank 1, left/driver side)...?
The LM-1 was simulating bank 2 (passenger side). So, I don't know. I've got a log from the drive to work, but I can't post it until I get home since I'm logging with the V2 now. I wanted to get a log on my lunch break durning the heat of the day, but since I'm so short handed at work I won't be taking a lunch. I will cap off with a drive home, it should still be good and hot outside. Weather channel shows it should still be around 96* at 6pm.
Ok, I've got the logs from the day. 1st log was from this morning, the 2nd log is from the ride home. I really don't know how to read the O2 sensor voltage, so I'm really not sure if I was running lean or not.
