Can o2's really die this quick?

Check out my scan and you will see that it appears the one o2 just died. You will have to scan about halfway through the scan to where the car actually started. It's also an untuned cold start scan. Brand new o2's with about 15 min total run time.

Also some of your IPW and IDC look way out of line for the rpms. It would help if you said more about the car and post the tune that is in it.

It's a stock 2000 bin file. I havn't tuned it yet. I'm still learning all this stuff...my wideband should be here next week. Here's the engine:

2000 Z28, stock injectors, long tubes, true duals, LS6 intake, 236/230 .602/.575 112 LSA cam, ported stock tb, ported maf.

If you could help me out with a baseline tune I would really appreciate it. I tried loading a few tunes from the repository, but naturally they all have strange results.

I thought the injector stuff looked strange...especially when the duty cycle jumped to 116 at 3k.

No tune from the repository will ever make the car run right. Start with an OEM file and work through it accordingly, no need in chasing someone else's mistakes.

Oh yea, I knew that. I was jut trying to get something to make it run halfway decent until I got my wideband and could play with it. What's the best thing to modify first...iac stuff or ve?

But what's up with the o2 dying like that?
