You need to make sure that all the wiring is correct. Trace each wire as needed until you are sure of what's connected to what.

The plx was wired this way. All I did was tap the wb into pin 4. What else would use the oxygen signal? If I can't trace them, should I unhook them and where there any kind of heat stip insulated in the harness?
I'll be taking another look when I get home, just need your opinion on what to do if I can't trace.
In particular, make sure there is *nothing* else coming into the ECU input other than the MTX-L output.
That ECU pin should only be hooked up to one wire - the yellow wire from the wideband. Anything else (including those grounds - no idea why they are there) should be removed.
Nope. Still seeing that 1.15 second sample interval.
Last log. Is it still the same and what I'm I looking for?
That definitely looks more like a wideband in the 06 log. What does "no default response selected from the factory" mean?
But...now your simulated O2 signal isn't firing consistently.
EDIT:
Your CombinedFT is maxed out, and the simulated O2 is only switching when AFR drops low enough to cross the trigger point. You need to add some fuel or raise VE cells enough to get the fuel trims within their working range.
When I went to look at the response time setting, nothing was selected, so I checked 1/12. Do I need to 0 out combft and fuel sliders, then go from there before I add fuel? Ecm set link up at 315 deadtime, but for fic's it says 350, do I need to change that also?
Well went ahead and zeroed out combft and fuel and took a cruise. There is also idle at the end of the cruise starting around 245.470 of the log. Got combft down, and airflowperrev needs to come up. Let me know what adjustment to make. I'll post back tomorrow, I've had enough for today. Thanks guys. Oh yea the 02 sim is working now also.
Im still seeing your fuel injectors set up for 693cc and base fuel pressure of 43psi. You also need to set your prefrences so that your afRatioEst matches the wideband. To do that right click one afratioest and edit the prefrences for min and max. Then do a idle log and get your airflowperrev up and your combinedft close to 0%.
You also should zero out your timing sliders.
Looks ok to me. Go do a cruise log and report back. Try to stay steady on the gas, I tend to do a log at 30mph, 50mph and 70mph, keeping it as smooth as I can, then right click and select MafCompAdjust to give you the recommend points.
Your coolant temps are at 213 do they drop after a while when the fans come on?
No, I'm talking about the actual WB signal itself; not the front O2. His LC-1 is putting out the wrong waveform for an analog WB signal. The voltage is correct, but the waveform is wrong.
Normal WB signal:

OP's WB signal:

OP - Have you changed the programming in the LC-1? I'm not familiar with it (or what you can do with it software-wise), but it looks like you are logging a narrowband signal that for some reason is switching in a 0-5v range. I have no idea why this would be, but it definitely looks that way.
