O2 Sensor Simulator? Any one here have any experience with them? I ran them in my old S2000 and I never really had any issues nor has anyone I know, but I'm not very knowledgeable with the LT engine. I'm 99% sure that I've got at least 1 fouled sensor and rather than playing the guessing game or replacing all of them which would be kind of expensive, I'm looking at picking up the simulators from here: http://www.afterthoughtsauto.com/o2sim.html
Anyone have constructive thoughts and not just their opinion? Any insight would be greatly appreciated!

sims are for AFTER the cat only.
Autozone and the like will scan the car for free and tell you which sensor is dead.
If it is a front one then that affects engine fueling and can not be replaced with a SIM. If a rear one I would probably buy a new one and install it in the front and move the functional old one to the rear.
Last I bought O2s they weren't much more than those sims.
If I were looking to go down the sims route I would instead put the money towards a custom pcm reprogram that would gain you something besides turning off the CEL.

Isn't the Fast Dual Wideband using wide band O2s? I run the Fast XFI in both our cars in open loop and I use the wide band O2 to double check my tune.

Yes it has 2 widebands. One in the left and right primaries. Right now I just have one hooked up for analog. With the controller though I can either average or see the sensors individual.

Yeah he thinks he has a fouled sensor and instead of playing with them he wants to put in a simulator.
Just pick up new o2s.

54 bucks.

Just about everyone knows the Bosch narrowbands don't work worth a damn on LT1s, hell within the last month I even saw a technical explanation as to why.
Put some Delcos on there, they aren't bad if you get them from a good source like RockAuto or somewhere like that.

I just looked it up and it is $45 for AFS75 AC Delco O2 sensor. That is what my 96 Caprice uses. I am not sure why there are so many O2 part numbers listed or why some appear to have squatre conne ctors like some of the later model stuff.

I would look up the sensors elsewhere. I know my car uses the AFS75 in all 4 positions I do not know why the f-body would be any different.
I would never buy new after cat O2s if they are the same as the before cat O2s because if a rear one failed I would put a new one in front of the cat and put the functional but old one I just replaced behind the cat.
After the cat is only a tattle tale for the catalyst zero effect on performance or mileage, the before cat O2s will affect mileage and performance and they do wear out slowly so there can be benefit to replacing them before they code.
