Default O2 Simulators

Does anyone have or know of where I can get a set of O2 Simulators for an LS3 (post cat)?

O2 simulators are pretty much history. There was a clamp down on vendors a while back and they pretty much disappeared. The current technique is to have your rear O2 sensors tuned out in the ECU.

If you can find a Preditor that has not been updated, it will turn them off.

If all you are trying to do is tune out the rear O2s and if you are in Dothan and if you want to make the hour drive down to the Destin area and if you will cover the $100.00 it costs me to license your VIN in HP Tuners I'll tune them out for you.

They were trying to shut Casper down for EPA violations.

Yes, the Feds made the company refund money to everybody that had bought them plus fined the company $$$ for basically tampering with the emissions control system.

Edit: Here's the story from the EPA's website:
http://www.epa.gov/compliance/resour...per-fcsht.html

The interesting part of the article is the end of the third paragraph where they state "there is no "off-road" use exemption from the pollution control requirements of the Clean Air Act." So I guess even if you build your car into a race car, you still have to have all pollution control equipment intact and working!

Wow! They sure as hell let them have it. I wonder what the total cost was for recalling all those sims.

I have headers and high flow cats. The rear O2s were tuned out.

Well, I took the car to the local Chevy dealer for warranty work and the first thing they do is plug in and see if the computer has been tuned. If they find it, they will turn you in to GM and void your entire warranty (everthing, the entire car). So, they called me and told me to put the stock tune back. And I did...

Now, without the rear O2s, I get a service engine light and the dealership sees that when they plug in. So, I guess I am going to have to put the rear O2s back and see if I can get the warranty done or find another way of getting it through their crappy warranty department.

I went to another chevy dealer and they said the same thing. The dealer has to get authorization to do the warranty work and they always ask to verify that the computer has not been tuned and is stock.



I hate GM. Buy a 60K car and you better not touch it or else

Anyway.. thanks for the help.
