 Subject: MIL Eliminator

Message:
Sorry for the double post, but i figured this would be seen more in this as opposed to the V-8 section.
I posted a few days ago that I was throwing a P0420 code which means "catylist inefficient". With help from people here I have figured it is because I have an aftermarket Cat that obvioulsy doesn't work very well. I mean, you could look throught it. I didnt really expect it to work.
I have a hypertech, so I can clear the code, but it comes back after about a week of driving.
I would like to test the voltage on my O2 sensors, make sure that at least the front one is reading an acceptable voltage, and then try and eliminate the rear one.
What I need is the voltage for the front one, and the difference that the computer is looking for from the rear one. I have read on here that they make a rear o2 elominator, but havent had any luck finding one.
Please help me out.
And please dont tell me to do a search. I have,and turned up some things, but I need more. And this search engine does a horible job of sorting and filtering

I've heard they're not super difficult to make so if you got some knowledge in that kinda stuff, save yourself some cash...
I don't think you can just set your downstream 02 to a certain voltage to fool it. I think the voltage has to be flip-flopping from like .1 to 1.0, .2 to .9, etc... if it's not, I think it'll throw a code or run really rich.
