Delta Force Special Forces tuner allows you to turn off rear o2s and I think the SCT preloaded files still have that in the user adjustments as well , if replacing the cat doesnt work , sell the Diablo and use that money to buy a different tuner
OK wait... you were having problems with a CATTED x????? I missed this tidbit, catted, highflow should not be throwing codes by right... unless BBK isn't meeting emissions standards with the cats they ship with the product...
BBK is right, there should be no codes being thrown... bad cat or bad o2 sensor is my honest guess... Or this is a 96-98 correct? with 4 cats from the factory? I guess its possible to throw a code going from 4 to 2 high flow, but I honestly can't see it.
Even with my catless prochamber w/out eliminators or a tune it won't throw a code for ~400km if its warm, 150km if its cold (sub zero)... /W tune it will not throw a code (obviously).
Mil eliminators are NOT guaranteed to work. In 85% of scenarios they seem to, but I know of people who they haven't worked for.
I am with BBK on this one, I feel like there is a puzzle piece of information missing...
With aftermarket cats you can get a cat effecency code, some cars will never have this issue but a lot do after driving for awhile with aftermarket cats. this is because the aftermarket cat might meet the federal standards but it does not meet the standards in the ford EEC. the parameters for the cat effeciency monitor is for the stock cat converters that are more effective at removing emmisions.
BTW typicaly it's cars operated in cold climate areas that tend to throw the cat codes in the winter months.

That's interesting! I'm your neighbor in CT I'm tempted to just put on a off road pipe and keep the catted pipe for emmissions time only. I have the MIL's coming from AM, so the light will hopefully go away.
When I did my DIY Eliminators I followed the instructions in the link below...I later learned that the instructions were backwards...they show the resistor on the gray wire and jumpimg the cap to the black...at the end of the same thread they correct it and put the resistor on the black wire and jumped to gray...so I had to redo them...I was hoping I didn't ruin them by wiring them the other way first.
I figured I probably did, if you take a look at the link I posted it has the placement of the resistor on the wrong wire at first, later in the thread it changes.
no answers because anyone fooling with the stock system will be sent directly to jail CT is as no joke read up on inspection control they even scan your iris if you are doing inspection ! an attempt tp bribe a mechanic is a serious offense !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
um... where in the world did you get your info from? CT is a joke. I have no emissions stuff on my car with no problems. I stripped the smog pump, egr, etc. The only think i do for emissions is throw a catted h-pipe to pass the visual at the time of the test, hand them $20, pass.

and you drive a fox i presume since your talkin bout smog pumps and junk, the op has obd2 emissions style connection for some sort of emissions test. so he just cant hand em $20 and wam bam its done, if its here like nc its all central linked to the states computer, we have 2 styles of inspection (1) os safety only thats for 95 and older cars and trucks (2) is safety+emissions, this is were your obd2 port is used to detect codes, MILs, etc; thats on 96 and newer cars and trucks except hd trucks. oh and if you havent heard the states inspection is mandated by the epa which is a branch off the federal government. so any federal law that is broken will result in fines, loss of inspection license, and possibly JAIL time if they feel they want to make an example out of ya.

Nothing got damaged--guaranteed, the voltages and current involved here are tiny ( 0.2V to 0.85V and 0.02mA to 0.1mA); and the PCM input for the O2 sensor has a 10k resistance.
I found out after the initial posting that people were relying on the wire colours in the photos (just some wires pulled from the junk drawer), rather than the schematic diagram, to make the MIL eliminators.
Having the resistor on the "wrong" wire does nothing except make the RC filter ineffective.
Here's an oscilloscope trace showing a properly wired MIL eliminator:
The MIL eliminator is doing what it is supposed to, reducing the amplitude of the sensor's output from 0.8V pk-pk to 0.05V pk-pk (-24dB at 4.0Hz)
Here is the effect of reversing the components:
Note that the MIL eliminator output simply follows the sensor output.
