O2 Sensor Trivia
Why does the car trip a Check Engine Light with the rear O2's disconnected even though they are turned OFF in the programming?
-and- Why do the Wideband installation instructions tell you to put the O2 sensor in upstream of the cats because it will give inaccurate readings if the sensor is placed downstream of the cats when all major dyno's use a Wideband sensor that sticks into the tailpipe? (I really don't know these answers, I am just asking)

I believe we have already discussed issue between 'tailpipe' widebands and real widebands. The tail pipe ones are not as accurate but at the same time I do believe they sample a little different.

Re: O2 Sensor Trivia
Yes, cat's burn even more of the unburnt fuel left over from the combustion process. And in the case of 93 and older fox bodies, the air tubes actually pump oxygen into the cats to keep them nice and hot.
However, at WOT, the cats don't work nearly as well. Don't know how, if any, differnent tailpipe o2's sample the air behind the cats.
