oxygen sensor location?

[Jon]

   Is there a consensus on a good location for the oxygen sensor in a 
true dual exhaust system?  I've been doing some research, and some 
people say to just stick the sensor on one bank, others say put it 
in the H pipe to read both banks, others say there isn't enough flow 
in the H pipe to get a true reading...  Its a bit confusing.  :-)

   I suppose it would be possible to use 2 sensors, one on each 
bank, just past the collectors, and average the readings, either 
via a digital circuit or analog, but I don't know if that is
really nescessary or not.  In my case, the fuel injection 
system is just a simple TBI setup, so the computer isn't 
looking to equalize the banks or anything, it'll just adjust the
mixture for the entire engine in closed loop mode based on one oxygen 
sensor signal, so I want to be sure I give it the most accurate 
signal possible.

  Any info or insight would be greatly appreciated.  Thanks!
