effect of CAT on WBO2 readings?

[joe graham]

>Hi all,

How much (if at all) will a WB measurement change if the sensor is placed
post cat (tailpipe probe), as opposed to pre cat (header bung)?

Thanks,

The cat is a second combustion source.  There is no direct correlation 
between pre and post cat readings as this would be based upon things like 
convertor efficiency and if you have AIR pump.  Is you have a working cat 
then only the pre-cat readings should be trusted.
