Pardon me for just jumping in here... whats the problem with NB O2 sensors 
and why would you want WB O2's????

steve broski <sjbroski at msn.com> wrote:i want to replace both NBO2's in my 
S/C3800 GM with WBO2's. i found the
schematics and info at the WB-DIY site for using the L1H1 UEGOS. i thought
with some additions for another 0-1V out for PCM to control from, it would
work pretty well. however the cost of that sensor is a little. . .steep. the
bosch LSU4 can be had for about $40. much more doable. it seems the above
mentioned control circuit won't work. i can find no sources for specs on
LSU4. anybody have any info that might help? that would be really fantastic.
i have my eye on a sanner/tuner for my car that has 3 additional A/I's(2 for
WB and 1 for whatever i want)so i can do some tuning. thanks for any and all
help. steve
