[Diy_efi] wbo2 questions galore

[steve broski]

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
