The OBDI ECU does not have a wideband controller in it. You can't connect a wideband o2 sensor directly to the ECU - it needs a controller.

I am planning to use bosh lsu 4.2 o2 sensor but i dont want to use the afr guage...the afr will only monitor in 'recoded/datalogged lambda (shift+f2)'...base in this pic...did u think it is reliable to pin the (red wire) to d19 or d20..(black wire) to d22 or analog gnd..(yellow wire) to analog 2(an2)...remove the r2&r3 to read afr from analog 2(an2)@b6....

It will not work. You need a controller.
