Hello guys...i have a question..can i wired bosh lsu 4.2 o2 sensor direct to the ecu....as in this pic (white & gray) wire are goes to (a6 & a25)...so can i put the (black) wire to (d22) pinout... (Yellow) to (d14) pinout..(red) wire to any constant 5v key on engine on (koeo)..
P28 ecu code...
Thanks in advance...

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.

Can i direct wire the bosh lsu 4.2 sensor to that ecu pin out....i have read lsu 4.2 have 5 wire..
1.red(ip+)(d14)
2.yellow (ip-/vs-)(d16)
3.black(vs+)(d8)
4.white(heater-)(a6)
5.gray(heater+)(a25)
I dont need a afr guage...
I have read that d15z has use o2 sensor that has 5 wire and read 0-5v o2 sensor...LAF sensor...
Can someone help me please...

cannot.because ECU didn't have wideband controller per hondata said above post bro. what is you try to accomplish?

Acctually i want the o2 reading more accurate by 0-5v...i have reed that D15Z has use o2 sensor that reading 0-5v...
