Trying to wire up my innovative wideband to my s300 in a p28. Read mixed reviews about this wideband reading different then the s300. To use d14 for o2 and d10 for eld and stuff about removing resistors. I need a more steady answer.

 

I mostly use D10. if you plan to use D14, remove R136 and R138. Those resistors make a resistive divider and limiter, the input cannot read over ~3.8v

 

Alright because I just tried d14 yestarday and it was erratic.

 

That is incorrect. I advise against using D14 as is does not read correctly as stated above. The resistor mentioned above must be removed if using D10 which is the recommended input to use.

Closed Loop Advanced Parameters

 

Good info here. I was also wondering about this.

 

I have zero issues using d10 with the resistors removed, did this on two cars recently no problem.

Reads full 10 to 20 afr with my plx, whereas d14 won't read above 17.3 or so.

 

what model innovate wideband do you have, what version s300 do you have?

 

Should the lc2 power wire share the same power wire as the ecu?

 

I'd recommend it's own line from an option port on the fuse box or from thr battery, fused of course.

Grounding it to the ECU will help any potential differences though.

 

I did it exactly as Spunkster recomends. For some reason it seems the Hondata employee who runs the Hondata forms seems to really know Hondata systems REALLY well.
