I'm interested in using a PLX wideband o2 sensor for my Kpro but need some advice on what I need. Can I just buy one of these?

And if so, which sensor type? Or do I need a controller too, like this?

Will a wideband sensor run in place of one of my existing o2 sensors or will I end up with three total? Lastly, what do I need to do to wire a PLX wideband in place.

 

wow no answers? I thought i saw a thread where someone rigged a wideband into the Kpro board

 

you need the wideband and controller and something to read the data with. none of your links worked with me so im not sure.

the wideband can be set up a few different ways, some people choose to always have it installed and run the simulated narrow band to their ecu, or others just to tune with it,etc. im sure the kpro would tell you more info.

 

well def get the PLX, all other widebands, especially the aem are actually off by .5 give or take

 

I run the modded Kpro with RSX wideband as well as the Wideband from the PLX.

When I was getting this setup done, we found that the PLX wideband does not work properly with the Kpro (voltage reasons?). So I ended up getting the RSX wideband for the Kpro, and kept the PLX one just for the gauge.

 

How did you have the PLX plugged into the Kpro? I've been told using the PLX through the Kpro through the analog ELD input should work fine for datalogging. I just bought the SM-AFR for this very purpose. If you were trying to use the PLX as a primary sensor, that wouldn't work.

 

I think everyone is over analyzing this.
Why do you want a PLX so much?

Just buy the RSX o2 and call it a day. The Civic one is actually $50 less even.

Here's my reasoning:
When you go tune at the dyno, they will use their own wideband anyway. After adjusting the A/F, timing, etc, they will also correct the offset for your oem o2 according to what they are seeing on the dyno.

Now if you're going to tune yourself, it's a different story.

 

Right, originally I was trying to see if I could leverage the PLX wideband to serve a dual purpose as I already had it on my car, then found out it wouldn't work with Kpro as the primary O2 sensor, so I bought a RSX one instead.

 

RSX o2 is not PnP on 00-05 S2kpro. Not sure about the 06+.

If you want a WB for the 00-05, you have to install it seperately and connect it how I referenced earlier.
