P3 gauge/wideband integration?? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

My question is..
Is the P3 pulling it's afr from the front O2?
I'm wondering if you could use a wide range O2 in the rear location and view it on the gauge somehow.

Sorry if this isn't the proper section. I just figured nobody outside the FI section will have much interest in this topic.

The P3 has 2 analogue inputs so yes you could wire a wideband to it if it has a 0-5v or similar output.

Yes you can, P3 have instructions on their website how to set it up. Any UEGO that has an analog 0-5v output will work.

I replaced my second O2 sensor with a wideband(innovate LC-2) and wired it directly into the ECU.

I'm debating if I should just do a wideband gauge on its own, or the p3 with wideband wired in.
The p3 is "neat" but I think it's a gizmo for lack of a better term.

I'm doing a wideband on it's own with extra bung welded in before the cat.

I also have a P3 and I bought an Innovate LC-2, but I haven't installed it yet. Do you have any instructions? Did you follow a DIY?

I ran the Wiring from the O2 through the firewall just behind the glovebox. Then I used the cigarette lighter behind the glovebox for my power and ground sources. Then you only have one wire you have to wire into the ECU which is also right there behind the glovebox. I'll try and find the link to the thread showing which wire to replace running into the ECU. It was a blue wire with white stripe.

Here is the picture showing where to wire in the O2 into the ECU
