Innovate LC-1 wiring

Alright guys this should be an easy one for you. Getting ready to hook up LC1 wideband and want to run it as both wideband and narrowband. The Yellow wire simulates narrowband and I'm wondering where that goes on my obd1 ecu? (correct me if im wrong on using the yellow wire to the ecu, just assumed it had to go there)

You'll need to have a chipped ECU to do this so you can disable the primary oxygen sensor heater. Once you have that disabled, you'll run the yellow wire to the D14 pin on the ECU.

Supposedly, you can run a 1K ohm 50W resistor in the primary oxygen sensor heater wire (A6 pin) to disable it. But I wouldn't want to do that on my car.

Some links with this info for you.

now im a little confused. After doing a bit more research I have noticed that people wire it to d7 or d10?

Nope. Even Hondata says to use D14. Here's a couple links to explain it in more detail as I now realize I was pretty vague with my previous post.

ok doesnt the brown wire need to go to the ecu also? I know it needs to go to the gauge. Thanks for all the help so far.
And as for the rest of the wiring for the old o2 im removing, just get rid of it?

According to what Hondata is saying, all you would need to do is connect the wideband signal to D14 and wideband ground to D22. Then setup the lambda conversion to match your wideband. So really, there is no need to even use the yellow wire.

I'm using the AEM wideband with the standalone gauge and Crome with the factory narrowband O2. So my experience with your setup is limited to the Hondata and Innovate instructions. I would follow both of their instructions to get everything squared away.

Thanks alot. I've been trying to read up.....All I gotta do is swap a few wires around. I should probably quit being a pussy and just wire it up. lol

well I've got it wired up and my afr isn't too bad.....10:1 at idle.....lol its horrible. I'm not quite sure how to fix that other than going to a tuner.

Can you adjust the tune yourself?

Just take some fuel out wherever you need to.

Do you have datalogging setup with the hondata (is it smanager?)?
