ECMlink Front o2 not cycling after Lc2 install

[Jacolu3]

So I noticed after my lc2 install my o2 is not cycling. Link is detecting it and reading it accurately but my voltage stays at .8 volts the entire time I'm driving.
I've checked and I'm not locked in open loop.
My Wideband is located in the front 02 location.
I am using the input pin for the rear o2
I have the drop down in link for wideband as front 02
I also have the nbo2 enabled at 2.45 volts.
Any idea why my o2 doesn't cycle after a 10 min drive?

Thanks
Brian

Did you calibrate?

 

[Jacolu3]

Yes I did calibrate

If its located in the front o2 then should you not have it pinned in the ecu for the front? Not the rear? Sorry i dont have mine in NB sim and just run mine seperate in the DP.

When I tapped into my harness I used a wiring diagram that was labeled wrong so I tapped into the rear o2 instead of the front. But I didn't think that would matter as long as I sim narrowband

Youre tapped into a totally different circuit and you didnt think it would matter? Im confused.

I asked this question a few weeks ago and someone said as long as you tell link where to look it wouldn't matter

So your running the lc2 signal into the rear o2 input. Why would you tell the ecu to expect the signal to be coming into the ecu at the front?

 

[Jacolu3]

I guess I was getting conflicting advice on pin assignments. I'll have to try to switch the pins tomorrow

This is why I didn't replace my front 02 with a wideband sensor.

I put my wideband sensor in my exhaust.

AEM FTW.

I was under the impression you could use one of four pins and you tell link which pin you used so it can read the wb. Then when you want to simulate nb you tell link to use the front o2 to simulate.

 

[SasaniFab]

its really simple. You pick and output on the ecu that is unused. I.E I used the egr output on my 1g. So if you have a 2g it sounds like you want to use the rear o2 as the open input for the lc2. Now if you still want to use your oem front 02 keep that as factory. Your basically telling the software to expect the o2 signal from the wideband in the factory location.

Post a log so we can see what you are really doing and if the setup matches what you've done with the hardware.

this log was superlean. At the end i locked it in open loop and it got better

 

[Jacolu3]

this log was locked in open loop and the car ran much better

Try telling link on the ECU input page to use the rear O2 input for the Narrowband simulation rather than the front O2 you have it set to now.

 

[Jacolu3]

I actually disconnected the wire going to the rear o2 pin and just soldered it to the front o2 pin and changed the settings in link and all seems good now.

I posted a new log with the changes with a short full throttle pull toward the end of the log. Had a little knock. Around .7
