2G LC-2 Wideband Calibration

[Bedicine]

Hello,

I've got a 2g and trying to wire in the LC-2 Wideband with a gauge and the other connection for ECMLink. I believe i have everything installed correctly but when i start the Calibration i cant get the light to go solid green (Sensor is heating up).

I have it wired as follows:

- Gauge /Controller Power from a 12v switched (back of radio)
- Ground i'm pulling from the back of the cigarette lighter as it seems to be stable
- White wire on back of gauge to yellow wire of controller
- Brown wire from controller going to front 02 sensor on ECU. I cut and soldered the wire at the ECU
- Dimmer switch for gauge is running off the cigarette lighter light
- LC-2 Controller
- ECMLink V3
- Battery is brand new Odyssey PC925
- WB gauge from ECM as part of the kit

Did i wire the brown and yellow incorrectly

It's been a long time since I wired mine up but I believe I used the yellow wire and tapped into the gauge and ran it to the ECU. Make sure that the ground for the gauge and the LC-2 are sharing the same ground as your ECU so the gauge and computer read the same. If you ground to a separate point, sometimes the gauge and the ECU don't match. Just FYI.

Thanks. Both feeding off the same ground, not sure what would stop it from calibrating

Bad sensor.....???? I notice my LC2 is taking longer to warm up and start reading than it used to but IDK why.

Just called innovative and they told me to change the ground to the engine block and make sure I’m getting over 12v first. If that doesn’t work they told me to give them a call back and it could be the sensor

So after I had the wideband connected I had some issues the day after. I’ve since grounded the unit to the engine block which is connected to my grounding kit and feeds the negative on the battery. Also have added the relay setup as per the instructions which pulls power straight from the battery. Switched 12v comes from pin 12 on tje ecu which is what they recommend and goes into the relay setup. All of this and I can’t get the sensor to calibrate. Gauge is flashing 7.4/7.5

Yellow wire from the sensor is connected into the ecu for the front 02 sensor (factory one removed) and I have the white gauge wire tied in with this as well. Brown wire is taped off

Ordered an aftermarket o2 sensor on Amazon that people have used as a replacement and I’m getting the same issues. What else could it be?

 

[Bedicine]

Looks like I need to run the brown wire to the front 02 location for narrowband. Do I connect the yellow wire then to the rear o2 pin at the ecu?

 

[Bedicine]

Checked power going to the controller and it’s getting about 13v.

Got a new LC-2 and installed it, was able to calibrate the sensor right away.
