LC1 Wideband install w/pics

As long as you have both parts in this screen configured properly (tell the ECU where to find the wideband signal at the top and bottom sections), you can input the wideband in place of the rear o2 and use the narrowband simulation without a problem.

Do I need to lock rear o2 voltage? The sensor is physically located in the front but I'm using the rear o2 input.

Yes, the box should be checked. I think it might automatically check when you associate a wideband in the top portion of the screen.

From the program's help:

ECU Input Locks for Factory Code

Check these boxes to force a hardcoded value for any of the defined inputs.  This function is useful when connecting an aftermarket sensor to an ECU input.  In that case, you generally want to disable the ECU normal use of that input.  For example, if you connect a manifold pressure sensor to the EGR temp input, there's absolutley no reason to have the ECU continue to sample and try to interpet the EGR temp input as an EGR temp sensor.  So in that case, you would check the Lock EGR temp checkbox.

I just installed an LC-1 wideband In the front O2 sensor position and tapped into pin 76 to log in Link.

I was wondering if I need to leave the terminator plug in the input wire or remove it. If I understand correctly I'm not going to use the In/out wires since I'm logging with Link, but does it matter either way?

Leave it in. I actually wrapped some electrical tape around it and the wire to make sure it stayed in place.

Great, thanks for the quick and simple answer. I'll probably run it under the dash so it's out of the elements.
