Hello. I'm wiring up my LC-1 WBO2 to the Datalogit, first time I've wired up a wideband setup fyi.

I have not started my car yet, but I want to be on the safe side as far as wiring it up.

I have calibrated the sensor and all is good so far.

I have the 6 wire version, i.e. no Green analog ground wire as I've read about when I have searched.
a. Red 12V supply
b. Blue Heater Ground
c. White System Ground
d. Yellow Analog out 1
e. Brown Analog out 2
f. Black Calibration wire

Otherwise I have sw. 12V wired to the blue wire coming from the fuel pump fuse (I have done the fuel pump wiring mod in the engine bay)

Blue, white and pushbutton ground along with LED ground all soldered into one lug and grounded at the trans tunnel (as recommended in the instructions) I don't have a gauge (yet).

The yellow output is unused, still run stock O2 sensor and will try this first as I still have the airpump.

The brown is connected to the AN1 input, and I have made a ground wire that goes into AN2 and I have checked off the Delta AN1-AN2. I have also plotted in the default LC-1 readings. 0V is 7,35 AFR and 5V is 22,39 AFR.

Is this correct, anything I've missed or need to be aware of? Thanks.

 

Let me give you some advice that you don't want to hear.

Get rid of it. When you consider the wideband options available now, LC-1 widebands are nothing but trouble. especially the old 6 wire ones. I am saying this as someone who has owned one for years and have actually put together a clusterfuck of a writeup for it (search for threads I have started in this section). The heater control is crap--they are more prone to burning out sensors than competing products. They are sensitive to electrical noise. They are more work to install and set up correctly.

In 2005 or whenever it was that they came out, they were pretty good. Now you have more choices, including a few that use the newer Bosch LSU 4.9 sensor which doesn't require free air calibration.

 

Crap :P Thought it was a cheap and good setup; mind you, I did search before I purchased and almost everyone said it was a nice setup. That it eats a sensors quicker didn't really bother me as the car wont see more than maybe 2k miles a year max.. What do you recommend then?
