I think I figured out how to set this thing up.
This is what I did.
Pulled WB02 out.
Turned key on till sensor was hot.
Hit ground calibration button. Key off.
Put WB02 back into exhaust. (Sensor is hot!)
My LC-1 gets its ground from a wire leading back to the passenger head front bolt. Power comes from the fuse box.
Opened LMProgrammer and set it to 2.5 volts/2.5 volts and 10/18 AFR. 1/6 of a second. Program. Close.
Now since its 0-5 volts, 10-18 afr, then at 2.5 volts it should be telling HPT its putting out a 14.0 afr. I opened the user configuration for the LC-1 while I wasn't scanning. You can't seem to open it while your scanning, but if you leave it open, you can change the equation in realtime.
So the equation has:
Volts/.625 + some #. Mine uses 10.07. Leave this window open, then click on the "VE - Wideband O2, AFR" histogram. Configure it to show 3 decimal places. Start the scanner. If your equation is correct, you should see the 1 cell populating with numbers near 14.000. The longer you let it run the more accurate since it is averaging. Now, at this point you could change the "+" value in the other window. In my example, if you changed the 10.07 to 8.00, you would immediately see the AFR drop. Stop the scanner and clear the histogram. Lets say you were pretty close to 14.000. Try 10.06 or 10.08 depending. Start the scanner again. This is all while you have the User config LC-1 still open mind you. It should now start showing you the average afr again and it should be closer or farther away. Each time, make a change, stop scanner, and restart it to see a new average. I got mine within a hunderedth or so. When you set the histogram back to show 1 decimal place, it should read rock steady at 14.0. Go back into LMProgrammer and set it to 0-5v, 10-18 afr.
Now this is linear and will only be really accurate near 14.0 I think. The only way to make it really accurate would be to divide the 5 volts up into the 60? points that the list option will let you do and figure out the values at each point so it can develop a curve. That would be really time consuming!
