Did you ever get the problem with your B2S1 O2 reading constant .447 with the LC-1? I saw your thread on innovates site with no real answer. I'm having the same problem with mine wired using Joecars wiring.
Thanks

Measure the voltage across the LC-1 red/blue wires, must see better than 12V.
Try powering the LC-1 directly from the battery (with an inline fuse on the red wire) temporarily, and see if there's any difference.
Did you ever [accidentally] short the yellow or brown wires to anything...?
No answer...gave up and bought LM1. It's possible Joe's right on this one though. I tapped into the stock NBO2 heater switched 12v and heater ground. You'd think it'd be more than 12v, but I never checked that.

Here is an idea for power for widebands...use a cig adapter plastic thingy, mod it to remove the grnd and have the wb grnd setup to some other grnding pt (leads set up to ground from the wb) to avoid the backfeeding condition upon starting via the starter that has fried countless WBs

I'll check voltage today after work.
Have you tried monitoring the LC-1s serial output via logworks? If you can get a decent reading with LW then that would probably confirm the death of your analog o/p.

Yes, logworks matches EFILive actual AFR after modification to the gen.txt file by adding .03. I have hooked NB hooked to analog 1 and EFILive to analog 2. Analog 2 reads fine through live.
