LC-1 Install questions
 

Has anybody used the stock O2 sensor location, with the stock ECU, utilizing the LC-1 analog 1 output? and if so did you have to reprogram the analog 1 output?

Someone correct me if I'm wrong but i don't think the stock ecu will read the wide band. I believe most people just use a second bung and leave the stock one in.

The LC-1 has a narrowband output (analog 1). analog 2 is the wideband output. Hence the original question.

I have been running an LC-1 and MS-Parrallel for about 2.5 years. When I first installed my LC-1 it went in the stock o2 bung and I wired the narrow band output to the stock ecu and it has never given me problem. Still wired up that way now.

Wired mine like that 2 weeks ago. Still running on the stock ecu... Runs fine. I tweaked the settings on analog one a little bit to stabilize the AFR, it was swinging quite a bit when I first put it in there. 2 8 Ohm resistors wired in series to fake out the O2 heater circuit. No CEL, no pending codes.
