Link Noob needing help.

Everything seemed to be well on my mostly stock car. I swapped out the known good NBO2 for a LC2, and the thing now wont get into closed loop. It does generally start at .2V, and then moves to .8V and stays there. The gauge for the wb works, I have the simulation in link clicked and the Front O2 identified. If someone could take a look, I'd appreciate it.

I turned off the NBO2 Sim in Link and ran the Brown wire from the LC2 as my signal to pin 4 of the ECU. If I backprobe the connector, I see voltage oscillating. But Link doesn't show any oscillation, it just sits flat at .04V. WB Gauge seems to be reporting stoch (14.6-14.8). I'm running out of ideas.

I reconnected the yellow wire from the module to pin 4. If I disable nbo2 sim and then renable it, ECMLink shows closed loop, but voltage is fixed. The gauge shows fluctuating voltage, but linked is locked at .08v.

She aint happy. WBFactor is -62%, AFR is fixed at 8.0

Log is attached. I CLEARLY have no idea what I'm doing. Please help.

turns out the issue was the female pin in the ecu connector not connecting to male pin. please dm me if you know where to find them.

Try Sheridan engineering for pins. Brad is a good guy.
