LC-1's simulated narrow band

[Gelf VXR]

On several occasions the PCM's throwing fault codes saying voltage to high and dropping it to what i think is limp home mode? Stalling and difficultly getting the revs up. Swithching ignition off and back on will cure the problem.

I was wondering about the NB program settings.

I have 2 wide bands which the indicator lights are both showing showing normal status.

Anyone had simalar experience?

I presume you are feeding the NB simulation into the PCM.

When you log the narrow band what is the peak voltage?
Maybe reconfigure the LC-1 to keep it below 0.9V (900mV).

Yes i am on both banks, i'll try that thanks

The sensors just needed to be air calibrated
