IIRC it's one of the analogue outputs that need to be programmed as 0-1v narrowband.

how does setting stoich, which is like .45v on a narrow, at 1v on a 0-1v scale, work?

lc-1 manual claims their Analog Out 1 is already programmed from the factory to narrow band specs. It shows 1.100Volt at Lambda: 0.958 and 0.103 Volt at Lambda: 1.022
