I think a narrow band will only read correct at 13.7 and will not show correct on either side it's only for OEM computers to keep the mixture and the 13.7 a/f ratio nothing more.
I think last time I purchased wide band sensors they were like 75.00 each, may be wrong. I know they are very expensive.
