Single channel O2

Different brands of wide bands often don't read the same. Different engine combos don't want the same air/fuel ratio. My 358" SS engine with VP C11 likes 12.6 to 12.8, my old 383" 14.25-1 compression bracket engine on VP C12 likes 13.3-1 to 13.4-1, all according to my FAST XFI, and my old DynoJet dyno wire band agreed.

The LM1, LM2, LC1 stuff that came through my shop (kids installed them in their cars) were all over the place, some showed richer than mine, some leaner.

BigStuff3 systems agreed with my dyno wide band also. You just need to know what your car likes according to your wide band.

Like Adger said, it's just data. Only a reference.
