I'm running a vx swap and my afr gauge is reading all 4 cylinders. Its tapped into the lower side of the converter. So the 17:1 ratio is an average of those 4. The 3 that are running are still probably around 14.7 but the one that's pumping oxygen in with 0 hydrocarbon is changing the average to lean.
Remember I only tried this at idle because there are less variables, there's no change in tps, map, iat, egr. So you can expect the same result every time you do it. When ur driving everything changes and has a different fuel trim relating to what throttle position, load, coolant temp. Etc so its unpredictable.
I'm curious to see what happens when Stacy gets it going, who knows maybe itll work.
