Furthermore, the o2 is where it is to help get it heated and because it needs very precise o2 measurements. It's not going to work well in the normal o2 position on a header and it won't work well bunged up on the 3rd running 6 inches from the exhaust port, either, in my experience.
-I thought the VX O2 was a five wire and therefore heated?
also this will depend if you have a VX or HX. The HX searches for the "edge" via the knock sensor not the O2 reading.
