DV,
I sent the ECU off to be reprogrammed to require 2 sensors instead of 4. I'm not using CR pipes, I had some custom pipes made. The sensors are mounted on the flange that attaches to the bottom of the headers. I was directed this way from Emerson. This is what they do with all their 4.6 fuel injected setups. We should know how well it works in a week or two (gocart phase).
