Ah right then. You need to get a WB kit. Search the web, there is a guy that makes the kits, he's in Canberra. They are around $500. They output a 3v signal which can only be used by a proper wb detector. You can't use the autometer guages, they're for the stoich(1v) af sensors only.
Where did you get the wideband from(Honda)? How much did it cost?
Just cause its 4 wire doesn't mean its wideband by the way.
