Ok so I wired up an safc neo on my 91ls 400 1uzfe in my 95 nissan 240sx. Everything seems to work fine except that when I adjust fuel trims it seems to only effect my passenger side bank on my dual band wide band gauge. Also the car sounds like it has a miss on the driver side and reads just a bit rich at idle. I wired it up with the Karman maf sensor due to that is the one I have. Im lost as to why its only adjusting the fuel trims on one side. What did I do wrong? Thanks for any help in advance.
