I have a b16 in a crx with what looks like only 1 map sensor on the firewall should there be 2, i heard that there should be 2 but i am not sure, the reason i am asking is that i am runing super rich. I have no CEL's if that helps

 

You can use the map that you have, I'm running the same one. Obviously your vaccums are right since there are no cels, but B16's do run a little rich. I dont think you have anything to worry about.
