i have a 91 crx dx w/ a turbo 88 crx si motor. i recently hooked up an safc. i dont know if this is right, but when i put the afc % into the negative, it richens it up. when i put it in the possitive, it leans it out. is this hooked up wrong? it works fine, but i just thought it was a bit weird. i am running the hack also. every thread i see on the hack, people put their correction % into the negative. my car doesnt run when its like that..only when its in the positive. help me
