The total range of adjustment is normally 50 degrees, for mine 40 degrees from a mechanical stop I added. It can't be negative, and I don't have an exhaust cam phaser. I'm unsure if 0 degrees on my engine corresponds to 0 on yours.
At 0 degrees cam advance I found my fueling is somewhat erratic, in a way it isn't with 10 degrees advance. It seems to swing +/-4% without much rhyme or reason (in the same cells) whereas +10 is generally within 1%.
