hi whats the difference between a usdm p28 and a jdm p08?

i know that p08 is for the jdm d15b vtec
the p28 is for the d16y vtec

i'm asking this cuz i have a chip for a p28 and i'm gonna use it for a p08, its for my boosted h22a type s civic, does it work?!

If its going to be chipped then itll be converted to 4wire o2 or just disable the o2 all together. Main thing is the o2, P08 is 1 wire and P28 is 4wire. Other then that i believe its the same maps, maybe a tad richer on the p08, but not enough to notice.
