Usdm/jdm Ecu

will a 87-88 usdm ecu work with a jdm 87-88 13b motor? if so, what will be the differences in running a jdm ecu with jdm motor and usdm ecu with jdm motor?

yes,i think i was told that the jdm ecu has a slightly more aggressive fuel map, or at least for the turbo

we were looking at a bunch of rotor housings and the jdm series 4 has the leading plugs a tad lower, so the timing is gonna be a tad different, between usa and jdm.
