help please!!

My car is barley getting any spark. I think it may be the coil or the ecu. Under boost it runs better but after a minute the spark plugs are saturated with gas and it starts missing and poping. I have a 90 gsx and 91 gsx are the two ecu's interchangable? I think the two coils are different but can I swap ecu to see if that the problem

Can someone atleast tell me if the two computers are compatible?
