Probably just the emmissions stuff. Your car actually might run worse with the Jspec ECU since the cars there don't have any emmissions equipment.

i'm not sure but i think if u remove ur emisions equipment it should make a difference. i have a primera motor on my 92 se-r and i removed all the emissions stuff and the cars runs just fine with the stock ecu but i think it would run even better if u use a j-spec ecu. if u can let me know wear 2 get 1 i'd like 2 try 1
