i have the dx model with the zc swap....curently i have the 90-91 si ecu in it,i have the 86-89 integra ecu..should i change it? if so do i need to unhook the battery....


is this something i can just change and use or do i need to change anything else?

no you donr have to unhook the battery, and its always best to use the ecu that for the motor

well i'm told both ecus are the right one...its just that the integra one offers a higher rpm to 7500rpm and uses more fuel,better performance....the one in there now is better on gas and rpm is around 7000....
