dpfi ecu interchangeable question

ok so my 91 civic had its ecu fry and iwas wondering if i could put a ecu from a 88-89 in my ride or do i gotta stick with 90-91 as well if the crx ecus will fit in my htach

88-91 will work fine. Just make sure its for the tranny you have. If you have a 5spd then you need an ECU from a 5spd car, Civic or CRX, they are all the same.
