Your computer # 33920-56B30 indicates an 8V . #33920-56B51 should be for a
1994 16V motor w/auto. According to the #'s they will not interchange. The 56B30 was used up through 1994 so there is a good chance of finding one. The next question is why do you want to change ECU's? If yours is bad-no power to
injector-then it is very easy to repair it or there are several people on this board who will do it very reasonably. Just do a search on ECM Repairs. Good luck!
