I got a 88 crx hf with a 94 ex engine, so thats a d16a6 vtech i believe. I didnt do the swap, but thats the just of it.. I do know i dont have the ecu yet, and the tranny is still of the crx. So im wondering what ecu do i need, and would i NEED to swap trannies... or what? its a manual. Anyways can someone quickly explain to me whats the difference between the 0bd's and sensors and things like that....I know im a newb =/... alright thanks
