Ok I have a 92 civic vx that has a d15 in it that’s blown up I have a b20 that I am swapping into it and I don’t really know what to do about the ecu. Can I use the one in the car or do I need a new one and if I got one that matched the b20 would I have to do anything to get it to work with everything else? I’m pretty new to engine swaps please help 🙏

 

No you can't. You have WEEKS of reading to do before you even ask another question or you can pay someone who knows what they're doing.
