last feb i did a b18 c swap into my 92 civic si hb. everything has been running just fine until a month ago, when my car just died. ive found that the fuse under the hood for the ecu is blowing. its a 15a and the car idles just fine but as soon as i start to drive the car it blows again. the ecu came with the engine any help would be welcomed

 

You've got a short somewhere. Get a wiring diagram and start checking circuits.
