I have swap a 97 JDM Type R swapped into my 2000 Civic Si (Canadian Version). I keep getting Code 20 cel. I checked the under hood fuse box, and there is no ELD sensor or fuse. How can I make this go away? Does it effect performance in any way? Car runs well and pulls strong in every gear. I tried swapping a p-28 chipped computer with skunk2 conversion harness, and still got the code 20.
I've been running the car like this for close to 8 months, but would like to get this resolved.

Thanks in advance
