Sup guys I got a question for you I used to have a b18b swapped into my civic, when I had that engine in my car I could always check to see wat check light I'm throwing by pluggin in the computer. Well after putting my b18c when I tried to use the computer it keeps saying it not getting a signal from the ecu. So I was wondering could it be the wiring or maybe the pincut to my ecu isn't in the right spot? If you all could help me out it would be great.
