Well I was reading about reprogramming ECU'S on www.jdmhondaparts.com, and it said he wouldn't guarantee that people would pass their emissions test. I'm looking to get a b18c1 swap soon, only thing holding me back is getting time off of work and more info I need that I dont have. Now I'm worried about not passing a smog test, I don't want to have an illegal car. So if I just got a b18c1 (GSR) swap with just a GSR ECU will I be okay??? I live in california if that matters by the way, Thanks
