Hey everyone! I just bought my first car; a beautiful 2000honda Civic ex coupe! I knew nothing about cars before I made the purchase, but since I've been trying to learn everything about her as I can. She has a Frankenstein motor, a zc block and a d16 vtec head. And as a result I've had trouble passing smog. My mechanic told me I have to get a new computer so that I can pass. But I am not sure what computer to get, because the engine is older than the car. I am hoping that some of yall have some insight as to what would the best for my setup. Thank you in advance.
