computer changing ai/ratio b/c of cold air intake
Just wondering if anyone knows if by putting on a true cold air intake on a 90 civic dx 1.5 if the computer will learn to change the air/fuel ratio? I'm chaning out the O2 sensor today and am wondering if the computer will compesate for the cold air intake. Should I disconnect the battery for about 15-20 so the computer will relearn everything?

With something minor the computer will learn, with a turbo/supercharger its too much for the stock computer alone so thats when you need a new ecu or piggyback. Its also a good idea to disconnect your battery after all performance mods, let it idle for about 10 minutes.
