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?

 

no one has ever replied to this look at the date posted!!!!

 

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.

 

and then you'd want to drive around normally so it can relearn the fuel/timing curves.
