I'm making a ram air induction system for my 91 z28, by conecting the fog light air ducts to the air filter housing. Does anyone know if the ECM might have a problem with this? If anyone has done this and has any suggestions, I would like to hear them. Thanks!

 

That should have no effect on the ECM's programming. Even if there would be a slight amount of extra air, the computer's feedback system (closed loop) would correct itself under most driving conditions (provided your O2 sensor is functioning).
