I have a 1993 honda prelude si w/ a h22a in it among other things. I have the jdm type S header that has an O2 plug on the 1 pipe section, before the flexpipe and cat. I heard there is a product that screws in where the o2 plug goes and sends the right fuel/air, no matter what the real reading would be with the cat removed. Anyone have more info??? Or possibly another way to bypass the CEL?
Thanx
