new megan racing header
 

i just got my new megan racing header put it and it sounds great but after about 2 days the cel light popped up and its ____ing me off because is it aight to drive wit it on? What is the antifouler that everyone is talking about? how am i going to get the cel light off

Search, there are billions of threads on "antifouler mod"

dont go antifouler try the zpi 02 simulator first. The antifouler only covers up the problem where as the 02 simulator fixes it and gives you the gas mileage back. But I have heard that the 02 simulator doesn't always work. IMHO I would try the 02 simulator first because you can fix the root of the problem if not....cover it up with the antifouler.

The simulater doesn't change anything regarding mileage.... it essentially does the same thing and the antifouler.... but through electronics, but adjusting the signal...

The antifouler does the same thing, but physically, by pulling the O2 sensor out a bit, it reduces the what the sensor recieves, thus adjusting the signal...

The secondary 02 does not affect mileage or engine settings
(it's not even wideband), it is a pure emissions/idiot light used sensor...

geez wassup with these header mods and foul lights

hehe was going off of what the 02 simulator description off of zpi's site.....but since I've did the 02 simulator it seems that I have the same gas mileage that I used to before the intake/header combo perhaps its just my imagination hehe

I have the Megan header and ZPI s-pipe with the antifouler and no CEL, I have well over 10K miles with these things on and no problems.

No CEL w/ my AW header, CC s-pipe and anti fouler 2-3000 miles on the setup.

The antifouler mod works when done right, no matter what kind of header it is and its the cheapest fix to the CEl problem.
