This should help you out: https://www.evolutionm.net/forums/sh...anical+CEL+fix

 

Thanks! but i thought it should be a little machine.

 

Dont waste your money on a perrin "little machine" unit. Get the piece pictured above or pick one up from gruppe-s for $13 and you will never see that SES light again.

I have this done with my test pipe and havent seen a SES light since i installed it. And it only took $5 and 30min.

 

First off, most hfc's won't trip the cel.

Did you get the code pulled? If so what is it? Don't assume its your cat causing the cell until you pull the code and find out.

 

Some highflow cats don't clean the emmisions enough (my Perrin highflow trips the SES), the little cheater plug thing is the best way. After that you might as well get a test pipe.

 

As others have said, just do the anti-foulers. Mine took three months to throw a cel, but hasn't come back since. FYI its been a year and a half.

 

get a random tech hfc and you wont get a code

 

f the machine

+1 same here

 

When you get exhaust and a flash does this still occur or does the flash remove the 2nd o2 monitoring?

 

no, you still need it when u get a flash

 

Did you even check the code to see if it was the cat? For all you know it could be anything (even though the cat is highly likely to cause it given your situation.) Which HFC did you purchase?

 

I have used the "mechanical o2 fix" for about 2 1/2 years with my testpipe, Still no CEL
