Ok, so I installed my Perrin down pipe and cat delete today with the O2 Simulator. Even with this CEL fix, I am still getting the CEL light. I have a EVO IX MR. The light on the simulator is flashing (which I think means the + and - are in there right. I had the simulator spliced in on the white wire and then the blue one (even though the blue was supposed to be ground, I found that the black one was.) If anyone has had this problem or anyone has any suggestions, please let me know. Thank you in advance for anyones advice!

 

hmm.... i used the same with no prob... sure its the o2?

 

Did you use it on the EVO IX? I am not sure it is the O2, but what else could it be because there was no problem until I just installed this...

 

yea, mines a 8..... if i remember correctly, blinkin light means it right.

 

THat is what I thought... Like I said though, the wiring seems to be different because the black wire seemed to be my ground and not the blue one... (That is what I found when I tested it with a test light).

 

on mine, the black was on the cel fix and was to be chassis grounded. did you ground thatone?

 

Has anyone installed one of these (especially the Perrin one) on a EVO IX? If so, can you tell me how you wired it? The wiring on the IX seems to be different than the VIII and I am having trouble figuring it out from the instructions. Can anyone please help? Thanks in advance!

 

same this happened to me with my 8 light was flashing means working but the cel was on so i replaced the 02 sensor no more cel light...

 

I grounded it to a wire in the O2 sensor...

 

This is a brand new EVO IX though with 2200 miles. The O2 sensor should not need replacing.

 

just do the easy mechanical fix with a $3 spark plug fouler

 

yeah do the spark plug anti foulers or have a extension made, i heard that 02 sim dont work on ix's

So this anti-fouler will get rid of the CEL? How does it work? How much are they?

 

Does anyone know?
