What CEL codes are you getting?

Have you found a non-ecu related method to prevent CEL?

TIA

 

Cat deficency. I just use my scan tool to clear it.

 

Do you know the exact code. i.e. p0136.....

I clear it, and within 15-45 mins, it comes back...

 

I just saw O2 extenders on FVD's website. Maybe worth a shot?

All they do is extend the O2 sensor out of the exhaust path. There are also "black boxes" that might trick the ECU.

 

I'm using a form of the O2 extenders, with no luck.

I tried to locate the FVD o2 extender on their site, with no luck.

 

Can't your turner tune around it? I was talking about doing a cat delete and cutout custom fab job on the stock exhaust and Tony at EPL told me he would code around the CEL.

 

For off road purposes only of course.

 

Yeah, what he said.
I'm going to have to draft you up a disclaimer for your signature file.

 

Off road, well of course. My car is NEVER driven on the road, cause that would be a big no-no.

 

My tuner will not program around it...

So anyone got the CEL codes?

 

FVD will,Thats why I went with them for this. I guess you can use a scan tool , or even a brokway engineering 920 to do this.

*** For off road only of course ***

 

i have a OBDII reset tool, but the light comes on way too often....

also i want to double check that the codes im throwing are from the hollow cats, and not blown o2 sensors....

 

Right on there front page after you chose 996TT from the drop down menu.

Although I have never run hollow cats on Porsche's, I have used a resistor fix on many import tuner cars without cats to eliminate the CEL.

Here is a link to one for a Subaru STi. Essentially it 'fools' the ECU by changing the feedback voltage from the O2 sensors. I am not sure of the correct resistance value that would be needed for the Porsche system and it would also need to be spliced in.

Has anyone tried to just "hang" the second o2 sensor outside the exhaust and plug the hole?
I really can't believe someone has not come up with a 'offroad" kit to plug into the harness to take care of this issue.
