there has been some modification with the newer models ecu it's a little more sensitive.

please post your results

Just an FYI, the 02 spacer trick is to erradicate code P0420 only (cat efficiency) for those wanting to run a test pipe, or for those who's cat-converter has worn out and are tired of the CEL

It has worked great for me on 00-05, but the 06-07 is definitely tough. It is very sensitive, seems like those who've had success are getting the luck of the draw, or very specific parts.

I have just tried:

-first spacer screwed into test pipe, untouched
-second spacer drilled barely bigger than the 02 for a close seal

the CEL still comes back.

At this point I am going to weld the hole shut in the first spacer, and re-drill it out about 1/8" maybe smaller.

I'll let you know how it goes....

 

 

My $$$$ is on no easy mechanical simulator for the DBW cars. The Catalyst and 02 sensor monitors are more complex than previous cars.

I've got a guy at work with a Berk TP and a 07 complete with CEL.

 

TBA....

 

Would this not be the same as the Berk? Jake, (Dark Sub Rosa) did this on his MY05 and got the CEL.......

 

Prove me wrong, please do

I look forward to you figuring out how it can be done.

 

Subscribed... hope someone figures it out.

 

Ahh the car manufactures have finally figured out our trick
