i contacted comptech and they stated that there o2 terminator will not work with a MY06 due to the ecu being more sensitive. so any other ideas before i take the test pipe off?

 

Reinstalling the convertor sounds like the best repair for the CEL.

 

I have an '06 and I am running a megan test pipe with the O2 sim. I followed the DIY for the O2 with no CEL. Post some pics.

 

im glad i found this...

I threw a CEL with my Megan TP and 2 non foulers... oddly it only stayed on for about a week and went away.. then i put it back to stock and it stayed off

Now i have my Berk TP with built in 02 sim, and ive got a CEL.. imma wait another week and see if it goes away.. if not i may just live with it, or maybe add a fouler

 

i have a T1R test pipe with their 02 Sim and i have never had an issue with CEL's ever... over 3000 miles.
