As you know i fought this cel for two weeks with no luck. Finally i got a combo that works. 3 Spark plug anti foulers (the long ones) with the one that the o2 goes into drilled out to 7/16 only about 5/8 of the way down. Just enough that the o2 fits in there. Been about 2 weeks atleast 50 cycles and about 600 miles and no cel. The reason its such a PITA to get no cel is the ecu is more sensitive to make better use of the dbw system.

 

i have an 06 with the T1R test pipe and their 02 simulator and i havent had a CEL ever... running good for 3000 miles.

 

Berk Tech test pipe just becaem available and as I understand includes th CEL fix (or negates it).

Perhaps others have had experience with it?!~

i have a T1R 63mm and a T1R test pipe and i've had cel since i first put it on

 

did you use their 02 simulator?

 

yup

 

anybody else have luck with this? i purchased the Berks TP and i keep triggering a CEL. i read the design between them are different also.
