I have test pipes on my NA 07 and I got the light after only 200 miles but from what I hear the 07s are wideband. I dont know if thats true or not but if it is then it will be very interesting to see a fix on it. I even have the AAM test pipes with the 3.5 inch J-bend mod and it still didnt prevent the light.

BTW-----Thanks Shaif for the helpful info on the TN/Utec/NO2/11:1 CR install the other day

If it's the same as the '06 rev-up I'm working on than it is just the primary o2's that are wb's, the post cat's are still the conventional type.

I keep on getting P0172 CEL. At least it is rich and not lean. I am running 3" dual pipe straight from the turbos to the end of the car. I have non foulers in but I guess those arent working. Someone said that the 0172 is the first sensor and not second, sO I dont know.

sorry to bump. I just saw that a lot of people still look at this thread. I made a specific and more complete version of this o2 simulator for the 350z/g35. For those interested, here is the thread:
