i just installed a greddy ti c turbo back on my 2011 x the greddy kit came with an extender and the shop that installed it installed the extender for the o2 the car ran all last night with no cel but this morning on the way to work it came on. i also bought a vibrant o2 extender but didnt install it because greddy sent one. do you think vibrant will be better? i am eventually going to get tuned but i want to get a few more parts before then but in the mean time i dont want that cel light showing . Is it bad to drive the car with the cel? Is there a way to shut the cel off without having the car tuned? I did search but couldnt find anything specific to what i was asking.

I also had an evo ix and used a defouler but it worked is the evo x more sensitive?

thanks in advance!!

 

If the turboback setup came with that defouler, it is probably designed to work fine with it. I know it could be coincidental, but have you had to code read yet to determine if it is p0420 (or whatever code people get with the exhaust)? You can go to any automotive store and buy a code reader which can tell you what the code is AND clear it so that the light goes off.
I would recommend you get the code read first to make sure thats your problem, then try the other defouler to see if it keeps the CEL off.
There will be no issues driving the car with the CEL on, it simply indicates that the issue was present.

 

ok ill have it checked after work today to see what the cel is for. i will check back afterwards.

 

ok had the cel checked it was indeed for the o2 sensor so im going to try the vibrant defouler to see if that works better

 

it it's turbo-back, i think there are 2 O2 sensors

you should probably just buy a Cobb AP

 

Defoulers/extenders generally don't work on the X, you'll need to get it disabled within the ECU (Cobb Accessport or ECUFlash).

 

pull battery then wait 5-10 mins and put back on! Or go to autozone and have them clear it...

 

i have the same issue dude. ,but my light comes back i input my defouler in the 2nd hole in my test pipe and cover the other one. but this light is annoying is it safe to drive with that light on ?> i mean i did on my SI till i figure this defouler trick but never on a turbo car...
