I install my zzp header and downpipe combo last week and just threw the code last night (CEL). A few questions. Doesthis effect my preformance? should i talk it to chev to check the code and can they fix it or should i go somewhere else to do it. I dont want to tune my car, I only want to get rid of the CEL

 

To get rid of the CEL you will probably need to tune the car by someone with HP Tuners.

It will not effect your performance though with it on.

 

Did you get a high flow cat or no cat?

Even with high flow cat you'll get the cel from time to time. Best bet is to get a tuner to clear it out or get the ark cel eliminator.

 

I have the high flow cat..... GM cant get rid of it right ? and i dont not want to tune my car to get rid of it

 

No, GM cant get rid of it. Basically leave it the way it is of get a tune for it.

 

Gm will only be able to clear the code and by going to them with this problem you run the risk of them voiding your warranty. You have a few options

1.) Everytime the CEL comes up, unplug your car battery for 5 minutes replug and start the car and let it idle for 3 minutes then drive. (You will be doing this often)

2.) Get a tuner to turn the code off in your pcm (this is the best and permantent fix)

3.) Get the Ark Cel Eliminator (mixed results I've never used it)

 

Does it makes sense that the CEl came on over a week later or could it be something else? and is it possible for an hpt to erase the code and juse leave my tune

 

Mine came on the day after, went away the next and hasn't come back.

Guess my prayers were answered.

 

With a high flow cat under certain conditions it may pop up.
HP Tuners like my self can remove the code and leave your tune alone. If you lived closer and if your an 06 SS S/C I'd be able to do it for say 10 bucks.

But thats because I have all 06 SS S/C's unlocked. Other wise its a 100 buck to unlock your car to be tuned. So again if your going to pay why not go ahead and get tuned?

 

I dont want to tune it cause i want to keep GM tune! keeping the warenty

 

lol james its not all 06's SS/SC......

 

I going to go to a local shop and get it scanned for the codes. please check back as i will post them

 

Let me explain in my case I have all 06 Cobalt SS S/C's unlocked. So I can tune an 06 Cobalt SS S/C with out spending credits.

As for the problem the OP has stated I was not implying that it's limied to only 06 Balts as any of the 3 year (05,06,07) will have this problem. I was just saying if he was an 06 I could take the cel off permanteley for 10 bucks.

You ever get your car fixed Sean?

 

nope still locked tune, and i think i fried the cat hehe

 

ok well i cant do it till tomorrow mornin' but you guys that tune cars... It IS possible to just delete that code for the CEL without tunning, and will GM know that it has been done?

 

So i just had my car scanned and there was 2 codes, both having to do with the downpipe!!! so yeh i guese i have to look for a tuner to delete these now ???
