Longtubes and O.R. X stupidity.

[DDTCM]

Fuck me....I hate to post this question but Ive not found many answers using the search feature.

Im about to send the car (2011 gt) to the shop for a LT,off road X install. I have a Boss intake and tune that i will throw on when I get home so the question is....

The trip home is about a 30 min drive. Will the car be good on that short trip home? Im thinking it will probably throw a code and if so that code will have to be cleared before intake and tune install,correct?


Flame on brothers.

i wouldnt worry too much if only a 30 minute drive

I already have the tune for the whole shabang. Just hoping it will be ok to drive home until I throw on the intake and new tune.


James,I failed to catch a video of the dog sliding down and spearing him in the gut at the bottom of the slide. Now that shit was funny.

My wife is gonna steal your dog. lol. I think it should be fine. It will just throw a code for the 02's, who knows they might be turned off already.

It will throw a code and add more fuel, but you should be fine if its just a 30 min drive.

keoni, I ask this question because I don't know, not because I'm trying to argue lol

If there are no cats then wouldn't the downstream o2's read rich and cut fuel?

Only thing I would really worry about is fouling out a spark plug, but I don't believe there would be any issues for 30 mins of driving... just be easy on her, which I know will be hard with a new exhaust lol

I've read/been told by multiple tuners that you don't need another tune for LTs. The widebands will adjust for them on their own. The only code that you should get is the rear O2s telling the PCM that the cats aren't doing their job. Call your tuner to verify.

Can I clear that code with my SCT or will it fix itself once I return it to stock before throwing in the new tune?

 

[JEWC_Motorsports]

You can clear it.

 

[DDTCM]

Good deal.

That's what I originally assumed as well, but I read somewhere (can't recall) that stated the opposite. Of course, I could be completely wrong (which isn't uncommon, lol). I can't remember what reasoning was used for the car adding fuel, but now I'm interested again. I'll try and dig up where I read that...

 

[BAKnBLK2010]

The car adds fuel to cool the cats when they reach a certain temp. It is a very small amount and would no way foul any spark plugs. You won't have to clear the code before loading the new tune either. You will be fine driving it home and probably won't get the cell if it's only a 30 minute drive as the car has to go thru 2 drive cycles before it will throw the code for no rear 02's.

 

[GrabberBlue5.0]

but if the cats are too hot wouldn't the car be creating excess CO2 from the burning even more fuel? and with that said, o2s would read excess gasoline meaning that (assuming there were cats) they are still too cool to burn off the fuel. I don't know it all by any means but just trying to get the right answer.

 

[keoni1984]

That's what it was. Thanks BAKnBLK for clarifying.

 

[DDTCM]

Thanks for all the help y'all.

 

[keoni1984]

When are they doing the install?

 

[bmaxwell]

Baknblak is right. Grabberblue stop arguing! haha jk

 

[TexasBlownV8]

Dan, you'll be fine driving it like that. The pcm does not read 'cat temp', just 'efficiency'. The current tune would make minor adjustments for and rich/lean adjustments under part throttle, and you might get 'o2 sensor slow response' codes after the install, all corrected in the tune.

How are you going the handle the 'o/r aspect'? (you can pm or call me here or on cts to keep it private).

Otherwise, ITS ABOUT F***ING TIME you make some nice mods to that car!!!

I'm waiting on the O2 extensions to come in later this week then I will take it to the shop.


Mike,I've been sitting on these LTs and mid pipe for a couple months now. Then I came across that Boss intake for a great price and decided to do everything at once. The canned tune is gonna be temporary until I get a real dyno tune to take advantage of everything. My tags are up this month so I will pick those up before the install and have a year to worry about inspection.
