Diagnostic Code 0471 After WOT with GTHaus open

Over the last couple days I have had My SRT out beating on X5's, and X6's. On two particular instances (One last week, and One last night) after opening the valves on my GTHaus, and going WOT a few times on the highway I got the malfunction light on the dash, and am seeing the diag code of 0471. It went away after about a day of off and on and closing the valves the first time, and the second time started last night, and still hasn't gone away (only restarted once to come to work this AM). My remote start does not work while the code is present either. I did some research on here, and apparently some other have experienced this even with the stock exhaust. So really I am just wondering if it is simply the change in back pressure that is causing this? is this something that is going to happen when i have the valves open? Everytime i gun it with open mode? Is there a trick to avoid it? Is it causing any other issues? Any other GTHaus guys experiencing this?

thanks

Re: Diagnostic Code 0471 After WOT with GTHaus open

it is the change in back pressure and was experienced by some of the first 2012 guys who added exhausts that kept and removed the oem flaps. Not much has been reported since then. This is the first in awhile here.

Re: Diagnostic Code 0471 After WOT with GTHaus open

Crazy. I've had my GTHaus for almost a year and the exact same thing happened to me Friday night. We had a bunch of cars together for a spirited cruise on some Mexico freeways and at the end of the night the Check Engine Light came on with the exact same code. I closed the valves and it went away a day later. Funny thing is I've done a lot more aggressive runs with the valves open all night and no issues.

Now that the 2015s don't have valves I'm wondering if we can get an OEM flash to eliminate this problem.

I've got a Borla type S. I ran all day at the track with no issues and I was running hard.

Re: Diagnostic Code 0471 After WOT with GTHaus open

The weird thing is like AKON said I too have had the GTHaus for a long time. Put it on in may, and RARELY close the valves. This is the first times it happened, but now its happened twice in 5 days. Sucks that until it clears my remote start won't work, and its starting to get cold. Seems like the fix for me is to close the valves, and in about a day it just clears. Anyone know of a way to clear the codes on our Jeep without a tuner? I just hit the 4K mark and have been driving her a little harder lately, thought it might have been related to that, but maybe its the back pressure / temp being lower.

Re: Diagnostic Code 0471 After WOT with GTHaus open

This can happen I think TOM figured it out a while back

In Open Mode if he hammered on it it would throw a code then he would go in for the night and come out to no code he finally figured out it was in fact whenever he got on it in OPEN mode only.

I'm sure it has something to do with the adaptive's and very few have the issues honestly less than 1% but it can happen. This is only the 2nd and I think someone else said it happened to them here too so 3rd time I've heard this.

I wouldn't worry too much about it even tho it may be anoying their will be a tuning fix I'm sure at some point.

Same this happened back in 2006-08 before the tuning was really dialed in and they have gotten ever more complex with the computers so it's no suporise to me their is still no guaranteed fix.

Not sure Tom's still dos this may be he can chime in here.

Oh It's loss of Back pressure I'm sure The Gthaus Really flows in Open Mode I'm sure a lot more than anything else on the market!!

Re: Diagnostic Code 0471 After WOT with GTHaus open

Chad,

Thanks for chiming in. I'm pretty sure its just a nuisance thing. Although it sucks that my remote start didn't work in the AM after I still think it was well worth it seeing the face on the X5M, and X6 drivers face as i stomped on it and passed them with the valves open. Wish i could describe in words the feeling and emotion i could see on their face. It was pretty awesome!! LOL.
