^^^So you are saying if unplug the MAF, install the SEGR, then I can uninstall the egr valve so it obviously will be unplugged, I may have a chance that no code will pop up?

By the end of today, the whole thing will be off the jeep for good!

There are a couple ways to turn the EGR off. There are a few reasons we shouldn't talk about who can do it. I don't want to get someone in trouble. It can be done though. Quite a few people have done it. The SEGR can shut it off and the other is a tune. That tune was done to prove that you can block the EGR off and not get a CEL. The tune allows you block off the EGR if the owner chooses to do that. You may get a CEL if you completely remove the EGR because of open circuits, I never tried that. If the EGR pipe is blocked off, it isn't going to get any exhaust anyway. The path of least resistance thing!

I believe the EGR can be gone, but I haven't done that - Tim kept the Flow Control Valve to help on shutdown.

I don't know anyone who's physically removed the EGR - most just block it off -
and Export models appear to not have problems with the EGR blocked off and the FCV butterfly gone -
US models get a Check Engine Light

Export models are using Euro 4 EC units and are not hunting for emission fluctuations as much as the US models supposedly not causing codes to be thrown if the EGR is blocked off. That's what i was told by the service manager at the dealer today.

Who can I contact for "performance" tuning?

We tune focus models all the time to turn the egr and even one of the o2 sensors (1 of 3) in order for the comp not to throw a cel. Who can I contact for "performance" tuning?

Me.

Oops. Edit. I am in the market for such a tune, I am not offering one.

You have a PM my friend

For just performance add on - you can try the Edge, Predator, Dr Performance type boxes
but to retune the ECU you're looking at Inmotion or Kermatdi
Inmotion says they can't turn off the EGR, Kerma doesn't mention Jeep
but if you talk to them you might get different answers for offroad use

as always - these EGR mods are for offroad use only - we wouldn't want to modify a Federally mandated system for use on the roads

I will talk to both companys on monday.

Another thought I had is to just dump the egr exhaust back into the exhaust system. Has anyone tried this? This way, I can still use my maf and not need the SEGR and then also, the EGR is happy and my intake is happy.

That would be the right answer! That is what everyone does I believe.

haha, how come no one mentioned it?

What happens to the exhaust gasses if you block the EGR off, they have to go somewhere dont they :wink:

HugeKJ05 · **Posted:** Sat Dec 13, 2008 6:23 pm

Yes, but this way I dont need to buy an SEGR. I have plenty of tubing here to weld up a dump tube for the egr. Kinda the same I guess

ATXKJ · **Posted:** Sun Dec 14, 2008 10:12 am

There is a feedback loop - but I don't remember where the sensors are.
I think the MAF - incoming air, EGR gave returned air and FCV was choking the intake so that it would pull in the exhaust
and if the computer didn't see the proper response - it'd still give a CEL.

it was in the original thread that I can't find now (and it was about 40+ pages so I'm not sure I could find the info even if I found the thread)

someone had mentioned routing intake air to the EGR - clean air - but still fools the sensors -
but he never posted pictures and he went away.

Won't work. The ECU expects the MAF to change when the EGR is cycled. If the airflow doesn't change in response to an EGR open/close it'll throw a code.

Hi, I am new to the forum and have had my 05 CRD for a few months now. When I got it I checked it over well and didn't see any leaks at all. I do brake and chassis testing for the big three for a living and I consider my self somewhat capable of working on my own stuff. Anyway yesterday I had the Lib on the hoist to change the tires and melt all the caked on snow off and I noticed some oil wetness on a pipe on the turbo side of the car. I followed the pipe up and I notice that the bottom of the turbo is wet witl oil. My first thought was "great my turbo blew a seal" but the more I read up on it and after seeing the pictures that were posted on the thread I am thinking (hopeing) that it could be built up oil in the cold boost tube. What do you guys think?
Sorry, I didn't plan on rambling off so much, I guess I should have started a new post!

Oh Yea, this is a great form!!

Howdy - welcome to LOST

If you're 05 is stock then - your CAC hoses are coated with oil - and may be dripping.
my stock ones blew about 30k miles
They were covered under warranty - next ones will be Samco
(unless HugeKJ05 get's his welded versions going those look nice)

I think a couple of folks have had Turbos replaced under warranty -
but the way the Dealers are - I'd expect 1/2 of those to be without cause

you can pull the CAC hose ends and look - get an idea of how bad they are.
if they are bad enough to be dripping oil - expect that you'll need to replace them fairly soon.

check over in CRD tech for EHM or Provent. and the ORM mod is helpful too.
