ANyone done the EGR delete on the MM? Pro's and cons?

[juno]

Just curious if anyone has done the delete and if it helped or hurt the performance or tuneability.

[KillJoy]

I believe at least one here has done it.


I think he said the only issue was that is took a little bit longer to get it warmed up and running well in cold weather.

I've heard the talk of no benefit, but, why did Zack do it? Why did Jerry Barnes do it?

[Fast4Door]

I got rid of mine when I installed the blower. My main reasons:

1. The ESM (EGR System Module) is a high warranty item and expensive to replace out of warranty.

2. With a Trilogy, the unit is placed right over the trans dipstick, making it very tough to check trans fluid (the ESM gets HOT).

3. The EGR system is there to reduce NOx emissions and provide a fuel economy benefit. I haven't noticed any NOx problem, and my fuel economy is the same as before (even with the blower).

On a stock Marauder you may observe a decrease in fuel economy (maybe a couple of MPG). Also, it is probably illegal to remove or deactivate the system. In addition, you MUST adjust the tune to safely remove EGR.

EGR, I don't need no stinkin' EGR.

I would like to know how you determined you do not have a NOx problem? You are looking at emissions testing data?

That's my version of a joke. Part of my blatant disregard for the environment.

That said, I haven't noticed a NOx problem. I haven't looked for one either...

Everything he said except adjusting the tune to safely remove the EGR.
Who told you that one?

In a sick way I find this hilarious.

Are you saying that you can just remove it and everything will operate normally?

You would at least get a check engine light, no?

[TooManyFords]

I removed mine and just changed a variable in the computer and was good to go. Oh, and I removed the EGR tube, sealed the header shut and capped the tube on the EGR valve. With my new setup I won't have room for it!

Cheers!

Yeah, what you said.
No tuning necessary cause EGR doesnt function at WOT.

[fastcar]

I hate EGRs in principle. They filthy up your intake, heat the charge, heat the engine compartment, and add more junk under hood. I want to take mine off.

Problem: this is the best thread I can find on the subject, and it frankly stinks.

Maybe because it's in Shop Talk, not enough people have posted their experience here with this mod.

I'm going to try and revive it. If it doesn't work, I'll put a new one into community discussion.

We need more discussion about:

1. Engine light/computer codes. Will taking it off throw any?
2. Computer tune. Does this need to be altered? If so, why?
3. Driveability. Are there any problems? Is part throttle driveability or smoothness sacrificed?
4. Any other issues?
5. How do you do it? Did you plug the manifold, what about the intake, where did you get the plugs?
6. MPG. It's beginning to matter :eek: DID YOU NOTICE A DIFFERENCE. Why should the egr change anything? It's not suppose to be a mpg device.

If anyone thinks of other issues/questions please add.

If you have any experience with this mod PLEASE POST WHAT YOU KNOW!

I'm telling you. I start a new thread and get people complaining about not using existing ones, then I use an existing one, and get people complaining I didn't start a new one. It's kind of funny...:lol:

We still need more discussion about:

1. Engine light/computer codes. Will removal throw any codes? Will it still pass the OBD II scan?
2. Computer tune. Does this need to be altered? If so, why?
3. Driveability. Are there any problems? Is part throttle driveability or smoothness sacrificed?
4. Any other issues?
5. How do you do it? Did you plug the manifold, what about the intake, where did you get the plugs?
6. MPG. Some claim it hurts your MPG. DID YOU NOTICE A DIFFERENCE. Why should the egr change anything? It's not suppose to be a mpg device...

I spoke with Mike at Dez racing yesterday. He said you need to go into the tune to 'turn the EGR off'. But he didn't offer an explanation as to why.

I think you can get away with more timing during EGR activity, than without it. The "there is too much clutter under the hood" argument does not work on newer vehicles. All that "clutter", is why your car gets twice the mpg that something carbureted and similarly powerful would have gotten years ago, while burning clean.

[05LXSport]

On an OBDII mustang I plugged up the EGR tube that ran from the header tube up to the EGR valve, the computer didn't seem to care, the EGR valve was still attached and "functioning", it just didn't let exhaust gas into the intake manifold. Wouldn't this work?

[fastblackmerc]

Why not install the blockoff plate between the ERG and the intake?

Wouldn't this work?Thanks for you input. That was a good experiment on the Mustang, and your results were worth noting. But I don't want a tube that is 500F connected to my intake manifold, thank you very much! I want a cool, dense inlet charge. Notwithstanding, the info is definitely helpful:up:

Why not install the blockoff plate between the ERG and the intake?Great idea! Thanks. BTW, who sells it?


I'm moving this thread to 'Community Discussion' because it's just not getting much action. I think there are a lot more folks with knowledge and experience on this topic than have chimed in...

thats true...the "use the search function" is the mostly what the site is made of:rolleyes:....

Hey... I just used the search feature to check out using the search feature and then I was told that the search feature cannot search the search feature... so I used the search feature to search for searching within the search feature and that turned into a search on featurizing the search feature features well searching for featurizing the search feature caused and rift in the space time continuum and now we we are all doomed.... so there you go....

btw.... ain't it a Federal no-no gig to remove the EGR? I need to search that....

See responses next to your questions..........



We still need more discussion about:

1. Engine light/computer codes. Will removal throw any codes? Will it still pass the OBD II scan? ***** Yes, it you remove the EGR valve and do not turn it off in a tune, it will throw a code.****

2. Computer tune. Does this need to be altered? If so, why? ***** Not for tuning purposes. But yes to turn the EGR off *****

3. Driveability. Are there any problems? Is part throttle driveability or smoothness sacrificed? *****No problems. Nothing sacrificed. *****

4. Any other issues? ***** No *****

5. How do you do it? Did you plug the manifold, what about the intake, where did you get the plugs? ***** There are 2 parts available from Ford directly that cap the port on the exhaust manifold (a screw on cap) and block off the port on the intake manifold. I used those. *****

6. MPG. Some claim it hurts your MPG. DID YOU NOTICE A DIFFERENCE. Why should the egr change anything? It's not suppose to be a mpg device... ***** I noticed no difference whatsoever. However, mine is probably one of the most modified Marauders out there and my gas mileage is bad all the way around. I wouldnt really notice it unless it was a big difference. *****

I spoke with Mike at Dez racing yesterday. He said you need to go into the tune to 'turn the EGR off'. But he didn't offer an explanation as to why. ***** It will throw a code. The engine expects something on the other end of that wire to accept the signal to open or close. If not there, you get a code. *****
