so if i do this mod it wont hurt anything?

anyways if you actually can get this whole clean air recirc cluster fuck to work, you still need a filter for the new air so you dont suck shit up...do we even have enough space down there for a filter?

Let it die. I don't fault Wenis Prinkle for trying, I think it was worth at least exploring. But, it isn't going to work. Time to move on.

If you mean a regular EGR delete, no, it won't hurt anything. But you will get a CEL light to come on. Somebody in either this thread or another one said that Mazda did a write-up trying to explain the importance of EGR to the MZR. But that seems contrary to everybody's experience who has done it. I've done it to mine and I'm glad I did, but, I wish I didn't have the CEL.

There are several ways to plug the EGR line. Whoosh makes the plate and plug. I had mine welded on my intake manifold.

well... last night during my OCC install i decided to investigate my theory on modifying our egr valves to draw in fresh air rather than exhaust fumes and by doing this without using any blocking plates or taking off the egr or whatever. my fresh air coming into the exhaust side of the egr theory so that you wont throw any codes from (egr low flow) or (manifold pressure not consistent with egr opening and closing) ..... was completely destroyed after actually taking off and inspecting our egr system up close. there is absolutely no way to get in between the egr valve and the exhaust gasses because the damn thing draws exhaust and coolant in threw the side of the head, the tubes coming out are supplying shitty air to our IM's and then supplying coolant to our turbos it looked like. so yeah we pretty much have to leave it on there if you dont want engine lights, but after doing some research and data logging the egr valve i found out that it only opens whenever your just normal cruising in vacuum. at idle it stays closed and during boost it shuts off!! so pretty much the egrs exhaust fumes wont effect our cars whenever we want to haul ass, so whats the real point of blocking it off anyways if it already automatically shuts off when u actually really want fresh air in your IM. So fuck trying to get rid of the egr. How about instead of messing with the egr try installing a nice oil catch can set up, then your actually doing something that will help the performance and longevity of the engine.
here is a diagram of what i did last night.

You don't know your ass from your elbow. :tool:

The EGR transfers soot from the exhaust to the intake manifold gunking up the intake manifold valves.

The Catch can is for something else.


So, either get your facts straight or quit your theorys.

I think he was thinking a catch-can might catch the soot, but, I rather doubt it.

OMG another fucking idiot!! with nothing logical to say back LOL what is it with this, is it stupid people day on this website?? i know more about this motor or motors in general than u ever will!, and listen up u moron, our egr system does not transfer soot from the exhaust system like most other cars, it draws in expelled burnt fumes from the inside of the head before it even reaches the exhaust system, and most of the soot your talking about is from the shitty oem PCV system letting dirty gas and oil and shit slip by the rings right back into our intakes causing dirty valves more so than normal because of the super high psi direct injection fuel system that our cars have, so please dont say anymore negative things to me or anyone until you actually understand how our motor works!!! i was simply stating that on our engines the egr valve receives the exhaust gasses threw the side of the head, and coolant also flows threw our egr system. on any other car the egr gets the exhaust gasses from a tube that goes to the exhaust manifold, with this traditional egr set up its easy to just block off the exhaust output to the egr and just let fresh air run threw the egr, eliminating exhaust gasses from entering your intake and still allowing the egr to stay in place and do its job so the ecu wont throw codes. the point i was trying to make is that its impossible to do that fresh air egr mod on our motors because our egr system is designed completely different cause it exhaust source comes from the side of the head so there is no tube connecting the egr to the exhaust so its fucking impossible to stop it from pumping exhaust gasses into our motors, unless you just block it off but that's the gay way to delete the egr because u will get check engine lights from no flow and manifold pressure related codes. so unless someone can figure out how to re-program the ecu and turn the egr system off somehow. the current egr delete mod that just blocks the flow will keep the exhaust gasses out of your manifold but will cause more headache than performance. plus think about this our egr system is programed to only vent some exhaust gasses only during normal cruising in vacuum and completely shuts off during idle and boost so the exhaust gasses from the egr wont have any negative effects on our engines performance other than the small amount of exhaust gasses it vents out when cruising normal. the exhaust gasses expelled from the egr are not nearly as dirty as the crap going into our engines from the stock pcv system, The benefits of running a nice OCC system far out weigh the current benefits of the egr delete. The oem PCV constantly pumps not only exhaust gasses like the egr does back into your intake but also a good amount of un burnt fuel, dirty oil, contaminated air ,ect.... look inside your intercooler, or turbo inlet, u will see all kinds of oil residue stuck or puddling in your intake system. So like i was trying to say before, rather than fucking with deleting your egr valve, install a nice oil catch can set up and you will help your engine in so many more ways than just blocking your egr could ever do!! by adding a nice OCC set up you will stop all the sticky blow by fumes, oil, fuel, dirt and other contaminants from going back into your intake, Plus you will eliminate hp robbing positive crank case pressure away from your pistons during wot! and wont allow all the pressurized contaminated air back into your intake! this will defiantly keep your engine cleaner and lower your chances for detonation!!! so until someone figures out a legit way to delete the egr, the OCC is a way better choice and doesn't cost a lot of money. Just my opinion only trying to share valuable info with you guys and i dont appreciate it when some young idiot that just started learning about engine performance thinks he knows it all cause he plays on the forums all day and puts others down to make himself feel cooler, well it didnt work buddy your comment was stupid and i proved u wrong,so dont fuck with me again until you got a good 15 years experience in modifying / tuning engines. RETARD:neener:

Someone else pointed out that even if you could get fresh air into the EGR, it would STILL be a bad idea as fresh air has OXYGEN which would total hose your a/f mix. So, time to just let this idea die, ya think?

Its time , its over LOL:arms:

Another e-thug here that must have passed the 'stupid' filter over on mazdas247.

Diesels have been having the same EGR/soot issue we are having. It's not PCV alone. Look at all those running a OCC and Meth and still deal with carbon all over their intake valves.

Many Ford guys unplug their EGR. Thats not an option for this car. The VW diesle owners are constantly taking apart their EGR system to clean it.
The military runs their turbo diesel hummers at WOT to blow the carbon out of the EGR system. It's a DI issue. With all your claimed experience, it's sad you don't think out side the box.

As abovementioned the reason our engine is so "sooty" is due to the incomplete atomization and combustion of fuel when injected at low pressures. It's a byproduct of direct injection unfortunately and this is one of the reasons we have a sooty tail pipe and sooty intake tract. PCV blowby aggravates the issue but the exhaust recirculation system does result in soot build-up in the intake manifold.

"open during boost, closed during vacuum"






Where does the boost come from on this N/A motor?

huh???.....he talkin about speeds...3 and 6...??

i dun get ur Q?...what is naturally aspirated?

*sigh*


look harder at the picture, and think to yourself, "where does the boost come from". I think you'll find your answer, or lack there of.



It was a joke, but you kinda murdered it... thanks.

lol...sorry:loveweed:

It's okay, i'm over it. Thanks for apologizing. :)

r u serious? i drew that in like 2 seconds just to show how to connect the lines on my OCC design i installed on my speed3. im sorry its not a perfect drawing dude, geeewizzz..... other than my crappy drawing looking like an NA motor what do you think of the OCC design? its intended to work with our turbocharged engine, im just a lazy artist lol

more pictures plese

lol

Any 09's with the EGR delete? Curiouse to know if there is a CEL with an EGR block off on the 09's like on the previouse models. If your uncertain, don't reply.

I'm certain of the answer, but I'd rather answer with a question.

Why do you think 09's wouldn't have the CEL when the system is the same as when it originated in '06?

Possibly the ECU was tweaked differently. Just pushing my luck.

I would like to delete the EGR and not get a CEL. Between winter wheels and the EGR delete, it's sure to look like a chrismas tree.

If you were asking about a '10 model then maybe they changed something, but I wouldn't count on it. No matter what they changed, it would still trip a CEL and the question would be is it defeatable which I don't know personally. As far as an '09, the EGR is still the same as the others. You'll get a CEL fo sho. We all need to ask COBB to please remove the EGR CEL like they did for the '02 sensor on the latest revisions. Obviously they can do it somehow, but ATR can't.

Cobb feels they have a monopoly on the tuning competition because they're the only ones offering flash tuning on our cars vs the evo/sti world has a dime a dozen methods from boost controllers to opensource to utec to AEM. So in our cars case they'll take their sweet old time because they know we're limited to them. :nutkick:

The more Cobb does with their AP the quicker I'll feel the need to buy it.

On a side note, whats the cost of an AP with ATR?

ATR is free. The AP is ~$700, but you can get it for a little less from vendors.

i'm still stuck on if I should get the AP or the stand back,,...

what are ur opinions....

what are the pros and cons of them both?

if there is a thread on this topic please lemme know or post a link...thanx

:loveweed:

I have the AP and love it. ATR = win.

You can see the fun I am having with it here:

I really cannot comment on the SB, since I do not know anyone with it.

I elected to go with the AP due to it being much cheaper (after you factor in the FCF and PnP harness required to be comparable to the AP), has a cleaner install, and actually alters the ECU's tables instead of just intercepting/fudging the signals.

With that said, everything I have from CP-E is top notch; and I imagine that the SB works well.

The SB doesn't compared to the AP. The SB + a few flashes of an additional ~$500 compares to the AP.

I didn't like the SB on my car. I think the ECU constantly tried to correct what the piggyback was doing. I saw some strange shit while it was on there. I sold it and bought an AP after trying a friends.
