I've done mine recently on a garage in my local area, they done it from ECU software and they said I can revert it back easily because they only done some parameters for egr, but now after this something is wrong because my engine is pinging or knocking sounds, particularly during acceleration on heavy load, I think they forgot to adjust from ECU the flow mixture between air and petrol/diesel like you said 😢 what can I do now..some advice please 🥺. Thanks
Egr is a terrible design. It's so stupid. It causes cars to run ultimatley worse, consume more fuel and break, I thino that's worse for the environment in the long term.
EGR reduces throttling losses at part load and increases fuel economy while decreasing the hydrocarbons necessary in the exhaust to reduce NOx in the 3 way catalytic converter.
A properly working egr INCREASES mpg. It adds inert gas while cruising so less fuel is added due to less oxygen. Therefore, the throttle plate has to be opened slightly more which reduces pumping losses. At full throttle the system is DEACTIVATED therefore peak engine performance is not reduced.
Exactly. EGR is poor man's cylinder deactivation. It reduces throttling losses and improves fuel economy by about 5% at cruising speed. And way simpler.
Bought a 2016 sprinter van that already had the delete done (legal in my province in Canada) can gets amazing fuel economy for its size 10L/100km~. Motor should last nearly forever…
Kinda sus that EGRs are legal in your province. Which one? Surely not Ontario? I'm in Alberta; no idea if it's legal or illegal here, but I feel like it should be illegal, lol.
@@Ahomesteadersdream hot damn. I'm in Alberta as well. Do you suggest I delete my EGR in a 2008 Dodge Grand Caravan? I'm good either way, but I do know that my EGR is probably clogged up nicely at the minimum. Thanks for getting back to me!
Some vehicles are a blanking plate only . Some use a small hole blanking plate , Why the fuss the later models may require some electronic defeat device also . Remember to install a water bypass to egr cooler . Egr supplied air is typically hot and full of carbon . This air is inert ,will not burn or make power Clean combustion air will make a little more power and slight better fuel economy Remember all the egr gasses contain debris . this must be removed every 100,000km
I guess you are talking about diesel engines, as EGR is not common in otto circle. Diesel engine do not knock from a lean condition, this is exactly how they control power generated, inside the operating range, more fuel, more power, less fuel, less power...
Its not simple: block flow, and you throw a p0401 code: the "insufficient flow" is actually driven by low temperature in the egr unit while accellerating and with the check engine light on... you just went blind to other problems you might like to know about. A discrete delete is a nuanced project: create a signal board that can mimic temperature sensor response in the approximate 2400 to 3500 rpm range where an agr is active and do it in real time. And as you point out, fuel curve then has to be re-tuned.
Messing with emissions related components isn't illegal in all 50 U.S. states it's actually legal to do since it's the only way to replace or repair said components. People remove their whole air box replace it with a wider straight-piped K&N intake with a HEPA filter on the end for more airflow when it comes to cold air intake, delete the EGR and install high-flow aftermarket downpipes, Catalytic converters and catback exhaust systems all the time to increase horsepower along with the adjusted fuel maps by also decreasing backpressure by giving the exhaust a wider opening creating negative air pressure which works in Tandem with the EGR delete and the Intake upgrade because negative air pressure on the exhaust end ceates a vacuum effect that in turn draws even more air into the intake manifold, it's a very common "upgrade" especially if you need to repair or replace your Catalytic converter on an older vehicle especially a Honda you might as well just go the custom intake/exhaust route and push the envelope as far as you can when it comes to emissions this is especially common in my home state. The ECU has to be reprogrammed to provide more fuel, a process much easier to do than described in this video especially of you have professional experience and a Dyno-Tuner especially with Hondas easily the most common vehicles on the road more people likely drive some form of Honda accord than any other vehicle it and it's components are the most stolen vehicles and vehicle parts in America because they're also the most common vehicle which is why if the bolt pattern and offset match someone will steal the sexy 17"x8" alloy wheels and fancy low profile tires pretty much every car rolls off the lot with nowadays right off of your 2019 2.0T AWD Accord just to throw them on a built out and turbo charged '04 sleeper. Hondas only need a laptop PC with "Hondata" brand software and an OBD-to-USB cable and Hondata has all the different settings laid out like a Microsoft Excel spread sheet where you can literally go to the rev limiter or the VTEC engagement setting's little box and just double click highlighting say the 4500-5500 RPM VTEC engagement value and drop it and set it to say 2500 or 3500 RPM just by deleting the old value and typing in a new value meaning the VTEC will turn up earlier at a lower RPM range (another cheap way to increase torque, horsepower and acceleration in such cars) but likewise the fuel maps need to be adjusted as well so that it knows to provide more fuel as VTEC is literally a form of forced induction that for some reason isn't legally considered forced induction and it also basically because each camshaft has multiple profiles or "faces" this almost makes a SOHC a DOHC in a way which is why small and mid sized Honda engines are so powerful despite their lack of displacement the D15 SOHC is a known powerhouse for cheap 350-400+ hp turbo builds and it's a 1.5L i4 SOHC but with a larger throttle body, larger Fuel injectors, a fuel pump from an S2000, a larger straight-piped intake, high-flow intake manifold and exhaust manifold headers, aftermarket camshaft, highflow downpipe and cat and a larger diameter like a 2.5" catback exhaust with a smaller muffler and a 4" opening at the tip, low compression pistons and a Kraftwerks turbo charger in a '97 hatchback chasis It's a 400+ hp monster with over 300 ft/lbs of torque and since it weighs nothing it will beat a modern car with 400+ hp because it's lighter in weight and FWD is more efficient than AWD/4WD and RWD because there's less mass to the drive train and no torque converters for all the differentials which all decrease wheel horsepower and torque, an FWD car's wheel horsepower will always be closer to it's hp rating at the flywheel because it has the fewest number of other mechanisms separating the flywheel from the drive tire it's the closest internal combustion drive train to the direct drive of electric motors it's just flywheel-Transmission-transaxle-drive wheel in an automatic and flywheel-clutch/pressure plate transmission-transaxle-drive wheel in manual no differentials or torque converters to alter the horizontal orientation of the torque on a coordinate plane which knickles and dimes your HP away with each torque converter. My home state's laws simply say that a cars exhaust emissions and it's sound must not be "excessive" while setting no actual objective standard or definition for what "excessive" is leaving it up to individual interpretation and the specific parts of the laws pertaining to intake/exhaust systems is it says nothing about the intake so adding a short ram air intake or a K&N filtered large diameter highflow straightpipe intake or doing an EGR delete isn't even mentioned so since my state also operates on the basis of "you dont need a law to say you CAN do something, as long as there's no law that says you CAN'T do something you're allowed to do it" and the law doesnt address the airbox/intake and intake manifold or the EGR valve. I believe there's a Federal Standard for emissions and my home state simply says you can't have a "straight-pipe" exhaust it has to run through a "muffler" at the least to dampen the sound though no specific decibel levels exist in the law so as long as you have a muffler your exhaust can still be as obnoxiously loud as you want it to be and only vehicles "20 years old or newer" need to pass the smog/emissions test. This coming year my daily driver will be 21 years old and she won't need to pass an emissions test in my home state. My Catalytic converter is gone and I have a straightpipe in terms of just a downpipe dumping out smog, it's insanely loud, faster but while there's no noticeable "knock" one knock sensor is throwing a fault code and cylinder bank #1 which I assume is cylinders/pistons #1 and #3 are "running lean" meaning the air fuel mixture has too much oxygen and not enough fuel because the decreased back pressure of the straightpipe is creating a vacuum pressure that pulls more air in and I've also removed most of the unecessary airbox components so it's just a straight intake pipe to the box and filter taking air in as it passes through the front grille and radiator so its pulling too much air in and the fule maps haven't been adjusted to match it. I'm stuck between playing it safe and just having a custom intake/exhaust that will make my care faster and more efficient and is still guaranteed to pass inspection right now or do I wait and just swap out the airbox for a K&N filtered pipe and replace my downpipe with a highflow one and straightpipe it to a 2.5"-3" catback exhaust system with a 4-4.5" tip and then get it tuned for that with no cat cuz come January 1st 2025 my car doesnt have to pass emissions testing.
I drive a Hyundai Santa Fe 2.0T. The exhaust system of my car gets clogged frequently because I only drive 4 miles daily. Would deleting the EGR help with the exhaust problems? I live outside the US.
Yes. Your engine never gets hot enough to burn it out. It never really gets hot enough to ever clear it when you do get the motor hot. I don't want to void my warranty or I would do it now. As soon as it's up, it's getting plugged. In a cummins you can let it in tact while buying a kit that can plug the in and out of the egr. This gives it the appearance of the system, but it doesn't function. Just somthing else to think about. When these diesels were mandated to use Def or that blue stuff for emissions, a lot of politicians got richer. It's literally the same stuff we spray on fields called urea, aka nitrogen. We know this isn't about saving the planet because it chemically turns the carbon that would just fall to the ground and turn into dirt, into methane. They say methane is a more potent greenhouse gas. Now why would they want to do that?.... I know several people who took all emissions stuff off their cummins powered trucks. They increased their mpg from 18 to 24 while increasing the power.
Zdravo imam 2.0hdi i imam dvije metalne plocice da ga “izbrisem” dali te plocice samo stavim izmedu da ga blokiraju ili da ga fizicki odstranim te montiram plocice ?
Zdravo, Morate da uđete u kompjuter automobila i modificirati ga tako da zna da ne koristi egr. Ako to ne uradite auto ce imati problema zato sto ce misliti da je egr blokiran.

Brilliant! Thanks for the clear explanation. Think I`ll stick with legal side here in the UK. But that`s an individual choice so each to their own. Good luck everyone!
PCM knows if engine gets to much air through the O2 sensors and will adjust the fuel accordingly. Plus there is a MAF sensor, MAP sensor so lots of ways to determine the amount of air in the engine. Just replaced my EGR with a cheep one and after a while my Ford gets limited to 3000 rpm (with EGR codes) so thinking of deleting the sucker.
Not necessarily. Older cars had a hard time getting a "lock" on the exact exhaust flow in the EGR. Late 1980s and early 1990s Honda Accords would plug EGR valves, run lean, and burn exhaust valves.
your explanation on engine knock is out wrong, cars are equipped with knock sensors on the engine too correct this. pumping exhaust gas into back into your intake does nothing more than carbon up your engine. the carbon monoxide within a month turns into carbon dioxide which plant's grass and trees use it a food.
@@xothuggerI suggest watching EGR video on "driving 4 answers". EGR actually improves efficiency, but not on high milage, badly serviced flogged cars...

No such thing as “help the environment”. The carbon demonization is the biggest hoax of the 21st century. The more carbon, the BETTER for plant life.
