Hello everyone, as the title suggests, I would like to ask you if it is close the EGR valve physically or exclude it by using the map. The differences between the two mode? there are, not there or they are mild?
Thanks in advance.

Thanks in advance.
a closure is made well and includes all of the two modes.

Hello SanJoe, there is no absolute rule...
Some euro3 you allow the exclusion physics even without the act electronically, and without present no light egr on the instrument panel; the other (euro4) allow you to act physically accendendoti the light on the picture, but without recovery; the euro5 instead if you just physically can't go into recovery... This does not apply absolutely to all of the ecu, but in principle it works well.
For example, I've a Alfa 147 115hp that runs from 50000 km with the EGR plugged physically, and I ripped off all the EGR system from the exhaust manifold to the intake without any removal of the electronic and zero problems.
In my opinion the best method is to exclude it electronically and physically with beautiful caps to prevent the formation of unnecessary turbulence both in the exhaust manifold and the intake...
With regard to the feelings, depends on the way of thinking of the various ecu, on the euro3 between the exclusion only of the physical or electronic should not be any difference, but from the euro4 in then I think of you as the ecu is the calculation between the quantity of air that sees sucked in and the amount of exhaust gas that should recirculate...
If I say wrong correct me.
I have a fiat punto gt 1.3 multijet 70cv ... it should be euro 3. Best thing to do according to you?
As usual, the best solution is the exclusion is through the map and physically, because I believe that it is a euro4 and not euro3 (if I remember correctly, the first 1.3 are all euro4). If you do not want to intervene immediately electronically, you can also parzializzarla through the thickness to be interposed between the actuator and the EGR itself.
About 1.3 normally if there are problems you trafilo from the valve to the exclude only electronically.
Hi, in that sense trafilo from the valve?
In the sense that the valve is closed there? the passage of gas in the intake. As it normally should be. While it happens that with the time the deposits on the valve does not make the pi? close properly, and also the valve is closed, the remains of the dirt which does not allow the seal.
thekid I think means that if the egr valve has a good seal between the exhaust and intake manifold, without putting the cap on, then excludes only via the map.
Even better would be to delete the egr plug manifold, remove the heat exchanger that cools the exhaust gas and the relative water circuit, finally, plug the exhaust manifold.
I was on my 147 jtd 8v 115hp euro3 I did just that... I ripped it all away and plugged directly on both the collectors...
The first thing I noticed was the improved responsiveness and the significant reduction of smoke; hence'.
All without a remap and without even exclude the egr from the map!
? a work by making a mechanical or ? simple and I can try it too?
by removing the whole apparatus of the egr the engine but it takes? more time to warm up
It all depends on your expertise, I have done alone, but the system of the 1.9 8v is more simple... the hassle is that you have to remove the battery and tank battery.
It is true that it has more of a warm-up, but if you saw how the egr combines the manifold, you wouldn't think twice!
I've taken for years now
Just think that until a short time ago I had a alfa 159 1.9 jtdm 150 hp with dpf... the same alfaromeo provided a "plate of limitation egr", which I bought as a sample to be able to play the other and do a variety of tests! With the sole plate already decreased jerking and regenerations...
I hope to do that ... Someone have the same engine?
for lived experience should close with sheet as with the time the valve gives way, and as it engages and opens against the force of the spring.and then that costs in exchange for serenity
I confirm the council to request it via software that mechanically (cap) I had problems especially on the alpha form only from the map...gave me error inconsistency in air mass, objective,very likely, why? trafilava..
With regard to the JTD, the euro3 just close them physically, instead, from the euro4 (JTDm), we must also act via software.
You exact the € 3 do not give the breakdown, about € 4 you just have to bring to zero the two panettoni one of 1c4b6e and 1c4b88 and the other between the 1c4c3a and 1c4c54 I speak of EDC16C39, however, to the speech of the temperaura enough already? close the egr, which puts us more? to heat up.
I believe that we must also act on other curves for these ecu...wait one more good...Quote:

I own about these ecu I go down panettone...
I speak from direct experience on my machine alfa 147 JTDm 150cv that ? been excluded from a workshop in just this way, I don't want to give info that are vague or incorrect!Quote:

On the Alfa group, even if they are euro 3, at least to me, the light comes on (not immediately, but after a couple of days...) if you do not act via software, why? error ("incongruity mass air target") instead of on the fiat example dobl? 1.9 jtd is not that error simply because? not ? diagnosis....
Ultimately, it is convenient to tapparla or remove it altogether?
In the meantime, tap it, both electronically and physically, then if you want, just you can delete it completely...
