Hello, can I post calmly, on the contrary a another discussion about valves swirl I've already posted, but at the moment my map is original, only with egr off, and then has an area at the end that is different from the ori, but I don't understand what it was (checksum, of course, those are just a few bits).
To me at the moment no error, only that the car is less responsive at low revs, and then give a strong push among the 2800/3000 rpm, you hear a lot in 2* and 3* gear.
Given this jerk I think of all, the turbine has been rebuilt recently, and we had to make a half turn of the screw in the dipstick otherwise you really shooting me, I've been dreaming about!
Go to understand if this difference is really the fault of the swirl missing.
I figured it out. Perhaps before changing the turbine was too reactive, because the geometry is not opened the whole. Now, however, it seems that the geometry fails to close.
No prior to repair of the turbine the car up to the 3000giri was dead, then suddenly 3000giri started to rocket!
In the past, before the whole story of the game was a missile since the low reggimi.
Now with the turbine regenerated it's much better to be low compared to periods before you re-key it, but these steps, if I accelerate gradually the shot, does so at 2800/3000 rpm, but if thrust the pedal 3* for example, triggered by 1800 rpm, up to that regime rises a little more slowly.
Hi guys, I'm new here, I wanted to ask you another thing (I motato now that starts to get hot and travel with the windows open), the turbine whistles for a quite a while, it's nice sound and I agree, but I don't know if I should worry about because he has been regenerated just 10000km ago', what do you think? As you hear the whistling of your turbine
hello, but still spins with the vts adjusted by your mechanic? I would not like having a setting wrong in the long run it greets the turbo (assumption mine), anyway mine also feels a little a bit, and the sound of a prex and a little because I kat and fap. The whistle accented and symptom of balancing wrong.
but instead of 1000 guesses to make a log with pressure objective/measured and % closure geometry is too difficult?
Actually it would be the first thing to do
How to adjust unfortunately, I only have half a turn of the screw in more, if left as it is returned from the review, the car was very slow to climb rpm.
Of tracks with the MES I've made several, but unfortunately I do not know how to interpret them to the maximum, what is known is a trend that is strange (in the sense that with the throttle at about half, the pressure shoots up to peak 1,6/1,8 "would be the 2.6/2.8 mes", and then decline after 2800 rpm, and just in that moment that you feel an extra boost from the engine), now I can also make new, or to see what values I put in those facts.
As you are interested in? Doing some testing and sinking of the pedal? Or accelerator
Constant?
However, I do not know what is the value of the geometry, now I do not remember him, in those that I have done I have placed sure accelerator, press. Measured, press. Objective, and the number of laps.
Valve I remember the value valve parzializzateice flow, (if I'm not mistaken are the swirl), what is the value of the geometry that escapes me? Maybe I can saw and I don't remember.
Aaah yes indeed! Not as I remembered you, I think I put in some logs, ok as soon as I have the netbook at hand them I enclose.
For the offence, the machine goes, but has this strange behavior, in the sense that it is not responsive to the pressure of the pedal, it responds a little later, and then usually at around 2800/3000 rpm you hear a step, as if there was a moment of blank and then recovers.
The log graphs are good the same? Or where do I find the log as a table?
The csv that will save the mes...
Perfect, then I'll check them and I try to attach the ones that you understand better, some of the throttle is constant and the other with the accelerator to the bottom.
here is some log that I did some time ago, only in one there is the opening of the goemetria, there, and also the valves opening in the game, but to me they have been removed.
that strange thrust the known right around 2800\3000giri, when from the graph, the valves are fully open.
if I reset the duty on the map as you say, that improves something? or is it just a coincidence?
As I see it, you always have tons of an overboost, to any regime and any IQ.
then geometry incorrectly adjusted.
second thing, you need to find an interface that works better because you have a refresh bad, even with only 4 data puts us a second and a half between each line and the other. you should have 2 or 3 PER SECOND at least!
excuse the ignorance your ECU is a C8 or C39?
Sorry qnche thou my ignorance, but what do you mean by IQ? The load intended by the ecu?
For the veometria unfortunately, only a small adjustment to anticipate it, but if I remember correctly, I had a lot of spikes even before, if I have some path of the turbine before it will work.
As an interface I have a miresa elm327 wifi, I have seen the kit with the cantiecar (from my mechanic) but for a hobby, perhaps, is wasted! You could recommend something?
Ecu EDC16C39
go to the website of the MES to see the recommended interfaces depending on the car and the modules in which you wish to enter.
lately I have seen several problems with the elm327 "new", 1.4,1.5 etc etc.. from the site it seems that you can also use the KKL but I have never personally tried it.
all of them are strictly USB ONLY!
I correct myself. The cables kkl only works in kline.
Then elm327 or obdlink sx.
The second is said to be faster but I never found confirmation.
I also have a kkl and for my ecu should be fine, then I have to try and see how latency if it goes best with them that is usb.
For the rest, like an overboost can be a problem with the valve that manages the geometry? Or if it does not work correctly, it usually behaves with empty pressure, and not peaks?
can be various things.. make a log short and simple. third gear, from 1k to 4k rpm the pedal all down. put in pressure-demand and goal, opening the valve an overboost, and the amount of diesel fuel. if you think you'll always have too much pressure you have to try to adjust it and then redo log, etc..
this is the log always done with elm, unfortunately.
test acceleration of 3* from 1k to 4k rpm with the pedal all the way down.
what do you think?
Yesterday I went to my mechanic for a couple of services, and I took the opportunity to do a check since I always have a strange behavior, like a vacuum under the 3000giri, so I insisted on giardare the tubes of the air, those of the turbine nom we controlled for mancanzadi time, but we have seen one that is just below the egr valve, in practice, from what I understand there is a sort of box that also filter the air, we get a tube if I'm not mistaken port depression, and then from this box escomo other two tubes, one of these two enters in a valve and then it continues, all of this system gestise pre-curved valve soft off (another one of my problems was off with jolts), look at them we notice that one of these tubes (a piece of a few centimetres and that went from this box up to the top of the valve) was deformed and choked!
It was in the casino disassemble the
Box, and replace comfortably the piece of tubocino with a new one, but soon after turning it off
The engine is back lerfetto as perhaps has never been since I bought it!
Think a bit of a cabbage, and you will be viewed choked what combines!
I hope I can check more in the also those that implement the geometry, hoping to be a part of the genre too!
You with the pipes of the geometry have you ever had any problems?
here, pressure low is low pressure and not high, then nn is due to the limiter, but to a pipe split or the egr valve not sealed well when closed.....
I have no errors concerning low pressure or high, only that the machine does not push well up to 2800 rpm.
For the egr is flanged for a long time and excluded from the map, then I don't think that afiati from them.
I'll have to check the rest of the circuit to depression, if I am going to exclude the pump fi depression works, the box and the valve that actuates the butterfly softoff com related tubes are intact, and I serta, to check for safety the tube that goes from the pump to the box, and the one that continues from the box and goes to the control valve of the geometry.
Then a control to those of the tubes, I'll have to do it, stayed at the dtc for now, the only thing that was abolished was the egr, everything else is original (I have the file read in the ecu, by me, and compared with those ori), I changed excluding valves swirl and as soon as possible I write.
For the rest, I'll see how it behaves.
Good evening, after a long day I have written the file in the ecu with the change of the valves, swirl off most egr off, and then I removed mass air flow sensor to make a proof given that the machine I was strange at low rpms, and at around 3000 rpm, it was a snap of power, so he felt very in 2' and 3' gear!
Now, the fact of the map swirl off, it will be that I disconnected the mass air flow sensor, but it seems to me that goes a little better and face less shooting sharp those turns.
However, from the diagnosis to me marks the failure on the air temperature and mass air flow sensor (disconnected), I read on the forum that is used to measure the mass of the air, but as it says in the diagnosis, it seems to measure the temperature! I could help figure out if the mass of the obtained making the calculations according to the temperature? Or something like that? Or the air mass sensor is another? The mass air flow sensor might push me to have that behaviour at 3000 rpm.
Sorry for the many questions.
A greeting

I'll tell you, I honscollegato yesterday afternoon, and I've used the drive, I noted the failure, but does not go into recovery, and I have almost the impression that it goes better, now I use relax this morning, then before or after lunch, the associate myself, and see if the well-known differences, in order to understand if I have to replace it, and what deco to buy more!
For the geometry in part, you may be right in part, no! The turbine was rebuilt 12k Miles ago and adjusted the bench, (according to those who made it), but mounted so the drive to the low reggimi was not to be for nothing, so with the mechanic, we advance the hand one-half turn on the adjustment screw and now it's better!
However, he has always had peaks of 2,7/2,8 in diagnosis, even before you adjust it.
Yesterday with mass air flow sensor disconnected I did a bit of testing, and in all has been around 2,65, from what I understand I should astare not much on the 2.5 as the peak, and now maybe this oiccola difference is docuta to the adjustment that we have moved.
But according to you the mass air flow sensor as well as distort the reading air mass, it can also cause these pressure spikes? What do I know! Maybe not reading the mass air, does it feel more time in the closed geometry? I'm going away for a rule, unfortunately I have a lot to learn.
Greetings.
then, for the spikes you might have a problem with the pierburg, then with regards to the mass air flow sensor before changing it made a diagnosis with multiecuscan and you read the following parameters: air mass measured air mass, objective, turbo pressure measured and objective, the total quantity of diesel fuel (mm3) and rpm of the engine. Do a log pull in 3rd gear from 1500 to the limiter and then tell us the data so I can help you
*overbooster
Before regenerating the tjrbina the car had become dead under the 3000giri, it would take an eternity to take biri, and then get to those around and starting to blow! It was the sharp shooting! And then, it consumed oil.
Now the turbine is not leaking more oil, and to lower reggimi has taken place, always with a little tug around the 3000giri, but better than before!
For the peak pressure I don't know why I only began to equip myself a little bit!
*enrico
For the valve to some suspicion I have, I have to see when I can get help from the mechanic to dismantle and check the tubes if they are intact, I think they will not do it alone!
For the log of the mass air flow sensor, aspetteró well buy a new interface that is a little better than the elm wifi, but for the pull to the limiter, you mean up to 5000giri? I can stay quiet, or I do damage?
here is the log requested. damn if I get spikes with the turbo!
so you tell me if they are close to death?! I hope not of course.
What is known now turbine rigetenata is up to 1800/2000giri if I throw everything down, it takes a lot to climb, then from 2000 it pulls a lot, or, if I step on the accelerator gradually, the salt gradually up to 2800/3000 rpm and then by a tug (I've seen that corresponds with the opening of the geometry, is this normal draw?
For the wg, I will quote half a lap behind as he was returning from the review, and try again a little!
But the strange thing it is, for example, I disconnected again the devimetro, and I've done two tests always pulling 3* from 1500 to 4000giri about (I was disappointed to go down to the limiter) and two times the peak was within 2.5.
At the mass air flow sensor attached, I pull those peaks? Because actually enter the air? Or because they measure less and then pump ofmore turbo?
Sorry for the many guesses.
For the setting, eh I don't have the equipment unfortunately! But it is interesting! I will try to study and maybe experiment on a turbine that has my mechanic, I love to learn.
Shortly I am attaching also the other two files, so tell me what you think.
now, however, I don't remember if even without the mass air flow sensor, I had a peak at 2.7 do I have to check the previous log.
notwithstanding that riposizionerò the rod of the geometry as a revision.
Shortening the rod (increases) pressure
by lengthening the rod (decrease) pressure
Guys it is a clarification! Given that I noticed this kind of vacuum, accelerating gradually up to 3000giri and for this reason increased a around the shaft of the geometry (and then adding pressure, even if, in reality, the peaks were always those), I have a doubt! It is not that the geometry is too closed? Thus in addition to return in the position of oartenza, I have to try to decrease still? It almost seems as the face is the stopper, and then with the opening of the geometry to 3000 rpm vent and that extra push! Instead of being linear!
Do you believe this is possible?
