Hi guys and the few that use titanium and are inexperienced, I bought a alfa 19multijet 150 hp
And I discovered that it was already mapped and evil besides
Practically had lifted the values of the turbo without
Touch the limiters have increased 150 points
And the machine mi fails when it sank l throttle
Then I got up to 150 points for the limiter, but fails the same less but the same
What should I do??
Thanks to all
Alex
prepare a map ori the write try the machine and see if in the meantime it's fine . you have to go by logic, not by trial hello
With the gold goes well with my doubt and when I lift up the parameters of the turbo-150 points how much points I have to raise the limiter??
But before seeing the map or not map, because you have not made a diagnosis to see if the breakdown of that is on the turbo pressure? could it be another thing? with the map ori should not be in recovery because he has a request that is different from the modified map, it is normal, but should be fine with the change if the stain is applied.
It is, in fact, I have done the diagnosis and I know turbo pressure low
Place that, as he says rightly egs, it should be made a diagnosis in order to understand if the problem is that the failure is the pressure of the turbo, it would also be helpful to understand which version of the 1.9 jtd have. It is a 147 €3 with ecu is EDC16c8 or €4 with EDC16C39?
Given also that I am a user principiantissimo I advise you to take everything with pliers, what I will say and maybe wait for a confirmation or a denial from some experienced user.
In the case of edc16c8, the original map of the 150 Hp seems to me to have to 4000 rpm and for 70mm3 of fuel pressure, turbo 2330 which is also the expected maximum value in the map turbo, then in the version of the mod if it is increased to 150 points, the pressure should be 2480.
The maps of the turbo should be 3 addresses 0F82DA,0F851E,0F8762 and are all 3 identical, then there is a map to the address 0F89E8 which is full of 2400 which I think is a restrictor in the turbo pressure as a function of the external atmospheric pressure and I believe that if this was not adequate, obviously, as they exceeded the 2400 would give an average and I think there's another bit that is located just after the map to the turbo that limits the pressure and also this should be changed to a value that is obviously superior to the 2480.
Then the machine and euro 4
And error and p0237 pression low
Are inexperienced I use titanium I have increased the turbo pressure of 150 points and also the voice limiter turbo I have increased 150 my doubt and it is not that the machine when the pressure peaks should be even more on the pressure and maybe I have to raise more the limiter? ?
Because if not fo rapid decompression should not be in recovery
According to me, it is possible that there is a peak of pressure that goes beyond the limit, and probably raising more the limiter, the problem disappears, but I seguirei in a different way, or will a little bit the management of the variable geometry making it open just a bit more to do to reach peaks so high pressure.Quote:

I repeat, however, take everything with pliers, because they are not very expert, wait for advice from those who know more.
I I were you I'd post your modified map and the ori, here there are so many users that are experts and would give us a eye on it and advise you for the best
pression low= low pressure...Quote:

Hello an overboost you're right and the problem then what could it be??
take a spin on the street and tell me the pressures in the turbo between the lens and being measured as arriving
That is,??objective and measured?
I don't have the gauges mounted!!
You need a diagnostic tool
Will fit the maxi-scan 509???
I have that!!!
We can hear the phone so I give you the parameters as soon as the arrival in the country???
From regulation are prohibited in the private contacts. Take a picture and upload it on the forum
Raga hello give me a tip, I replaced the map to the machine, and now it's fine apart from the usual error p0237 I noticed that the old master has removed the swirl, however, do not have tapped holes zi just put the caps of the first that I noticed that the bleed could this be the problem??
I am aware of the swirl if you do not disassemble the manifold it is difficult to see if there are or not because they are on the inside. From the outside you can only see if they have dropped the shaft of the motor and have it locked open. Open holes in the manifold, there should be that's for sure
Hi guys, I'm autocostruendo a down pipe for my alpha could you help me
I need to know the pitch of the nut welded to the down pipe where zi mount the lambda
Thanks
Alex
For the problem of the turbo: you have also given fuel?
Because if you increase the increase in quantity of hair, even the pressure
so it is possible that the
mine goes into recovery x the pressure that comes with 1.8 around the limit and set it to 2650..
I think you're doing something wrong.... 1 where read the value 1.8?Quote:

then to 2650're more low and go into recovery fixed. 3 if you have turbine series 1.8 bar are too many. 4 your post is incomplete and too generic. Provide more data or attach a map to better understand
I read it from the time of diagnosis, as soon as I go to full load, the pressure rises to 1.8
And in maps turbo as you are how to max value? If you are below the 2650 may be that you do not follow the.pressure goal, maybe you have the.geometry.variable.blockedQuote:

Hi all, every now and then by reading and acculturandomi in the forum, I find curiosity and wonder.
Just above I read that the pressure of 2600 mbar approximately are inclusive of 1000 mbar of atmospheric pressure, then in theory the turbine is working at 1600 mbar about right?
So if I, with my alfa 147 150cv 16v that sometimes, I have recorded "peaks" of 2600/2700 mbar obviously, only with the 2* and 3* maecia you permission settings, if I press at the bottom, is this normal? Can I stay quiet? I know that from the original map, the limit is 2330 mbar if I'm not mistaken. And I have regenerated the turbine by little, I would like to destroy right now!
Thanks and see you soon.
I would stop at 1.5 barQuote:

There is something that does not go according to you?
Go back at least half a turn then, even if the best thing would be to know (I can't remember) that the turbine mounts and check in the technical data sheets that peaks bears.Quote:

I'll explain more in detail the speech the actuator, in practice, I have regenerated the turbine, but the car was not responsive, so with the mechanic we tried to make a turn of the screw, and even seemed perfect, so we tried to make another one, and felt too the breath of the turbine, guindi we went back half a turn (total a firo and a half more), I have used it so for a few days, I've done several measurements with multiecuscan and, of course, misuravo peaks of 2,6 rarely 2,7 when press pedal to the bottom, this to the low gears for the 4* then she squirts so high, then my fear of doing harm, we ripostata in the starting position, and was so until an hour ago, and still in the trials of these days I recorded these peaks with those same values, only that the car is meko reactive under 1800 rpm, so today we have given back only a half turn of the screw in order not to overdo it and to call.
Even when we tried to increase those rides did not go over the values, somo more or less always the same, for the precise model of turbine I inform, perhaps the next time step from the mechanic I make it look, or if I find certain information in the network.
My question is, given that even trying to increase it to a round and a half more adjustment of the actuator geometry, the peak values are increased or decreased, it is only changed the response of the car, according to you, is it normal? Now with just a half turn of the screw more than the setting that I had made a review can I be quiet? For now no map, only the egr off.
A greeting to all.
Sorry for the dopoio post, but I could not edit the previous one in the net I found this on the turbine, it should be her.

Hello MCDJ90, the geometry does not need to adjust it with the dipstick, but from the map if no is a hut that you do not exit more.
Hello PasqualeGt there is a table/graph for the geometry a bit as that of the turbine in order to insert values that seem reasonable in the map?
In fact, would interest me too!
But it is possible that the geometry is influenced by the swirl? To me have removed physically, but I still have the actuator, and the map manager (which I hope to turn off soon), and I notice that the trend of the pressure rises first up to a peak of 1.6/1.8 for then decline after 2800/3000giri, when you feel the urge from the engine, but the first is slightly dead!
If it changes a little bit, abolishing the management swirl would be a good thing!
I honestly I have the 140 hp in my case, I do not have the swirl
I want to know more about the features of the geometry because it is it which makes the passage of air to the turbine decidendone the rate of rotation so that the greater pressure of the suction air .that said I wanted to know the characteristics of the geometry as a map .
But the part to replace it, there is no way to test the operation of the valve pierburg? I asked my mechanic, but he says that solotamente not break, the next time we put it on the lift, I also check the tubes, maybe.
Unfortunately, these seirl as I understand are really dangerous and I there are the past.
As soon as I have to redo the deployment, I replace my manifold with the aluminum of the engine as your own! Without swirl.
For this I wanted to know how to turn them off completely and then see if you can intervene on vestione pressure and geometry, recuperarci a little bit at low rpm.

there sure is. does it also mes.Quote:

I've got the mes and elm327, if you tell me how I can try to see if it works properly, if I have to do a chart with some values, I've done some, but I don't know if I put the right sensors, I had taken the pressure measured, pressure lens, throttle valve and an overboost, but I don't think I have done well.
Could you advise me?
Mes 3.5 calls him so: Bost control/solenoid.......anyway....*****and I see it, if you have changed the turbine geometry is clean(not blocked) then you will not have adjusted well to the rod of the geometry. You probably have not picked up the references when they did the replacement.
If you take the log of the pressure target and the measured one, and that goal is to the most high it will give you the error p0237. Then or have a pipe that vents, or you have the rod adjusted wrong.
