View The Full Version : Pressure turbo Audi A3
Hello to all
I came across an Audi A3 2000Tdi
140Cv 2006 with 150000km with series motor BKD...
This machine has already? changed the turbo xch? you ? locked the geometry and broke.
Wishing map we thought we'd put a pressure gauge on the turbo x keep it under control.
According to you, v? a pressure gauge 30 ? or should I look for something more?
Professional?
Thanks
depends on what you want to do with the machine body section..I use the gauges of the crown and diesel are excellent reading range up to 3.5 bar
if you want to be quiet.. from 150 points to the pressure turbo.. and you're not in place
if you have to do a thing soft ancche 100 points is enough
150 points is too many? also I have that car and I impostatao the maximum value of 1.5 bar to burn 65 mg of diesel fuel by adjusting obviously all the maps without tricking the ecu..should be a gt1749vb that, according to me, at 1.5 bar peak should not be too exploited..
Today I tried the gauge with the map's gold and reached the maximum at 1.4/1.5 bar
Then I tried to give 120 points to the turbo outlet
To my amazement, while I pulled the gears, the pressure area at 2 bar, and then down to 1.6
But ? normal or ? abnormal?
0cchio ste turbines are immediately on the botto!!!!!
I give you advice start to map it without touching the map turbo then if you need the increments , ste turbines are m** * * * from you spezzno posts as fruscelli
are turbines fragile... but anyway to squirt in 2 you have toccatp time? abbasa the map of the geometry in the point to where you have the peak
on that turbo more? of 100/120 points I I wouldn't go as ? too delicate... even why? raise it too is not needed according to me, you do not walk alone pressure
and easy to calculate fuel injection and air. the mixing ratio ? of 14: 1
a TDI 2000cc has 500cc in each piston (cc air)---. 500/14 ? 35 ...then pu? work with 35mg/strk fuel and turbo 2 bar. if mettemo dual air we need to double the injection of almost 70mg / strk.
we must try to keep the most? air, fuel or a perfect mix
I have not touched the geometry
And press the turbo I have given only 120 points
Tomorrow place the map I made and if you kindly give me an opinion or an explanation of the xch? I have this peak at 2 bar.
That really is? I on the gauge, but if you attack the diagnosis of T*****4 me detects a maximum pressure of 1.62
I do not understand this discrepancy between the reading sensor turbo and the pressure gauge that I put....

I ? clear the formula of the ratio between air and fuel but not the relationship with the pressure of the turbo...
the difference, and the atmospheric pressure where you live...I think I do 0,8-0,9 bar
Eye that the bkd have the turbine, a beautiful potted and gi? his warms.. The 100 points are usually enough and advance to a good mod..
Betrescudan Sorry I explained it badly
I meant to say the relationship between the air/fuel mixture (14:1) and pressure to add to the turbo .
Or are the two things that are not connected to the turbo pressure and the mixture to a/c ?
What do you mean fil89 with the fact that the turbine beautiful inbucata? That are already? to the limit.?
Thanks
The bkd has the turbine is mounted in the rear of the engine, exactly between the wall assembly and the engine block.
His position does not facilitate the cooling, and gi? the original some golf with that engine tranciavano the post.
For this ? recommend that you do not overdo it with the turbine pressure.. let's Say that with 100 points in the turbine and working on durations and advances you get good results from that engine, without esasperarlo.
Also counts, and that if you speak of a turbine is easily accessible, can you? "dare" with pressures pi? high, and the day breaks (I do the example of my machine) in 1 hour and a half to change it and you are affixed.. Them you have to disassemble half the car to get there.
perhaps anticipating the changing oil and doing a good cool-down, can you? "dab" the decrease of the reliability?.. For? here, it's better not wanting too much, also has the flywheel (dual mass) as a point "delicate".
? always a pleasure to travel on the forums!!!!
Thank you for the explanations
place the map that I had done before doing the course
give me an opinion?
it seems to me that you have not touched the geometry
the only thing that I think is the press turbo.
it seems to me the right just a nice 30/40 points higher than you should, unless they have touched other values of any of the limiter out of the driver, which may limit the pressure (I speak from a beginner)
give me an opinion?
thanks

my friend,I think that all of those with whom you spoke up now receive the same message when I want to see your map

that ca..or this?...and a forum ******?....I want to learn....I want to be useful with something....and I can't....HEY ADMIN...you have a user here or you see that slowly-slowly they all go away?
I'm sorry
If ? my fault x my negligence, I apologize.
Having seen the other post I thought you could do
but read the rules there is that difficult? in order to download you must have a minimum of 80 messages in this forum does a lot of the throat of the database, and so if you want to download you have to be active and contribute to the growth, usually those who lament this limitation of 80 messages are of the hit-and-run
I'm sorry
If ? my fault x my negligence, I apologize.
Having seen the other post I thought you could do
you can? do post the map to ask for an opinion, probably the user betrescudan has not read the rules
Ok thanks
If someone kindly I can? to give an opinion I would be grateful :-)

Problem solved
The turbine, which had just been replaced, she was the cause.
In fact, the machine smoked a lot of white just ? been replaced.
We washed the discharge and continued to smoke... in Addition to having the usual problem of that strange peak pressure
We thought that was the residual oil was a trafilaggio of oil from the turbine.
We decided to risostituirla.
Now ? all regular and smokes zero.
Seguir? the board of map without touching the pressure.
Also xch? to be thorough I did make a map from a Master, and when I examined had as many as 160 points on the turbo pressure and the same on the limiter.
And from the course that I did recently, which is confirmed by your post, it is clear that these models bkd better not to go beyond the 120...
Thanks to all x the availability
To say that 120 points are sufficient, or are the few, it seems to me hardly accurate, and I think that nobody can say that the increase to give and not to quantify the quantity of air that you want to put in the room to burn diesel then give less points, but if you are incremented in a wrong way tables angle
Of injection the pressure rises without control, if, however, adapt the maps of the turbo to the iq that you want to reach diagnosis, you will find there? that you set in the map.. for example, I have 65 mg of diesel fuel, I set the pressure of 1.55 bar and I have given the required points only to a certain iq and not on tuttonil operating range.. And make quietly beautiful horses without smoke, and without compromising the turbo
Six by 120 points and increases without policy the diesel .. Or giving percentages without logic the turbine the watercooler the same.. What I want to say ? not to focus on the points that you think keep you safe..
You are absolutely right.
But I unfortunately I can base it only on what finorau I know.
Are newbie and st? trying to learn by doing sleepless nights sifting through the various posts to try to understand and learn more?.
I ask you too if you tell me what criteria I can calculate precisely the amount of air flow in the room?
And as to adapt the map of the turbo to the that I want to achieve?
For injection angle you mean the advance?
Thanks
In regard to your questions, you can read all the post in which you ? spoke of the logic of change by informing l ecu .. Being a pd the duration are expressed in degrees and not in ms as in the cr .. The flow rate that you need decide based on the diesel you want to burn ? all a matter of afr you have to delve into the functioning of the maps that limit the diesel maf and map to decide how much diesel to burn in and adjust everything accordingly.. Or request limitations on the duration of injection and the turbo to the air ? essential not to v? neglected .. I can recommend to do tests and check all the parameters with the vag

Sorry again but they are still poor in terms
And not find them so? abbreviated
What ? a pd ?
What ? the cr?
pd= pump injector
cr= common rail
considering that this is a very fair response
