The failure of Rail Bmw 320d edc17 177cv

[kingsnake]

Hi, I have a problem on a machine, I mapped a 320d 177cv, I made a map nice boost,but without touching pressile rail and limiters, and in the moment that I enter the 4 or 5th gear the car goes into recovery and in addition to the usual errors of luca stanca that do not give any trouble diagnosis I receive the error plausibilt? rail pressure.
The car is in the recovery of past 3500 rpm, I have to say that to 1600bar the injectors are open to 1000 uS, and 1800 to 950uS.
Not ? a catkin excessive as to go the high-pressure pump in gavitazione,and I ask you if you have had a similar problem and how you resolved it.

[tezzero]

based on the calculation of the ecu c'? the difference between the rail pressure ,the engine torque or other...please review the map and possibly delete all the dtc (? an ecu is very smart...)

[alfajtd]

without posting the file ? difficult to tell you where you are wrong...

[kingsnake]

You are right, but unfortunately I can not post the file.

[alfajtd]

then you have to do is rivedertela and resolve..

[kingsnake]

in the meantime, I want to do a test to the customer by connecting a pressure gauge fuel pressure near the fuel filter, to see if in full acceleration, the pressure drops, I have some doubt on the pump to the low pressure in the tank.

[frantik3]

connects a diagnosis and see all the values that you want
usually the car if you are not done with policy, take them immediately to the error

[kingsnake]

The map I have had to do to make it go fast, to test this, turn to the 2-bar fixed, and has downloaded 237cv to 3610 rpm and 48kg of torque, the problem ? during a test on the road as you insert the 5 goes in error, and it appears plausibilit? rail pressure, unfortunately this forum does not allow me to post the file since I am a newbie.

[franco75]

at least tell us if the map rail ? original and what you have changed, you said only the turbo 2bar

[kingsnake]

the rail ? the original, of course, I modified the torque limiters torque required in standard conditions and during acceleration,and ? very true to that read on the tour, I noticed that most riducevo the injection times, and later was faulty, same thing with the rail pressure, initially I had put to 1900 bar, after which? I have had to push to 1800, which would be the original value, the car with everything that goes on in the recovery, not a drop of smoke

[megamind]

The rail too high d? that type of problem, but no ? you have touched by mistake?

[ugoboss]

these cars are very sensitive you have torque limiters, as you have them increased.

[franco75]

probably in view of the flow controller of the pump ? forced to work in extreme conditions, and the control unit realizes that in order to maintain the pressure he's using the critical values. I think I have read somewhere, but I can't remember where and if the source was reliable, that these limits and the PID of the adjustment of the pressure are autoadattativi.

[kingsnake]

these cars are very sensitive you have torque limiters, as you have them increased.torque limiters maximum I leveled to 600 nm to turn them off

[angelolsp]

unfortunately this forum does not allow me to post the file since I am a newbie.
Not, you can download up to 80 messages, but you can post

[nox]

He tries to raise the rail pressure. However, as you said angel the file, you can post safely? the ori if nn and in the database, put it them ? then post only the link

[kingsnake]

[nox]

You have to go to fullscreen? advanced you'll see a small window with attach file, of course you have to zipparlo ,

[kingsnake]

Thank you, I upload it tonight now that I'm not at home

[pnausmotorsport]

you provatoad raise only the limiter of the rail?
pnaus

[kingsnake]

No, it would be useless I think, however, now the machine will go? from pompista, terr? updated if the problem ? the diesel

[angelolsp]

I believe ke and from the map!!!

[angelolsp]

you can not make a diagnosis in the movement and struggle-leadership in the parameters?

[kingsnake]

[angelolsp]

and see, keep us up to date ake xke not I have heard issues with the injectors on these

[kingsnake]

[kingsnake]

Status., the machine ? went to the pompista, and according to the customer there were impurities? in a filter if I have well understood ? a retina, before the pump, rail, now the car will not be in distress, and tomorrow I have to try to grease it and you do? know.

[kingsnake]

I tried with the diagnosis, and when I require diesel creates a difference in the loss of 200 bar of rail pressure, in practice, when the machine requires 1700 bar measured from diagnosis 1500 bar, and the machine goes into recovery.
This machine is equipped with 2 pumps of low pressure and we have to see if the problem is on the pump in the tank or under the chassis.

The diagnosis makes me visualize in addition to the pressure objective that measured another fuel pressure, which tends to be stable at around 220 bar in the time that it requires diesel drops to 160 bar and the machine promptly goes into recovery.

[angelolsp]

but you have not solved? as never before was not in recivery and now we are going again? just try to raise from the map?

[alfajtd]

if you put the original drive is doing the same thing?

[kingsnake]

but you have not solved? as never before was not in recivery and now we are going again? just try to raise from the map?
It is, in practice, as I try to increase the time of injection problem

[alfajtd]

then the error is in mapping.. as I understand..

[angelolsp]

it is, in fact, ankio, I believe...

[kingsnake]

[tezzero]

With the original map it works or not??

[kingsnake]

With the original map it works or not??
With the original map is not to be faulty, as not to be damaged with a map soft, the problem occurs only when I cross a certain threshold of opening the injection

or better injection time, even with the original rail pressure

[mirks]

Then you have solved it?

[kingsnake]

Then you have solved it?

No, I've reduced pressure and injection times and I've left to lose

[tecnoracing]

the car has a check on the manonissione of the couple, you should also find the diagnosis map wrong

[oakley1]

I confirm that that says topracing. the torque limiters how much have you given???

[tecnoracing]

this is not a problem of the limiter, but c? a few bits that controls torque, e-mail the file to the section ori and paste in the link that we can give you a hand

[tranky]

Hi to all,
I open this post a little dated because I got a bmw 320D E92 177cv edc17 already mapped and the customer complains about the anomalies..
in practice, the drive switches off in the race and in diagnosis reports error to ecu.. I have documented and I have seen that this error is inherent limiters in the map that demarcate the torque (nm) with valoire GOLD and raising the limiters well-known, and aligning the pedal, this pair remains "limited" and the ecu behaves strangely giving error ECU diagnosis.
I did a test by putting the file ori and in fact does not presents the problem by pulling it and putting it under stress at low revs making the request on pedal to the metal, while with the mod, in random mode, the car died..
From various information found on the web I came to two areas that are 0584c6-0584d0 and 058548-058552 default imported 3277 and brought now to 5000.
Can you tell me if there are other limiters for this ecu to work around the problem of the couple and if they are just the two limiters found?
I do not ask for the solution to the jelly is ready, but only indications of where to find and how to move to remedy the problem.
I attach both files, ORI found on the net that the mod that I found that is loaded on the drive.
I tried to make a map from scratch before finding those two limiters, but the problem persists, I don't know if they are the only ones or are there others to unlock..
Currently the car runs with map soft with the pedal to 400nm, and seems not to give problems by changing those two limiters.
Thanks to those who wanted to give me a hand..

[ugoboss]

hello tranky, I found myself in a prablematica similar, and I had to reduce the limiters and other things to work around this problem, I know these ecu have the tourque monitoring or something similar that controls everything, I also know that there are sw that the exclude (type *******) unfortunately I don't have nothing to help you but I looked at the areas you marked, but it seems to me that they are a completely different thing, I can inform you and then tell you.

[ugoboss]

I was obscured the name of the sw, in any case, it is one of the most well-known to exclude the management of fap ,egr, and various things, the areas you reported I as limiter speed compared to the engine temperature, then I don't know if it limits the power.

[tranky]

In the meantime, thanks for your interest.. those areas that I have described I have identified from various discussions with a minimum of photo views around, and the two areas would seem to them that give that problem, and that there are other, the torque limiter.. I am going to sieve the file but I can't find much to faith or any test.. it is very confusing the issue of the torque limiter..

[ugoboss]

then I made a few phone calls and friends you are made to feel, they told me to put to zero by 0438a0 -to - 043bc0 and raise at FF 043bd0 -to - 043c10, and try, this seen on the file ori 2 mega, see if you can make some tests, I in this moment I do not have the means available, hello.

[tranky]

I attach photos of the areas found in the net for a comparison

[ugoboss]

if you have the machine available to make the tests and see ;-)

[tranky]

let's say that I have the opportunity to write it a couple of times before the owner to pass over me in reverse..
Now I try with those curves, and I'm trying to identify that near the limiter on the file that I have, is not exactly equal then I am to locate..

[munro]

The edc17 BMW individual bits, torque limiter... as well as a variety of other limiters.. scattered all over the file...
The roads are two or eliminate all the limitations with the help of damos..
Or make a map deceived that works on tinj, and the rail..
Even on the times there are bit of limitation..
However, for standard maps the second solution,even if not very refined,and preferable..

[munro]

I forgot... be careful not to overdo it with the times and turbo if you want to fool the ecu because in reality it is not deceiving at all..
As said Ugo, there are ecu maps, torque monitoring monitoring as a function of the amount of time the motor takes to reach the required torque is the actual how much torque the engine is putting out..
It is a bit complex as speech but as a controller of the driving torque on the torque...

you can know what are default set these individual bits around?
anyway I will keep you updated as soon as I load the map

[munro]

On the last 118d that I made were set to 320nm..
However, it is enough to see in the diagnosis to how much torque you restrict the making and then look for the value in the file..

the map is made.. I found the various limiters and I have made gains from 85mm3 at 460nm (as from the translation of the ori) and the car goes.. slow but like.. the automatic transmission is really slow..
Anyway now the car is in the test and see if still the problem!
thanks friend

[Alfiuccio]

matthew, there you help understand where is the map conversion? I also have a problem with a bmw (f20) 116d with error plausibilita' rail pressure (rail pressure ori).....

[msport (exil77grande)]

I attach photos of the areas found in the net for a comparison

as it is written by ugoboss the two areas you mentioned are as much of a SPEED LIMITER VIA the TEMP (ENGINE SPEED) and then the screen found in the network are not accurate for the rest I think that with the 2 areas indicated by ugoboss you should already resolve even if there are other areas.

I found the other areas and changed the couple. No more failure in fact. The car is up to 500nm of the pedal and it goes quiet.
Thanks for the info

perfect I'm glad that you fixed it and if you find it useful my help I'm more happy.
