hello to all.
place this screen that identifies the map advance or start injection of a 2.0 tdi
how do you interpret the changes on this map.
there are 10 maps any more... and should be based on the water temperature, you change usually the last, with temperatures more water.
but the values of the last position breakpoint as a correlate with the diesel...?
who knows something about it?
no one knows how many degrees you can be daring on this engine? from the original ? very delayed 20?btdc to 4000giri
btdc st? for before top dead centre,i.e. before top dead center...then 20?degrees before top dead center then and early 20? at 4000 rpm...
But not before ? before? Mmmm
sure we all said the same thing. early 20? before top dead center. the injection is' them'.
delayed in the sense compared to other tdi as the 130 that I seem to have 2 - 3 degrees in always to 4000 rpm.
if you take the bad trend of the thread that I opened I..I think your questions difficult to get answers....I still I keep my eyes and leorecchie wide open...have you ever seen someone decides to reveal things that do not want to hold only if....
we hope that the forum will become one of the few where you say things publicly.
however, the advance curves SOI on that engine are the ones, those that have more experience know the limit where you can push and to improve the erogazione. if you overdo co the advance they do damage.
the written l?..in this car if the advance payments, the soi will also increase the total duration of the injected...then inject more fuel....
Guys sorry, I misread obviously.
In any case, we are talking about a 2.0 in that the cavalry?
That said, I don't know how you can/will help, I don't have the slightest experience again.
are you sure?
to equal the duration of injection, if the increase in the soi, the beginning of the first, but the duration ? the same.
example 34?duration 25?soi = 9eoi end of injection
34?duration 27?soi= 7eoi
if you say so...
I other information I know ? so.
I tried to vary slightly the soi, well, vag, you are raised, but the duration in degrees ? remained the same.
I say to you that you always read the same values of duration why? in the ecu that value ? set....in this car, unlike the CR, the duration of injection, I believe that "does not translate fully"..if by 24? soi steps 27? the duration automatically aumente of 3? and the eoi remains unchanged because the ecu uses the maps to duration just to know when to close the injector..
then I can also be wrong for? ehh....
I'm not sure that there is the channel of the end of injection.
however, as I saw who had problems of smoking on the tdi or high egt for very long durations, anticipating addresses, thus causing the smoke and lowering egt, if as you say the duration would remain unchanged, at the end it would make no sense to increase the duration, because anticipating the injection already become longer.
however, if it comes to someone that confirms or denies only that, we raised a nice question.
if the duration dependent on the soi would be all the more simple....I just hope it is as you say...and the fact that c'? something that I did not go back..because e.g. the duration of have many times of the values in the negative..type -9? or -11?...and I can't seem to understand the meaning...
I know that the soi are used, depending on the temp. water. a warm engine is used in the ninth or tenth map soi cio? the last.
the duration depends on soi, water temperature average low is read a soi with advance less at low rpm to protect the engine and respectively a duration with values smaller that is, the 5 and the 4.
the duration is read from 5 to 1, the more increases the advance for more, you should read the maps in this sense 4 3 2 1 0.
regarding the first: I noticed now carry 2 data from log: 3234giri 16.7?soi 32.1?duration 68.1 mg quantity injected.
3339giri 17.7?soi 32.6?duration 68.6 mg quantity injected.
if by 16.7? step to 17.7? with practically the same duration of 32.1?- 32.6? already had to increase the amount injected. and instead, it only increases 0.5 mg
both the soi that the duration are selected by the appropriate maps...
I have thought about that long too, but have not yet managed to give me an explanation of these negative values: I don't understand the real operation... :confused:Quote:

Just for clarity, to better understand what we're talking about... :)
Can I ask you how many degrees you have increased the values of the Soi and duration? :)
You have already? tried these changes? Smokes a lot?
duration 4 - 5 degrees, and soi 3 degrees.
4000 rpm, 37?duration and soi 24,5?
Can I ask you on what basis did you choose these values? :)Quote:

with a diagnosis in hand and test x to see the improvements...
And are in constant development, is not definitive data..
I fully agree with you for an account and' the theory an account and' the practice,in this way you can actually see the changes.Quote:

the car in question ? the same, and the evidence we do together. and I rsteam,Quote:

if I want to inject 70mg have a certain duration if I want to inject 80mg another. the advance, you have to give, otherwise you get a fine in place very long after the top dead point that generates smoke, over-temperature exhaust the most high.
Until inject a little even need to touch the advance.
then it depends on the engine to the engine, this has less bass than the other 1.9 of equal or superior powers and increasing it at low gains a lot of strength. then at high rpm, you must be careful not to give too much otherwise the walls.
murano why? more than a tot, and still there ? a way to not make the wall not just the advances also out driver
vabe over 5000 do not pretend. but anyway, I set the limiter that shoots at 4650 and just and forward to them arriving pushing.
if you give as much advance at high you have to give also a diesel, otherwise it is a drop in the duration and the advance remains what ?.
you can have a hint of the mod out of the driver?, at least what it is about... even to the far right to think a bit.
OPS! I had missed this particular...Quote:

I don't know what to do'? the limit,
the people who did a lot of experiments, and broke something in the will. but for the advance, I stop as I saw the bed, and was recommended by someone. then if someone intervenes, which has more experience on the tdi ? better. also know what? the limit of the duration of the injection I would be interested to know with the injectors 550cc it seems to me that to mount the 1.9 and the 2.0 tdi. c'? those who stop just as soon as see a little smoke but ? an empirical test.
the injectors, if anything, bring the outside 55mg.....and from your duration declared that are 37? and that, according to my calculations correspond to more than 77mg of diesel fuel does not add up.....over all, from your log, inject, or 68.6 mg..I wonder....where the error??
if the limit of flow rate injectors and 55mg but from the log, and duration have all other things such as iq....c'? something that escapes me....
I know better than that. 2.0 tdi has the injectors so you call 465cc 6 holes while the 1.9 tdi 150cv has 550cc 5 holes.
but how do you calculate the diameter of the injectors, and the mg?
Those plus are usually boiso783 etc.. but the number if it refers to other things, sec. me. I have no idea.
and still 55 mg delivers them from the ori in fact delivers more, I do not think ? the range, why? I know that you can also inject 80 mg etc
I just wanted to know the limit and the duration of injection that you can push on this engine with smoke.
The solution would thermocouple serious at the exhaust manifold before the turbo, that way you do some tests and we will get you to the limit of temperatures over which the stop with the diesel.
I say unto you, that can't be cc...starting from the line of reasoning is very simple...if, for example, the 1.9 tdi and 1897cc of cilidrata total and dividing these cc 4-cylinder will have a unit capacity of 474cc,,ok?? if the injector puts out more cc diesel engine displacement, according to you and plausible??
the number in the injectors and reported to the mg that puts out..e.g the bosio 520 damage 52mg the 783 damage 78,3 mg and so on....
so now the "problem" ? if you are informed that the injectors ori's put out a given amount? how does the ecu calculate an iq higher than the flow rate of the injector??to make it simple if I have a faucet that gives me 10 litres of water per second as the maximum flow as I can get more flow from this faucet??
I just wanted to point out that it is possible to compare the dc of a petrol injector, for example by 440cc/min because that amount? v? divided in a minute...for the injectors diesel fuel, which generally speaks of mg/stroke..so what ? impossible to say which give 550cc/race fuel..equivarebbe to say that the injector's?tura completely the unit capacity of the 1.9 tdi, our case...
precisely cc/minute, I think of that ? the same thing on the diesel injectors, ? only a unit of measurement as a reference. In all the other posts that I have seen, and in other places they always talk about the 550cc. I never said that damage 550cc / travel.
maybe you don't want to understand..for the diesel injectors they always talk about the iq/race...if you say that bring the outside 550cc automatically understood to refer to each cycle-race....the which ? virtually impossible to...on the forum I posted a table for the injectors and related course...well these are I in mm3 or mg ? not in dc....
yes, but I repeat that I never talked about 550cc/travel.
hey, anyway, the injectors are a little off topic, in my ingnoranza call them 550 or 465 ? enough, without cc.
but if the stroke of the 2.0 tdi ? of 95.5 mm and 35? of duration (which indicates the degrees of the motor shaft as it stays open the injector ) is already inept 67-68mg; not ? correct to say that the 550 damage 55mg/travel. I think they give more even the diagnosis tells me.
