hi all, I ask this wonderful question.according to you ? it is appropriate to amend the advances on a map with normal editing?let's talk about advances that are not too exaggerated.
I sincerely change them wrapped a grade one and a half when I exaggerate with the diesel for? I don't know if something as reliable as a modification to
From my point of view on standard maps do not need to complicate your life and it is not expedient to change completely advances.Quote:

on standard maps, I will not touch them ever,you don't need me
if we are talking about an engine processed even if ? diesel where you seek performance and not reliability? I agree to change advances, but in a car with standard maps, and with normal use, as they say, above our friends is not worth
it is not convenient to edit them, here's what I want to say x is not worth it. and a way of saying sicilian hahhhhaaQuote:

if we are talking about engines with combustion x 1/2 spark i.e. gasoline, alcohol, etc., according to me, are worth the time, but in diesel engines with the exception of some 2-stroke, no!..but I could also be wrong:
the advance of the flow is used to optimize the combustion itself, anticipating the flow of oil to the chamber or pre-chamber combustion whenever the engine increases in rpm, cos? that the diesel fuel to burn before the piston reaches TDC (top dead point) where the performance ? almost zero, why? in the diesel engine ? the piston to ignite the fuel by compressing
I hope I was clear.
In common rail systems to increase the advance according to me ? less incisive why? one of the nuances? of the system ? to increase the pressure and cc of diesel within the same injection time..while in the older systems it was necessary to increase the stroke of the slider controls, which consequently delayed the injection..correct me if I've done something wrong...
All true what you say...but your question goes beyond the garden!!!,for now unfortunately I can not cover for me to be an engineer..for sure I can say that in the diesel of this and the past generation that you can't? overdo it with the advance..arise many challenges given by the mechanical structure of the engine
I know the diesel engine, shelter mainly injection systems diesel of old and new generation for more than 20 years what you say in part is fine but between the theory and the practice, how do you know there goes.*****s, you can always have fun if you have the time to make maps with advances and important test, if you notice that the motor draws significant benefits places the files and we work on it all together for them..
I don't seem to be uncivil or rude...advice: avoid the parentheses...
I think it is useless to specify basic concepts...all qu? no problem!!
munro I think like you... in the cr and pd, I prefer working on advances pi? that increase significantly the prex turbo x! but as in every job, each has its own method
Also, according to me, better not to touch them, if you calculate bad the exhaust gas temperatures rise too much, and you ricshia.
Let us remember that x will? manufacturers want x nn be too much competition in both the x back in to some of the regulations the car, leave management software, coarse and nn optimal, or better, with parameters below the actual potential? also x as confirmed by other users. In my case I do applications big turbo and only significantly changing some of the maps I can have response times similar to the original, taking x as the turbolag delays few or non-existent.
I ask a question on a vehicle where it is ? decided to take a strong increase in performance you would prefer to work on pressure turbo or advances, and pressures?
I fully agree with you..Quote:

moreover, the idea that to inject too much out of the pms serves nothing and ? deleterious.
in my small way, I have learned that every car ? a story ,
in parit? version I happened to have diversity? ,
for wear and tear or parts poor/economic replaced over time
it leads you to behave accordingly in mapping
ori or the mod that is the car if you need to anticipate the injection
it is anticipated :)
since there are opinions controstanti on the change of the advances, I pray all to say your thinking about specifying the reasons, perhaps using examples technical or practical examples!!!
So let's see if you**** these popular rumor.
I say I supermegaprincipiante, I would increase in an engine is that ? a bit knackered and chilometrato, I would leave them instead of the original in a new engine
Great munro, appearance, anxious to read your guide... :)Quote:

thanks, always useful
thanks munro, I read it all and I have to say that ? an excellent guide.
You talked about more? times of the ignition, but I don't understand if you want every single cycle of the piston, or the engine?
What I learned by reading the info and seeing many maps ? the advance (especially in the mjet 150 hp), which is incremented in fixed mode, high-load and instead in the old jtd 115 is given gradually with the increase of rpm.
I wanted to know if ? a way to correct, and why
hi sorry I did not understand well the things that what does it mean to transform the isentropic?... if it produces heat during the compression ? certainly a transformation of the ideal, but with dissipation, and then not ? some isentropic..... I don't want to continue to emphasize that this report documents translated into English are difficult to understand from all claims little true...and anyway, at the end ? 't understand how to change the angle of start of injection( this ? the exact wording of the advance in the diesel engine), I don't want to make too much simple... known as the iq that vuooi inject you with calculations, how far in advance we want to center the phase profit of combustion to be there? you need a series of experimental measurements of the function with the map ori of the car... and in any case, if you inject out-of-phase useful to limit the post-combustion can have advantages in the transient increase of the speed? emptying of the combustion chamber..Quote:

make a log of iq and advance with the map ori, and detects the values after we see how to modify once you have increased the port diesel... if you don't change your attitude not esporr? own nothing I am not a teacher but only a fan like you..
You're always the number 1 ciccio!!!! ;)Quote:

It is a perfect ignorant as they are, it would be necessary to distinguish two things:
1. Management of the advance, in general, for any diesel engine, excluding the CR with multiple injections
2. The timing of the multiiniezioni in general, and CR
It would be necessary, according to me, before addressing the topic, describe how you are managing multiiniezioni, or know the various quantities, the timing, and how they are related to one another.
I have a couple of questions,
According to you, the postiniezione can affect the preiniezione?
When you speak of advance you are referring to the one of the preiniezione or main?
I am reading the file on advances... I think that what ? written said I in a few words in various posts I have written!!!
but from that document, it is understood only the reasons not to change them but not how to modify them and explain how to calculate the duration of injection in degrees, but does not explain practically how to do it and honestly seeing the attitude a little constructive of some users, I say to you with many frankness, that if you post a log of a 4-stroke engine with spontaneous ignition of the dar? gladly, the eye of the pi? not to make?.. the document you if you can understand it I'm here to read your explanations why? for me says it all and nothing..
ciccio if you tell me what it takes to make the log I will soon gladly.
I have a elm327 bluetooth, a tablet with full torque.
Are enough or I need something more professional?
on the fiat group's cr should be elm327 and edf to do a complete log
? what I was explaining the other day... what do you not understand? I have come to read the met?.. I would not say not to touch them, in fact.... it seems that he wrote it myself..even if there are some things without sense, but it will be? the fault of the translation..Quote:

In case explains the importance of the advances and changes that must adapt to the other parameters. Explain the principles of fuel injection and the operation, when and where to inject, etc.
Usually in the moddarli will be adjusted based on how much fuel you require?
I understand perfectly what c'? written but not d? a policy certain to change and does not distinguish between the various injections.. I am not the mod of advances for maps that do not exceed a certain range, and I have done all the necessary tests and I can say that if advances too, as you only have exhaust manifolds glowing and nervousness due to too much compression do you have a car that top seems to stop.. the old jtd does not love to have injected diesel too soon, because? you may scompensare the pre-injection and the right moment to enter the field and the main at full load... if I say instead that the advance payments should be touched on maps thrusts to help inject large quantities? of fuel by the physical limits of the stress that you download on aorgani mechanical, I'd agree, and you always have to compensate for the advances of the various injections...
on the basis of the fuel actually injectedQuote:

I vorei understand why ? been added to the conclusion at the end..it has nothing to do with all the explanation.. and I have to say that if you have a smattering advanced of this world will understand easily there? who wants to say..they are perfectly consistent with what I say..
Ciccio do you remember the example I made of a diesel aspirated? it perfectly follows the dynamic logic of loading the fuel and the ignition.
ok then explain to me the strategy of injection of a cr edc16 between pre-main and post injections how would you chamfering the injection, consistent with acceptable pressures and temperatures that do not affect the volumetric efficiency of the engine... reading that document, I have asked myself many questions.. for me we take into account a few variables.. on the diesel you can afford many approximations, but not ? said that make it good..
the problem ? the pressure inside the cylinder.. and no.. :rolleyes:
the boys and I refer to munro (even if the guy is not heeh) and cicciogsr I kindly ask you not to create any friction between you that then you perquote in the various post because it's not the first time that it happens,munro, you need to understand that ciccio studies and maybe some of the things he sees differently if I believe that wrapped writes in a manner a little too presauntuosa and definitely does not have your experience in the field . ciccio you must understand that munro is doing its best to make a contribution to the forum by sharing what they know, or think they know, or that is on the web ne + ne - indeed, I believe, is to be admired,for the rest of this attitude on this forum do not want to see otherwise apart from this that it is a reference only written beginning with the infringements, and if you continue with the ban,here writes and discusses serenely who knows or believes to know can write without superiority and no obligation and anyone who thinks otherwise can do this,you just have to think that I learn from those who do not even know what a mapping and vice versa,it only takes humility,I hope the speech is clear for both and anyway, I noticed that munro which mature person that it has already deleted the post where he intervened in a manner not adequate sign of having understood
:) I fully agree, but I know jack and ? a good guy..Quote:
