change advances

[ecuboost]

thanks, always useful

[dvdtuning]

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

here's to you guys, as promised....and I have to say that this is not a guide to real own on how and where to intervene to moddare this parameter, but as you will read, it is a series of observations to try to understand this complex parameter of the diesel engine...

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..

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 are always number 1 ciccio!!!!

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?

[Chris156]

I am reading the file on advances... I think that what ? written said I in a few words in various posts I have written!!!

[cicciogsr]

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..

[franco75]

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?

[cicciogsr]

on the fiat group's cr should be elm327 and edf to do a complete log
