Nomenclature maps

[bart]

I would like to start a new thread dedicated to the study of the individual plans of the maps and their axes, which could be useful to beginners and anyone who wants to deepen the topic.
I would therefore like to involve those who are interested in the deepening of the theme, trying (with the help of a professional) to correctly understand the meaning of the maps and their respective values on their axes.
To develop the study, I provided a map Bosch EDC15C7 they will use? purpose "teaching".


I will start the analysis from the main floor: IQ (Injected Quantity)!
- Def: This plan should be the main one who decides the amount? of fuel to be injected into the cylinder, but what indicate its axis, and what are his points?
- On the X-axis there ? a scale ranging from 400 to 6400, with intervals of 400 points.
- On the Y-axis scale ? from 1000 to 5000, with intervals of 250 points.
- The Z-axis should be the quantity? the basis of diesel fuel injected in mm3.

I hope that this discussion can be of interest to many and have a great participation... :)


PS: if I have committed any error or inaccuracy, correct me! ;)

[bart]

Good: I started from the bottom... :D




however, I think what you posted is not ? a map iq but a map conversion nm>iq....
in fact, on the X-axis should be riportatati the nm up to 640..
on the Y-axis should be the rpm...
we still expect that some of the professional user to confirm or deny my statement...



For completeness of information, the control unit in question ? mounted on a Fiat 1.9 Jtd 110CV.

if you put the ori can we learn more? people

Hi munro, I'm sorry if I was misunderstood: I am not at all touchy so I was not offended! In addition, I understand that your "critical" were made in a constructive way to improve the conversation! :)


I have identified two floors, which I believe can be plans DW you mentioned:
1680
(Wait for confirmation)

First of all: what are really the two plans that I named DW1 and DW2? What is the difference? between the two?
We then go to real analysis:
- Def: the we have already? date, and the cio? determines the amount? of fuel to be injected in the combustion chamber as a function of the rotation speed of the engine and of the request made by those driving through the accelerator pedal.
- The X and Y axes: the engine rpm and the percentage of "opening" of the accelerator pedal. (I hope to have them listed correctly in the table)
- Z-axis: cos'?? (PS: incorrectly, its values have been multiplied x 0,01, really? the two plans have the full scale one at 6500 and the other to 7000)

I hope that you have not made too many mistakes this time, even if the appearance of the fixes...

[goku]

Perfect ...I was looking for a discussion of born for educational purposes..I hope to understand something

[bart]

So we were able to define at least the main floor...

Now, before dealing with the other major projects (such as turbo and limiters), I would like to ask for clarification on one that intrigues me very much: the SOI!
1681
What are the values of its X and Y axes and how they are converted?

[megamind]

Please can you make visible the image. in order to be able to participate in me that I have the chance? to see them?

This only depends on the fact that you do not yet have 50 posts (as provided in the rules of the Forum), but they're close... :)

...honestly, I never understood why? are two DW but someone says that the second DW is used by the ecu in a kind of mode? sports....
however, don't take for liquid gold all of us? that I write to you even why? I am a person subject to errors as all...

As "a kind of mode? sport"?! What does that mean? It seems to me a thing not very realistic... As the attiveresti? Pi? likely a "normal" and "recovery mode", but this also seems to me not likely...

[msport (exil77grande)]

not always who does this work can reply to all, or to know everything,we know that every day you learn new things.

[magi1984]

for example in edc16 vag maps pedal are even 8 or 9, when you edit them all with the same increases in cos? you are sure not to miss!

[bart]

the second map DW if we make the case to 5mg of diesel in the pi? of the first and not the active you in case of edc15 but ? the ecu itself which should choose one or the other map as a function of internal parameters, first of all the speed? you push the pedal.....then again pu? be that I'm wrong then it would take the intervention of some user to big....

That's strange: must it? deepen why? there are 2 maps...
It seems to me a bit strange what you say, and what? working in function of the speed? pressure of the accelerator pedal! If (as you claim) the map the pedal ? the main map, then it should be one and unique!




for maps of the soi typically, these have in the axes :
X:rpm
Y:mg/str
Z:angle of injection advance to be converted to 0,023437
https://www.professionalchiptuning.net/showthread.php?1213-Convertire-i-valori-delle-mappe-su-centraline-Bosch
the one that you posted you are not, it seems to me a map of soi...

Sure that it is not a map SOI?
With regard to the Z-axis, I used the same value of conversion of the post that I've reported, and those obtained are gi? the real values of the advance injection?
With regard to the other two axes, I have some doubt... One could actually be the deal? fuel injected (even if the scale of values ? that is a little strange), but the other I doubt that the engine rpm: I have never seen a diesel road and turn 18,000 RPM...

[bart]

for example in edc16 vag maps pedal are even 8 or 9, when you edit them all with the same increases in cos? you are sure not to miss!

And they are all 8 or 9 of the same, or as in this case, similar but with different values?

That bad habit have the manufacturers put redundant tables! :(
For? we say that, at least in this case, they've succeeded to confuse ideas...

Should be changed, all with the same increments as a percentage (then a multiplicative) or in value (and therefore viscosity)?
Thanks! :)

[bart]

Not ? that simply need to be converted, the values on X and Y axes?

[bart]

I wanted to create a discussion that could be helpful at all and instead, so far, I have done nothing but create confusion... :(
I apologize...
I rinchiuder? in punishment until the avr? the ideas for the pi? clear...

[megamind]

Sar? a life iJn 1800 may be the prex of the rail (I have not seen the map posted) shot to guess

I confirm that I have the two drives, wish i.e. pedals

is the map an overboost:o

[bart]

you are the one who surrenders at the first difficulty??
continue to post your questions and don't apologize for nothing....

Thanks for the support munro! :)
I have absolutely no intention of giving up, but being the party with the wrong foot, I decided to reset everything and start from****! ;)

[bart]

Hello mavaila1972, thanks for your contribution! :)

[isfedale82]

I had said it before, but not listened to me...***** s, 50 posts are reached early by...just being a p? most visitors frequent the forum...

for? it happens to me in many discussions I read and just, why? you can't? see...

[isfedale82]

I hope you read things that are good and useful....

I'm trying to understand something about these maps, but I see in the climb

[dvdtuning]

sorry bart you can view the map, "soi" in 2d why? I ? pi? easy to identify the map...

[bart]

sorry bart you can view the map, "soi" in 2d why? I ? pi? easy to identify the map...

Hello dvdtuning, you'd be happy willingly, but I have not managed to locate it... :(


For the moment, I was able to recognize the right plans and the principal axes...
I have searched everywhere for a Damos, but to no avail... :(

If anyone is interested, I could start posting them one at a time (in tabular, 2D, and 3D), trying together to understand something more?...

[bart]

Hi munro, thank you for the link! :)
I seem to be the same that I have, and unfortunately, it lacks what I need... :(

PS: decompressing it gives me an error and won't open all the files: can you please test it too? Thanks :)

[marco]

these are the discussions that I like, thanks girls.

[bart]

these are the discussions that I like, thanks girls.

I agree! :)
Especially if I'd arrived at the desired result... :D

[bart]

Thanks munro: you are very kind and helpful! :)
Try again, and then do the update... :)

[sportknight]

sorry guys,cos'? the SOI

[megamind]

The beginning of the injection, and the advance of the injection start of injection.
