Injection Choked In Edc 15C2

[CHIP TUNNING]

Dear colleagues, I present to you are Emilio di Caserta are new to the field and with experience of almost zero.

Please dear colleagues, I say if ? true, what I understood after reading a 15 forum on the injection choked?

From what I understand with ECM TITANIUM on a EDC 15C2 :

INJECTION CHOKED (2) ? a limiter smoke this? adjusts the amount? diesel fuel is injected at each position of the throttle.

INJECTION CHOKED (boostxrpm) map1 ? the qunatita of diesel fuel from 0 to 2800 rpm

INJECTION CHOKED (boostxrpm) map2 ? the qunatita of diesel from 2800 to 4500 rpm

Please dear colleagues correggettemi if I'm wrong but please in a simple way, why? I have read many threads on this topic but with answers that are very difficult and I did not understand nothing

Thank you all in advance.

the limiter smoke works on the basis of the engine speed and flow rate of the intake air (if ? maf based) or as a function of the boost pressure (if ? the map based).

The other 2 maps you mentioned are the injection timing or ? the injection time required to obtain a given flow of diesel fuel to vary the rail pressure.

So if I have well understood, increasing the values of the map injection choked (2) I modify the stoichiometric ratio of that? I give the mixture more? fat?
Or am I wrong?

Sandro sorry about these other two maps, if as you say they are the times of injection to obtain a given flow rate of gas, then we want to say that increasing the times you will have a higher flow rate of fuel? Or am I wrong?

the scope, when we talk about fluids, ? the quantity? the liquid that passes a section in time.
Acting on the injection timing, the amount? diesel fuel will increase? definitely, but certainly not super? the value IQ max set in the other maps (Eg. Pedal, torque lim and lim fumes). The ideal ? need diagnosis to quantify the increase of diesel fuel obtained by acting on the injection times.

Thanks Blond. then as you say if the increase in the numbers of those two maps avr? a flow rate of diesel increased, and also a best high fluidity? of the medium?
Sorry another question why? in these 2 maps we are talking about taking as an example the first column of that? the 10% loading why? the values that we are not to descend gradually, that there are jumps, to make you feel better, I input the values of a column: 930 712 556 614 545 534 465 413 these are the values of a vertical column, if you see the second value to me, not ? reasonable, in fact if I look at the 3d map at that point you notice the vacuum.
And was caused by some remapper or ? the original?

I'm sorry, I was wrong to write to me again the third value does not ? reasonable cio? the 556.

by increasing the injection time increases the diesel as much as you want, in spite of all the torque limiters or smoke exist, try to believe, the trick lies in the fact that by tricking the ecu it does not realize that with a time of injection pi? high the flow rate increases, then a diagnosis just by changing the injection timing you can? observe other than just "stretching" of these, the flow rate (apparent) will stay? that established in the original map.

Unfortunately with the diagnosis, to the hand ? cos?... At least on my car (edc15c5) the quantity? IQ does not rise beyond a certain threshold, however, the test has increased by 300 points, the injection times this weekend:HERE but still have not had a chance to update the topic with this last test done.

[SandroMarciano]

no, not necessarily, you CAN make the mixture more? fat, but typically are in the temporary or to the limit when you're at the maximum

[CHIP TUNNING]

What do you mean with transient?
So if I bencapito increasing the map I should also make the throttle more? sensitive, and then we have a link to that other discussion.
Or am I wrong?
