who tells me how to moddare the duration map of a vag tdi pd?

[munro]

from a peek at this screen so you realize how much stuff c'? and the distinction that you make between maps soi and the duration that you can also call maps eoi...what? end of injection= end of injection..what for? I did not understand if the maps of the beginning of injection are more than 10,without counting all the other maps soi in the screen,because the duration are only 4??
ah..this is a file hexump of the audi a4 ecu edc16 as you can see in the screen...

*sportknight look at these screen so you realize how many maps there are....
read the maps on the display of the left...

Annex 2284these are the soi of a golf 105 tdi with dpf
I have changed for each curve from 80 to 90 degrees adding 120 points and the cio? almost 3 degrees
for calcolarmi the individual curves I started from the first that are easy to distinguish

Before they go crazy, you can please tell me which values of conversion are you using on the axes?
Considering the plan 1D69B4:
The X-axis goes from 861 to 5000, then I guess they are the RPM --> coefficient of conversion = 1
The Y-axis goes from 3000 to 9000! What it should be, and that the coefficient of conversion used?
The Z-axis, say, be the degrees of advance: range from 950 to 1400! That coefficient used to convert them?

[munro]

for the z-axis, the conversion should be made for 0,023437...then 1400 points are 32,8 angular degrees of opening..
for the y-axis that should be or iq or temp engine,I believe the most...the conversion factor and 0,010000....
p.s:to tell the truth bart I'm losing all my hair....

A question, probably stupid...
Does anyone know how is it managed, the injection pressure on this type of engine? It is purely mechanical, without any electronic control? If anyone has any documentation on this and wanted to post it, I would be grateful: I'd like to deepen my knowledge about it...

Thanks munro! Interesting...

I open this discussion because? I wanted to sapene of pi? on these engines, in particular, I have in the workshop a tdi 3 cylinders. I have read I think all of what ? written in Italian on the internet in relation to these maps, I quote:
the maps that regulate the duration are 6, 2 of these are 10x10 and you will find one at the beginning and one at the end, I read that "they are at full load" but I don't know what it means.
the other 4 are for the 4 thresholds of temperature of the motor, from the pi? cold to the pi? hot.

then some of the other maps are an important part of the IS (injection start) that are 10 maps in a row without the axis shown, very strange why? should adjust the timing advance, fuel injection for? if I enter the conversion factor 0,023438, I observe that the values are completely unpacked (someone speaks of an offset). About IS I read that you change in the negative.

Someone can? confirm if there? that swap ? correct?
Thanks

edit I was wrong to write, IS not to rule the advance, but the angle of the beginning.

[magi1984]

full load means that the maps are used by the ecu when you crush a tablet of the accelerator pedal

That the control unit mounts to the 3 cilibdri? Always bosch?
