the map voltage pump vw tdi 90cv

[munro]

Caio guys I open this thread to ask for opinions,advice and information in general on how to edit in the best of ways, the map voltage pump that ecm calls "the injection correction" on the vw with a rotary pump vp37....

from the outset, that I do not n? I have never mapped for this car and unfortunately I don't know how to modify the above map informed....

if some pious soul to me will take? say to him, sar? grateful....

in addition, for the sake of completeness of information it has to be said that the car mounts a pump head increased from 12mm in place of the gold 10mm and more injectors bigger 206 microns in place of the 184....

I have read a p? of info around and it says that you increase the map in question, on average, between 10% and 15% more on all of the same...will be? true??
I am attaching the link of the file ori http://www.professionalchiptuning.ne...6-golf-4/page2 post 19

Hello
I have not seen accomplished, but in the map of the pump, the value here to the moved are 5200mv, the car goes into damage you accelerate the whole.

so guys, I made two calculations, and I hope not to give too much numbers....
speaking with a diesel technician reported to me that on average, each mm increase in diameter of the pump head port, an increase of 21% more for? you have to subtract something for a speech on the efficiencies of the pump and the temperature of the diesel fuel, etc., etc.....considering that not all the diesel fuel in the most provided by the pump is actually delivered unto the injectors I have done the calculations by taking as a reference the 19% of diesel in the more that is given for each mm increase in head pump in my case the head and 12mm so it would be appropriate to expect an increase of 38% more fuel...always the same technician told me that a vp37 pump with piston and head from 10mm pu? give to the max 58mg of diesel....then 58+38% increase we should have an increase of iq 80,4 mg....we can therefore say that with the same voltage original pump now, however, we will have 38% more fuel....my doubt stems from the fact that with the engine at idle for example, if first we wanted to 4mg and 1.7 v for it to turn at least now he gets 38% more then the total f? A 5.52 mg total obvious that the motor with the same voltage pump to a minimum, say, of 1.7 v is more accelerated....of course with the map I posted you ? had to intervene on the actuator to lower the minimum....but cos? doing I think that the pump is not able to provide me with all the diesel fuel, because with the same voltage, however, the stroke of the actuator now and less due to the displacement related to the adjustment of the minimum...
how should I act in the map voltage??remove the 38 voltage in the turns that interest me to return to the 4 mg ori to a minimum??then to 1.7 v-38%=1,054 v??

Hello
This map can not speak of the increase in %, the values are "mv", and the maximum value possible in the map are 4800mv.

Hello gezame,thanks for the answers, then modificher? the map following your instructions....
the cio? everywhere not to? exceed 3931 points, or 4.8 volts.....
but for the intermediate laps as I move?? and my reasoning on the minimum is not good??

Hello
It changes the rpm, intermediate (I think you talk about IQ, no rpm), in acelarazione, the car smokes.

[munro]

ok..but how do I change the "IQ intermediate", and then the tensions pump about to get a good performance from the engine, but without smoking too much the car?
you can? calculate the all-or v? trial and error??

Hello
Trials and errors, not all the car has the bomb, and the injectors are you iguale of desgaste,etc.
Sometimes included the copo de the injector difere de a type engines other.
