EDC16c8 maps, turbo, and more.

I would like to ask for enlightenment on some of the maps of the ecu EDC16c8, which I've attached in another discussion ( I hope not to combine disasters by putting here the link http://www.professionalchiptuning.ne...gr-vt8287.html), and more precisely I would like to ask if the map at the address 0F89E8 (after the 3 maps turbo 0F82DA, 0F851E and 0F8762) ? a map of the limitation of the turbo boost pressure as a function of the external pressure(altitude)? I say this because? on an axis, I see values ranging from 630 a 1086 that I as an absolute beginner I interpret as the atmospheric pressure to vary the fee for? probably I'm wrong. I don't understand? the need? a map is seen that the values are always 2400mbar all over the map, in this case it was not enough just a bit of control?
The second map that I inquire ? that e-mail to the address 0FB4A0 that I just can't figure out what it is. Thanks for any explanation.

I am thinking the same, the boost limiter by atm pressure has little work from the factory.
The other map is the Inverse Drivers Wish.

Thank you very much biela. Cos? in case you want to exceed 2400 mbar in the previous maps turbo you have to change this otherwise I would be stuck at that ****llo, right? If ? cos? for? would it not be better to make the change let's say from 980 mbar up to 1086 in the table, why? vary that ****s pressure when there is a lot in fee could not overspeed the turbine, and then below 980 mbar stay stock?
What is the Inverse Drivers wish? It is connected in some way to map the pedal? And what are the values that are contained in it? See, at some points, 8192, which in many other maps represents the 100%, but here I wonder what?
Thanks so much again.

? also need to change the SVBL.

"Inverse Drivers wish" ? used in the control of the speed.
X=Nm, Y=rpm and %pedal.
8192=100%

Thanks Biela. The SVBL ? the byte just next to the table that begins on 0F89E8?
I believe that the tables that control the variable geometry are these 5 0F6A02, 0F6C46, 0F6E8A, (who are they all ? three identical), 0F7112 and 0F7356 that are identical to each other 2, so it really? there are 5 maps, but in practice 2, the first group of three and the last 2, if ? cos? I wonder in what circumstances they are used the first three, and when the other two, in addition 6144 ? equal to 75% of 8192, but it is considered as a total closure of the vanes of the variable geometry in order to maximize the exhaust gas? for example, whereas the value 2376, which represents 29% of 8192 means that we are at 29% of the total opening of the flaps or not c'? the correlation between this value and the effective aperture?
Thank you so much for the tremendous help you gave me.

SVBL=F8BE8
Some VNT maps could be for the DPF.
The higher values, the closer the vanes, and inversely.

Thanks a lot Biela are a valuable source of information.
I wanted to ask if ? correct this is my thought, what? if you want to make a change to soft (I mean on the map informed and not deceived), we say inject the right amount? diesel fuel up to a maximum of 80mm3 (I say up to this amount? why? I saw that the map of the duration of injection as a function of the rail pressure 0F4DC2 ? calculated up to that quantity?, otherwise the changes to be done would be many more? maps) pu? be sufficient to modify the driver's wish (0E14FE), the torque limiter (0E8E7E), the limiters of diesel fuel (0E924C), limiter, diesel as a function of water temperature (0E9188) in function of the temperature of the fuel (0EBF1A), all 3 maps turbo even if they are identical (0F82DA-0F851E-0F8762), the map turbo function of atmospheric pressure (0F89E8) and the limitaore SVBL (these last two changes only if you want to go over the 2400 mbar). Certainly willing to do the work much more? in the end you can? change the management of the variable geometry and much more but what I ask now ? if these are the maps that are absolutely essential or I forgot something. I would also like to ask if ? reasonable to increase the limit of work to 2550 mbar maximum pressure of the turbine GTA1749V or ? an over limit.
