The fact today is the log of the opening of the pressure regulator of the rail.
At this point, that the problem is not a limiter of the regulator?
I found a project winols a MJD8 where there are many maps from the damos... not all... and I'm trying to compare, since many maps are similar... kind of like the bit of the limiter of the rail starting from the damos and by searching on the file of the MJD6 it seems to me to be almost the same...

In mjet8 75-90-95cv file 2mb, the bit limitation of the rail is not ? the same as the mjet6 70cv file 448kb, in mjet8 bit of limitation is to be found almost at the beginning of the file, wrapped in the bit 2 have the same value 0384 esa, 1700bar normal..in the 70 the address change.Originally Written by Fede78
The patience and virtue of the strong..
to overcome the problem of pressure "swinging" I think you need to intervene on the map pre-control drv....
I think that is sort of like a pid control for the rail pressure...
for? don't ask me where it is located above the map why? not n? I have no idea....
I read only...
A rider does not create queues even in the car...
a automoblista create queues even on a motorcycle...
Some advice in order to stabilize the pressure of the rail?

the maps above taken from the file lancia Y annex at the beginning of the forum, in addition, look for the bit 01d4 0307
change the bit 0307 in the same way as the bit restriction rail pressure

The patience and virtue of the strong..
Sure of the values of conversion? Do not come to me...
I'm sure to 100x100, do not think to find the values the expected and easily compressible,
we are talking about the rail as a function of, for example rail f(rmpTB, Pboost), in practice it is a function of that spread of the values in a table with x= rpm y=mbar, where x=rpm and y=pressure turbocharger from the report, it is evident that the unit of measure of the values in the table ? bar/s
The patience and virtue of the strong..
Type in the map of the rail pressure 0675BE indicate a conversion factor of 8 ... but in the map we have 1500 that should be already? the value of the rail at which we need to remove the offset of 100, and then 1400... and as a conversion factor for the axis of the mg/stk I is a multiplication factor of 0.002941
also 0674BE tell me of such a conversion value of 50 - offset of 100.... but taking the peaks that have a value of 199 we will have 199x50 - 100 that I get from 9850... that I do not understand..
and cos? the other
I looked at these entries in the damos of the MJD8 and actually have those things that you say but in the MJD6 I are values out also why? perhaps in the first maps are 8-bit while in this 16-bit

Map 0675be lasse indicate mg/stk cio? Y in reality? ? mm3/stk value conversion 0,002930,
fix the conversion value that in transcribing I typed 8. instead of 1
Map 0674be Rail pressure max gradient has the unit? bar\s (the cio? in other words, speed? rail pressure)
Certainly if you don't see properly, you can't get out of it,
067494 8bit
0675be 16bit display normal 8bit ratio conversion x8
0677be 8bit
etc..

There guarder? better tomorrow, what time are time...
But in substance, that limit and what is the meaning of these maps?
Request rail pressure at cranking
PrailRef warm-up weight map
PrailRef warm-up factor map?
Are 3 maps that in fact I was not touched... why? I didn't understand and I still do not understand their operation.
By placing these you have solved the problem of the pressure jump?
