MARELLI MJET impariamola!

[turbolic]

I have not stopped, I have read it dozens of times in the post, especially the tips of Backgroop, but to me there are still too many bases, I can not stabilize the pressure of the fuel by changing the two limiters 775
I tried again today but nothing, I tried to get them to 800, trying to bring to 1500bar the other maps, but there are some addresses that I totally displace, in the attached image you will notice that with the pull of a gear, the pressure rises and then begins to oscillate.........sooner or later we get there!

a greeting to all.

Yes, he does the same to me, same behavior.
For now I gave up... now would be to understand if there are other maps, "interesting"

[munro]

according to me, the rail fluctuates because the ecu has a pid control on the valve drv like the ones for the turbo...
the oscillatory behavior of the pressure-in fact, I f? think you have pid control that seek to follow what is set in the map-rail, but all in vain, because they did not set with knowledge in these blessed pid.....
it is available....on the bosch? someone said to me that there are....

on the bosch there are the PID relative to the rail, if you are interested in knowing where are you, I point them to him, on marelli I assume that there are even here, otherwise the pressure would peak absurd standard. However, if the pid remain the original ? you may experience this oscillation (unless a high pressure pump other than that series), the only possibility? ? that may have been modified along with the rest of the maps...

[Fede78]

In a damos how you could call this PID? Simply PID or other names?
Just take a look at the project ols of the MJD8 that seems to come from a damos. Then if I can find them, maybe I can see if I can find the equivalent on MJD6.
Indeed, I'm attaching this project of ols cos? you that you are ir? experts maybe understand something more?...

The file ? the annex at the beginning of the previous message... but you can't? to edit a message here on the forum? Type now that I wanted to put the link to the attachment in the bottom of the message?

[SandroMarciano]

on bosch you have there are from 2 to 4 for each operator: P, I, D.

There are Nn pid to change, not to oscillate the pressure just change the maps in the right way, I have come to a point 70 to 1590 peak, I can just place the mod file..

I'm sorry I don't have one with you, but today I don't understand anyone, maybe I write too confused I...
But I also argue that with series components, the pressure must necessarily stabilize even with the pid of the original, indeed, that it should remain as such

Sorry guys but looking at some maps of the mjet I saw that the myth 90 hp has a map pedal different from that of the gp 90 hp and this might be the hole under 2000 rpm and it feels a lot less, because then some of the other differences in the map I don't see

S?, by aligning the maps pedal c'? a difference of 30-40% in favour of the myth at low revs
