MARELLI MJET impariamola!

[eobdexpression]

I tried the file with only the rail and related limiters changed with the times (stretched), but all of the torque limiters ori.
But always error fuel pressure and pressure that, however, doesn't it ? stable and in any case does not rise above the 1490/1500 bar.

From the tip of Backgroop I also modified the other two bits in my file of the point (but also that of the y as they are identical) to the addresses 655D4 and 655DB that there should be two other limiters of the rail pressure (eprom*2-100)

But even with these two bits, the situation does not change.

Hello if you always recovery can be more? one of the reasons:

Sensor flute rail damaged
error bit modified
error why? there are other bits to change

[Fede78]

According to me c'? some other bit or I can not understand the map well 67A06... limiter rail in function of the temp of the diesel... " for an axis, I the temperature of the diesel but in the other should be the rpm... but I don't understand the conversion factor, and if they really are spins or no...
I say cos? why? even with no change in these 4-bit single you talked about here in the discussion when trying to go on with the rail I had the error also making maps from 1450 bar while if I remember correctly, some time ago I tried a map from 1480 bar and that gave me error... now I can't find it on the pi?.. are in pi? 110 the scriptures....

The alternative would be to change the bits of the gain of the sensor rail... knowing what ?... cos? to do ir? or less what makes a form. Of course, in the diagnosis do I have to do a map type to 1400 bar which is actually? then they will be more? as the sensor reads less than the actual pressure and therefore the pump pushes the pi?... drawback then ? as an analog module with the linear trend, and then I would have pi? pressure always...

For now I put a map at 1430, and goes to that ? a show and, above all, no lights. That of 1600 bar was one of my obsession to replace the injectors, 1.3 95 hp and get them to work precisely to 1600 bar ? the pressure of work.

In my panda, however, does not turn on the light, even midificando the two bits.
For me, the pull on the pressure ? an obsession, my goal ? try to smoke less, in fact, the performance I got out of the car are more? that satisfactory, it should be already too much compared to its road-holding, not to mention that I have to mount a reinforced clutch perch? slide in continuation.
For? if you pull up the pressure I can reduce the times of opening and probably smokes less, around even with the original turbo( diagnosis to a bar exactly) and maybe ? for this reason, smoking pulling.

a greeting to all.

To me, the light comes on if the pressure in the diagnosis exceeds 1450 bar about... if the pressure is under no light.
But if I make a map of the rail even to 1450 bar (a value of 1550 in the map) then turns on me the light why? can I have spikes of 20/30 bar above the set pressure.

Why? do you want to shorten the time of injection? inject until after the TDC and will cause fumosit?? I ask you, why? I'm also trying to decrease the smoke? I have injections cos? long.

Strange, to me, doesn't it ? never turned on the light with 1450 bar, while with 1460.

I can not understand one thing: why? the pressure, the ori, after the maximum peak ( 3750 rpm - 1400bar) drops with the increase of the rpm to 1320 bar? It is a change that makes sense (and not detrimental) to bring the high rpm, all at 1450?

Well maybe to me, at 1450 (no) and 1460... I have made many maps, and pu? be that I am confused.
The pressure after the peak drops why? set cos? in the map ori.. if I ask why? the engineers at fiat have designed the cos? then I don't know...

I think that sometimes you have to also know if the mechanical components such as the rail so the pump,injectors,fuel injectors,sensor flute rail pressure, are perfectly intact, without any problem, why? just one of these mechanical organs do not work properly, here is the explanation of the problem of recovery.That's why? c'? people who do not have problems with errors caused by the pressure even if modifcano the two bits, bringing the pressure even at 1600 mbar.

For what I know I don't have a lot of riusciscire to have 1600 bar in the engine 70CV... in the 75 ? a different story. To my knowledge there are only two cases, Backgroop and a trainer that I've read here in this or another forum, Bobracing.
Here we are two or three users we are trying to do and we have the same results then according to me missing some small detail.

hello, excuse my intrusion, but reading the post I am very passionate and I hope that little by little, it will go on to understand the dip!!iu' on the marelli being myself the owner of a great point mje.
I miadomanda and': I've seen formulas in which it is indicated 2* eprom
But eprom what corresponds to excuse the ignorance but

Corresponds to the value read on the map. As the axis of the prex rail in the map of the duration where a value ? for example, 600 with conversion factor 2*eprom-100 then becomes 2*600-100 = 1100 bar.
