hi guys,I would like some information
I have tried to examine a marelli 1.3 mjtd 90hp with ecm titanium
but the maps are to the contrary?? ? can or I don't get it?
cursed marelli,so in practice the driver does not serve a caiser
and given that I am a good guy I'm attaching the flash and I will tell you as well what are the maps
and a reading is made with rooster v2 bdm?
excuse my extreme ignorance, as to the coltrario?
the marelli are a bit special
for example, there are some maps that are to be read and written in 8-bit instead of 16-bit as those that relate to the rail and the turbo
then there are maps that are to be read to the contrary, from right to left, as the injection timing
of the series that's why? there are few people who know where to put your hands..
well,I up to 2 minutes ago even I knew this,but now I have already? found the maps and figured out as well as increase...
I think that if you put yourself to study something something always comes out...
In the marelli all the shapes of the curves are strange, for example the pedal and the torque limiters.

Ps. Also the torque limiters are to the contrary
but then the driver in the ecm how should you develop? I am a neophyte.
On the driver there? nothing. ..little stuff, tomorrow anyway, I put some of the addresses
That's why? I didn't understand the increments in 2d, and especially some of the values of the limiters negative... The addresses are the same for the 75? I do not believe?...
no,they change from sw to sw..
as promised, here are the addresses that I could find the file that I have attached
8 or 16 indicate how many bits you need to display the map
084BEA torque limiter 16
08ABFA injection time 16
08E618 torque limiter 16
08E638 torque limiter 16
08f1cb rail pressure 8
08d46e limiter rail 8
08f484 rail pressure regeneration 8
0903c2 pedal 16
0904f2 pedal 16
090626 conversion pair 16
091b44 pressure turbo 8
091d08 limiter turbo 8
0920dc an overboost 8
09221c an overboost 8
08e688 advance 16
08e868 advance 16
c'? no error,those which I have indicated as maps of advance should be maps of the limiter fumes (maf, map etc)
in addition, there are other 4 maps torque limiters but I don't know if they are depending on other variables type, temperature etc...
a doubt just me ? remained
I would like to know how to increase the injection time as they are drawn to the contrary?
Attachment 3377
Found the other limiters, now I understand very well the history of the maps on the contrary, to change the timing of injection
If you help me tomorrow put all Hi, the conversion factors I found :p
Great sporknight! However for? the form should be similar, right? I am a new but I like it and I try to understand something...
you are similar to,but I also understood how to map the injection times and I also found a bit of conversion factors,cos? we summarize everything and we are useful to everyone,as soon as I can I do all of that
Thanks! After lunch I put on a bit at work and let's understand something. Aspect that places something for more doubts that 100%will hihih
I, unfortunately, on the marelli I don't have direct experience, you should do some test to see if the individual curves and the whole map should be read to the contrary, that is, the last curve in the real world? ? the first, or only the curve itself should be amended to the contrary...as torque limiters and the pedal.
Then, tomorrow I will explain all, they are not to the contrary, seem to
in practice, it seems, on the contrary, compared to the bosch, but by examining the bp you understand why? on the other hand are
so guys
084BEA torque limiter 16
08ABFA injection time 16
08E618 torque limiter 16
08E638 torque limiter 16
08f1cb rail pressure 8
08d46e limiter rail 8

09221c an overboost 8
08e688 lambda 16
08e868 lambda for hi hq 16
090ff8 4 limiters below
the conversion factors are
% pedal= 0,004
temperature= 0,5
press rail= to 7.51
lambda=0,001302
maps soi=0,015625
lim torque function temp =2
turbo=14
iq= 0,002941
Great!!!!
In the 75 hp, the conversion factors are the same?

hello,great job! what do you mean by conversion factors? thanks!
it is,in practice, are the values with which you can calcolarti what corrisondono the breck point and the curves of the map
if you know that the map indicates pressure diesel fuel, multiply the value read by the conversion factor

No, looked at the map that I have attached and see the maps that serve to you
Voglioimparare. I did the test to sovapporre the maps of the two versions, the 75hp ? a p? different, while the scroll should be offsetting, but riallineandola, you still can't follow it. Then, check the type of curves to be posted to the addresses of the 90's, and rintracciale in the 75.
I personally when I work on a map that I do not know or that ? a little different works in dual monitor, one side of the map, of which I have the addresses and other map that I have to do, the type for this marelli I did cos? why? I had never made

guys can anyone tell me politely on the 75hp version addresses x turbo pressure? thanks!
if no fap ? mechanical handling
Guys in this part of the turbo, if you want to know the addresses you need to put that? the map otherwise, how do we do it?
