First map multijet

Hi guys, today I made the small hours because I spent the whole night messing around with the ecm, read and try to understand all the info that I had available on the forum and on the web about the maps multijet.
I have already said that I have chosen a simple map to start but for the moment I have this car.

Therefore, searching on the web and here on the forum, I tried to interpret it (using conversion factors) and edit the various maps that already gave me the driver in the ecm (maps out drivers I don't know how to find them are still very inexperienced) , now I will explain how I have changed.

I have to say that I have used mainly the grid with increments through percentage.

Deleting the EGR.

Injection home: some write that it is a map pedal with the Z= mg of fuel, others write that it is a map that is inherent in the rail pressure, so I have not been able to interpret it well, but from the moment I read that 'iniez. prov. and the torque limiter(2) are almost of the same pace I tried to increase something according to a logic of my own having played for a little the values.

Therefore iniez. parz: I increased from 1600 to 4000 rpm, from the 31st of load of 14%. Then by 4500 rpm from the 31st of load of 11%.

The second map of the injection I have not touched here on the forum I have advised to tap all of the maps dates from the driver unless this.

Torque limiter (2): for this map I followed what is written by the more experienced users (that is right or not I don't know), going hand in hand with the map injection.

25-load, and from 1500 to 4000 rpm = 14% increase
25-load, and from 4500 to 5200 rpm = 11% increase

Torque limiter #2: this map I understood that it should be torque in n/m based on the coolant temperature and you have to convert the value using the conversion factor 0,023438 (I Say right or I say crap?). Read the advice not to increase more than 10%, and I increased all by 8%.
Going to see it on the web it was said that to eliminate that hole in the gear change it was necessary to modify the last three curves (in 2D) and bringing them hand in hand with the other, and so I did, in tabular form, the value is aligned to the other (I've done it right or is it wrong?)
in tabular form: from 94 to load and 1300 rpm up to 4500, I brought the values up to 6662 to align them to the other.


I've read that it should be the actual torque limiter, but when I open it I find myself in front of the table with only the engine rpm and the values and that's it. what are they indicating? how should I increase it? following what logic?


I accept any type of judgment (if they are constructive and will be followed by corrections/explanations even better), they are here to learn and not to see the map nice and ready because the machine that I'm trying to do is mine and then I would like the satisfaction in my personal.
If you have any manual (in pdf for example) with the various conversion factors and the various values, etc, etc, I kindly ask you to the admin if I could go if there was and given that I still don't have the permissions to download from the forum.



In the attachment file ori and mod

without that load this map...
please take time and study this discussion http://www.professionalchiptuning.ne...hlight=Marelli.
Tonight if I can I'll give you some tips on this file..

I started to read the post I was hoping that your study you have made to understand at least the basics of the operation of the ecu is the sw that you use to edit the file but as soon as I read it,cit': iniez. parz: I increased from 1600 to 4000 rpm, from the 31st of load of 14%. Then by 4500 rpm from the 31st of load of 11%.
I fell arms...don't have any kind of load in this ecu believe me, I do as you advised cinqueturbo read before all the discussion linked is then maybe you will understand what I mean..
between parentheses, the five is one that on the marelli sa veeery longer in me, because it has a 1.3 which is 3 bar of boost, turbo and then listen carefully to his advice and make the treasure...

Cinqueturbo not the load of course, before a positive opinion haha
In regard to the discussion that I've linked to in the night I have taken account of that, do not deny that, however, I has also created a bit of confusion for this I went a little blind..
as soon as I can maybe I will read everything with more clarity.

Munro are in increments as crazy as I can understand from your comment then.. haha

I do not speak of the increments, but the word "load" that on a diesel, and on this ecu does not have sense...
studies better a single map you understand what you have in the axles and you will understand..

however ketto21 have you done a review of that post?

tomorrow will definitely be slower then you I will be able to give assistance..

let's start with these..

0625CA Lim. Pair
063F40 Stage iE
064C74 iE Partially.
067F4A Lim. Pair
067F6A Lim. Pair

hi ketto 21.

the best thing would be, according to me, I started with a map more simple, the first map with a diesel, if I understand you does not seem too excessive?

I first made on a small petrol with a lot less parameters.

and still today, after almost a year, I have made some I still don't feel to put the hand to a diesel, much less multijet or comon rail.

you wrote in the first post that this job you're doing according to your logic, staff, correct me if I'm wrong.

and can know on the basis of which parameters you are making the changes?

I ask because I'm practically studying a large part of the mechanics, pressures, parameters, injectors etc

I do this not only for the passion towards the mechanics that maybe what pushes me a little more, but also know up to how much I can push it with the changes.

If you want my advice I would start by assessing the 3 key points.

1 basic course
2 a tiling with those who know the engine and work parameters.
3 begin from the bottom, with a small engine, as I think many did and I'm doing it.


Attention I'm not saying that the information in the network that you have found are not good, but they are very fragmented, and without a solid base, does not go very far.

this is true for all things, not only for this.

I do not agree with you mustangGT, because it is absolutely better to move the first steps on the diesel than on the gasoline, in fact, just think that 90% of the mappers are not able to map the gasoline, which are much more complex and delicate and that if you don't know map immediately notice that it's bad or that in the worst case holes easily in the piston instead of the diesel also did badly notice the difference and the damage to the surface with time.

I can't download the file of your opel .. but I try to aiuterti a golds that I have always opel
in the meantime, the limimatori rail and turbo in this marelli the visuliazzazione is 8bit

chiusua egr --> 084670 to that address and change the value to 40000

084b30 lim couple
088fb4 lim couple
08ada4 map injection this needs to be changed from right to left .. that is to understand the maximum load is at zero percent as you said at the beginning
08e840 lim pair and the other similar
090606 lim couple
09084c map pedal
091248 lim couple
091272 lim couple
0912bc and 091308 lim torque for gear
091512 lim couple

I also have other maps maps important in the meantime, the draft and try good study
