View The Full Version : 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.

without that load this map...
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..

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

this is absolutely true that on the diesel if it goes bad something to notice.
but I personally I think it is more complex because you are dealing with many more parameters.
take a point 1.2 70cv injection....I find it more easy to modify because the cross-sections are a lot less.
with the diesel there are many more parameters from the tap.
my first map, for example, on a gasoline-forgot about the edit on the smokiness, and it went wrong from the start, visible I was lucky, but I think it is always personal opinion, that a petrol engine with 4 injectors, 2 lambda probes, regololazioni load and injection there would be much less to edit.
Then, I do not consider myself an expert,totally, but my opinion based on what in this period I'm studying.
Always persolalmente I believe that we start with a mapppa as complex as a multijet not a task that I would do.
Not different from a scodifica, luca stanca etc., is not only a reading of e2p and flash writing, to monte and good to know several things.

This is due from your misinformation as well as the drivers that you have are basic with the minimum of the descriptions..

but how must be useful to your help?
have you shot addresses to a file without specifying the HW nor the SW which also has nothing to do with her.. Booo't you have better things to do?
instead of polluting the post for others to read and be quiet..
Unfortunately not being able to download the file , I opened a file that I had a opel 1.3 .. peaceful that I didn't want to pollute no post was only to help cinqueturbo in two files opel 1.3 different I was with the addresses posted I thought they were the same
guys we go back to the topic.

hello!your "help"is very good if placed in the file on which you worked,so as to compare the two files,and for the record the egr off does not seem to me correct.......
then there are, first of all, the schoolboy who has to prove to the professor nothing.
the second thing I don't use ecm, not the ever used!
the third thing I'm not you're saying anything that I already know and I'm not even a boy, much less had any ateggiamento of the genre.
now that a diesel is less parameters of a gas in a specic multijet or the common rail, and a thing absurd, in my opinion!.....
then, when someone starts to tell me I don't want to count them etc., to demonstration that they have nothing to teach me much to share do you know what you're talking about.
the attitude of I am more experienced and you don't know nothing about it so will stretch to fish in the facca as a geek on Sunday and one thing that I do not, and it is acceptable.
here it comes to the share of those who have the longer I don't know if I have explained myself and this is not useful to anyone if not to the taunts and insults between the lines.
you say to me mappette and then I appoint winols?
have I missed something or the forum is based on sharing and helping those who want to learn??......
the presumption and the conviction of knowing everything sooner or later leads to some casino, and the big ones!....
talk about mappette and then appoint software from a few hundred euros!.....
I understand, lasica miss that, and better.
I continue to be of the parry that start with a diesel engine and especially so complex by putting percentages on the case and a waste of time, of nights sleepless, and they only make a mess.
enjoy the rest of the discussion I hope that our friend will succeed in his intent.
according to my opinion (for what it's worth, being a newbie towards you)and very difficult moddare a diesel that a benza sucked,but if you get it wrong on a diesel badly that goes smokes!on a benz if you get it wrong the complications are greater!
repeat this for those who perhaps did not understand the previous recall:
we go back in topic
the title says first map multijet,I did a bit of cleaning if you do not understand I still do more in-depth.
hello!your "help"is very good if placed in the file on which you worked,so as to compare the two files,and for the record the egr off does not seem to me correct.......
closing the egr on the 1.3 is carried out in this way.. quiet is a solution that is already tested .. in practice, bringing the value to about 40000 .. about 15v the ecu understands that in order to open the egr has to get to that voltage ... can't can't get there ever, and then the egr will be closed
tomorrow, you place the file ori of the opel that you said
Is not more simple and clean the old bits switch??
in diagnosis, you from the EGR disabled in that way?
on 8DF, and one of the solutions but they are 3 and I always prefer the bit switch
Five has the reason,according to me it is useless to shoot addresses for burst if not then you understand what it means, or better what must be done in a specific map.
I repeat, the forum is useful and is full of information just to try and understand what is being described then, if something escapes, you can ask for.
In this way you can figure out how to make the best of a mapping unit complete

I'm not shooting no address proof .. to do this mod for closing the egr ... working 100 % ... never any cars returned
I started to post the address of the egr do I do so .. then if you're not happy that we can faa
Scican on the forum I was one of the first to post a guide on how to remap and closing egr on the marelli 6jf.
Having said this, my post was not an attack or criticism of anyone, or simply said that it was necessary to understand exactly what it does and how it works a single map, especially for someone who is starting out and then move on to the complete mapping

munro, without a doubt ... but what I have said .. it really works .. I will agree to the switch , but I have always applied this mod , the address that I posted and the mod as you change , it changes the voltage , so that the egr does not open
around here , I didn't want to throw them out of the road one but I just wanted to help
Perk this topic has remained so. It seemed interesting.

I could hypothesize that the fiddling night is not successful.
the first map on a diesel, and come to a multijet!,erg switch, a confusion that is not good for those who want to learn.
first, to waive my first erg on a diesel, I have studied all the system, mechanical and electronic and not just. there are several systems of erg and has to be seen case by case.
touch the bit to the case without an expert close by if not that you want to experiment on your car I do not find it advisable.
I would be curiso as you know how it goes to finish this first map, and until now, according to me, forgive me, too many thing in the midst of that focus just with respect to the remapping!
maybe I'm wrong, but on a client the first map ever!.....or followed by an expert in the field.
Perk this topic has remained so. It seemed interesting.
Instead I think that this discussion is a dead end because of the 3 pages of spam and useless talk species from those who recently joined in someone else's house, shouting right and left, I here I them etc., etc.
Be calm I don't give a helping hand in these circumstances.. and I do absolutely give, even going to those who need you and the entire Group..

I would like to remind you that the forum is open to all members, what vuoldire in someone else's house!....you are a guest just like all the others.
you crept in, and talked about mappette assuming everyone is using the damos, or ecm.
and always the same old story, those who have for a longer time behaves that way only because in the proflo ec written average user or expert, by placing the corner of the newly arrived model com doormats.
The attitude that you show is not different from the operator of bank will lock the account on the Friday the money in because you're on the p****the.
this is not a proper attitude.
I have given my opinion, not a rule that prohibits and you are not at your home!
here everyone has the right to express their opinion, but for you and spam, and the"newly arrived" enter the house of others.
I think you're exaggerating!
is not conceivable to hack a car to a customer, or a friend who is worse.
the council may also be right but for a beginner it can be misinterpreted and if it's damage from your council saying" go with with the diesel and more simple" who pays?? pay you? I strongly doubt that take such a responsibility!.
I repeat, you are a guest as I am, and the fact that on the profile there is written that the average user doesn't give you the right to have a similar attitude.
Nothing persolale instead of you.
wuwu turn for the worse has taken this post, shame I was interested in the opinion on the egr mjd8 since some time I have adopted I the method of scican25 and genuinely works without any problems . in practice, it raises the opening value of egr from 6v to 15,16 v
first map,be it a diesel or benza changes little................it is DIFFICULT to!
the problem is that,as already has been said by the five and by munro,were "fired"addresses without a minimum policy!that is, without the bases on here, study this map!
it is already difficult to explain to a beginner the closing "standard"of the egr,let alone the mail from the friend!
there are rules in the forum,right or wrong they may be,are complied with!what is not done especially in recent times.
I don't know you, and what I'm trying to say, but some things have also been deleted because they are considered spam.
and how to design a combustion engine without the rules!...the situation here and the same. before a map ce for other things and don't have to hurry.
no one here wants to make spam, but like if I take a student of electronics in the first year, that does not even know what the positive and negative, and I ask you to connect and instruct me one shift register 8-bit and there goes the night to turn on an led!
the situation and the same, and the forum and the fact to exchange opiononi and try, all together, politely and civilly of the solutions and to make a map without any knowledge of the basis of talking about mapping, arriving up to now to shwitch erg it seems to me absurd.
we do one thing instead.
I can pass a manual important to the processing of the engine but before and need to know other things.
if our friend instead of spending the night needless smanettamenti and put values in the case explains that ****llo knows the machines, maybe the right road and start from there.
or not??
I am not in agreement with you....and your home do you.!
But six of crock!!!!! Forgive me but it was so clear!!and then, If contradictory,first you say that the average user,the expert feels superior,and then you say that it's not okay if a novice tries to do a map..........by on!!! Then this is not the post suitable to report these things......and are not an average user nor an expert.....just a simple enthusiast.
He forgot! The "home"is all you just need to know how to lead to a good living!hello...........
