How to recognize the maps of ecm titanium

[switing63]

I tried in between some of the log files and I got these data for a jtd 16v:

gas pedal 100%, the engine rpm 2077, pres turbo 2180, maf 1172 mg cycle, fuel injected 69,76mm3 (weight about 58,1 mg) from which is drawn that the air/fuel ratio is approximately 20,2/1 (1172/58,1)

gas pedal 100%, rpm 4000, pres turbo 2300, maf 1035 mg cycle, fuel injected, 60,02mm3 (weight about 50 mg) from which we get that the ratio of air to fuel is about to 20.7/1 (1035/50)

So given that the machine in question is a €3, and then quite permissive in terms of smoking compared to the vehicles I now think that keeping an air/fuel ratio that is similar and that is around 20:1 to properly burn the 80mm3 (66,6 mg) are needed, 1332 mg of air per cycle. Maybe we could settle for 1,2 gr if the ratio of 18:1 but I don't know, in terms of smoke, as does the engine

The place that the stoichiometric ratio of theoretical to burn the diesel fuel is 14.5 parts of air by weight to 1 part of fuel always in weight, and which 80mm3 weigh approximately 66.6 mg the minimum amount of air is around 1 grams per cycle.
Law is the diesel norm (EN590) must have a density of between 0,820 and 0,845 Kg / litre, so if you multiplied 80*0,820=65,6 mg, while if the multiplication 80*0,845=67,6 mg that is why I said approximately 66.6, which is a middle way.
If you then multiplied the weight of 66,6*14,5=965,7 mg. I said theoretical because no Diesel engine will ever be able to burn without making smoke as a tanker the fuel to the stoichiometric ratio, then definitely 1000 mg are insufficient.

Would you be so kind as To tell us you like calcolaresti How much air I should to aspire to a 1600, Which we took as an example in this topic With an absolute pressure Of the turbine (2.7 Bar)?

[switing63]

Look, I would do this calculation even if I am missing a fundamental fact.
1600cc/4 cylinders = 400cc per cylinder. 400*2,7=1080 which is then multiplied by the specific weight of the air that is 1,2928 ago 1080*1,2928=approximately 1396 mg and here, but I stopped because it lacks a fundamental fact that is true filling of the cylinder, and then, if we assume a 70% we would be at about 1000 mg/cycle, but may be more

[switing63]

In the example before 1900, in theory we
1910/4*2,3*1,2928=about 1420 mg but the MAF sensor gave 1035 then only the 1035/1420=0,7288 this to the regime of maximum power, it should be much better in the scheme of torque, always referring to the previous example,
1910/4*2,18*1.2928=theoretical value 1345, real-1172, therefore, almost 87%.
But then each engine will have its returns, and the fill depends on many factors, type angle of junction of the valves, shape of the inlet ducts and so on

1600cc/4 cylinders = 400cc per cylinder. 400*2,7=1080

multiply cc x bars where did you get it? sure that is right? seems a little too simple....

I base, I see it so: we take I am blessed afr of 14.7. each mg of diesel fuel needs 14.7 mg of the air. I want to burn 80mm3 that are *0,85= 68mg of diesel. the multiplication x 14.7 = 999.60 mg of air .
Saw that on the damos edc16c39 we have the unity of the mass flow of air expressed in mg reasoning on this unit of measure....

[Errecinque]

And, as the BP of the map lambda of this delta, we arrive at 1000 mg/hub to 68mg of inj (80 mm3) of the BP does not need to change it.

You are going in a loop with the calculations even if you need to understand them thoroughly.
The next step I would say to go to the definition of the map view bp at least for us without winols start the challenge...
Especially the nm and degrees should be defined that I have not understood it..

Begins to look at maps lambda as we have already said. Look at the axes of the Bp on the first (Y) have the value of the RPM on the second (X) you have the mg/hub that reads the maf. On the curves (Z-axis) you have the values, with conversion to 0.001. I know that the value 1 on this axis, you limit the Iq to the ideal value of Afr. In this case, holding a 1 in the lower right of the table we should be able to inject all of the 68mg inj (80mm3). So let's try, let's begin to moddare, put a 1 ( or 1000 depending on the driver ) in the table from the middle of the y-axis and the middle axis x in the then and email the file. Then we go on with the other maps to inform the ecu that we want to inject 80 mm3

On this, I can tell you one thing for sure 7000 on The bp is 70 mm cubes. but you're going too far. First we must define how much air you must read the Maf To Inject 80 mm cubes With a afr of Say 15. The BP 80 them climb after

errecinque not to contraddirti but to understand more,I am hooked to the speech and as far as the 7000 on the bp, according to me, are not always and only iq,if you go for example to look at the map rail pressure you can also see them in the bp to 7000 but in this case we talk about pressure diesel is not the amount that you entered...that's why I was wondering how do you define that the map we are next without a driver... it gives a look at the address 1FB83A and check the bp of this map

I am preparing the file, I do this change to all the maps the lambda?or all 4?
