the council mapping

[max75]

Hi everyone I would like some advice on how to give the right increments on a grande punto 75 hp..with fap....I know that you can't? overdo it otherwise problems to fap...that little push in the pi?..where I can act....thanks

[max75]

Pu? suffice touching only the limiters..exclusion egr...I saw that I have to work only in 2d, why? I don't have the drivers for ecm titanium...but not ? a problem

Hello it doesn't matter that the car has a DPF, you can get the same great results.. on the inj-time stay with a percentage of 8% on the entire map, the rest you can do as you wish

[max75]

Thanks.
I've reassured. ..

Change of 8% across the map of the injection times, I find one thing very wrong. Indeed, on these ecu injection times may be left in the original if you do not have turbo plus.

Of course, you can keep the original, by changing other things in the map, can you? increase the amount? fuel injected, keeping the original times, wrong what c'? according to you?

[jacktheripper2]

That modifying them without looking up the references, the control unit does not know? never the real deal? injected.

you pi? clear as references, do you mean the break?

[jacktheripper2]

You exact. Without raising the break point the ecu is not what happened? never the real deal? injected. In addition, since the injection is longer than the end of the same sar? the further from tdc, and then the consumption will be higher, but why? the ecu take? as a reference the advance for a certain amount? and in truth? ? more to the change being made at the time without changing the axis. Instead of leaving the original times, or changing the axis the controller will go? also, to get the right reference to the advance thus leaving consumption unchanged.

Your reasoning ? correct, but this is for a map soft where you want to play on the consumption

[jacktheripper2]

Watch I play with power consumption and performance at the same time, in fact, I have a 1.9 with 270 hp that going to 120 is fixed in the 3.5-4 l/100km. :D

[max75]

So if I want to lengthen the time without updating the break I make a kind dinganno to the ecu ...but really? you can get results.?

[jacktheripper2]

The results you get them the same of course. ? always the time of the injection to decide the amount? injected only in a case of deception, the control unit in the other the inform

[max75]

A good map would be to increase the time related to the quantity? of diesel by updating the break +the pressure, diesel, unlocking all the limiters...cos? it was a rational map. .
Right

You exact. Not necessary to modify the injection time up to when you are in the range of the original which is usually ? of 80mm3. The quantity? injected, gets out of the Driver's wish and limiters various, and at that point the ecu is the user? a single injection times longer to deliver the deal? request.

[max75]

let's say that the way most convenient for a matter of time' before to fool the ecu without doing many calculations ? the reasoning...the second ? that is a bit more processed, but you get great results....each his choice.

[everyname]

Therefore, the injection timing of the original are fine as long as the quantity? injected (premium) does not exceed the maximum value of the axis of the map of the times?

the discourse ? that if we take a greater amount of fuel we need to see if there are the right times...vice versa if we have a longer...

For the right times you mean to say not to prolong the injection too over the top so as to avoid waste of fuel and consequent fumosit

[max75]

exact....

[everyname]

Excellent, thanks for the confirmation!

I make another account, since the map of the injection timing "this act"? correct to say that the actual pressure at which the diesel fuel is injected ? defined from the time of injection and the quantity? injected, and then the map rail pressure only indicates the limit values?

[max75]

if you want to inject a certain amount? of fuel without times increase the risk of having an increase in temperatures....to make that this does not happen, you can increase the rail pressure...

[jacktheripper2]

If you increase the amount? injected also leaving the original times these will stretch from you to be able to precisely inject what to ask. Of course, this happens up to the maximum reference that we have on the break point of the iq in the map times. On the 1.3 mjet for example, the injection times are calculated up to 65mm3 and 1800 bar? from the original injected 42mm3 about at the bottom, to go down to 35 to 40 to 4000 rpm. Raise the time you may have results that are truly amazing. On a 1.9 mjet the highest iq ? 65-70mm3 about in low-and 60-65mm3 to 4000 rpm, for? the times are already? calculated for 80mm3 then, also, you may have good results without touching the times why? injecting 80mm3 to 4000 rpm are already? almost 20mm3 in pi? from the original and can you imagine the cv are already? out of several if it is given the right advance.

No, wait, map injection timing has as axes the deal? of diesel fuel and the pressure of the rail. The map rail as the axis spins and quantity? of diesel fuel. If you try to do a simulation to see what happens with certain rpm and a certain amount? you realize that the term tends to a fixed value. The map of the rail ? a map goal

Explanation very clear.
A couple of questions: if the maximum time allowed for the injection is not sufficient to inject the deal? diesel fuel demand, the fuel injection it would be interrupted, leaving the unit in the "embarrassment" do not know how much he actually injected?
Given the two examples that you have done (the 1.3 and 1.9) c'? a method to define the maximum iq that ? can inject with the time indicated on the original map? or vice versa to calculate the actual time required to inject a certain iq?

If you try to do a simulation to see what happens with certain rpm and a certain amount? you realize that the term tends to a fixed value. The map of the rail ? a map goal

Then ? the duration of the injection to be defined by the pressure and quantity, of consequenta the map of the times contains the limit values of the durations ? correct?

[everyname]

if you want to inject a certain amount? of fuel without times increase the risk of having an increase in temperatures....to make that this does not happen, you can increase the rail pressure...

If I play well, seen that increasing the pressure allows me to reduce the duration of the injection, this means that, in general, the temperature increase ? caused by the repeated delays in the injection too over the top?

[asdone]

Map the times says: I have the rail to 1400 bar, the driver is asking for 50mm, so to have this amount? you have to hold the injector open for this time.

Ok, got it. When you speak of simulation do you mean to say that c'? a software x to do it?

[max75]

if we increase too much the times we find ourselves inject too much after the tdc, so it can indeed cause an increase in temperature..

[jacktheripper2]

Do you say that ? a good rule to not finish the injection over 10 degrees Atdc. In my opinion for? the one pu? go well on the tdi because? I on the mjet I have always seen that makes it better to finish the injection the pi? close as possible to the pms. Enough to see the original from com'? the end of injection to realize it. Without giving advance the machine becomes more angry and less linear, losing? at high rpm if the injection ? raised quite high when compared to the original, giving proper advance instead, you can make it less sharp, but with more shooting upward.

[Danny]

Quoto Jack.
To down stock, also loads better to the pressure of the turbo, but the top tends to fall much more? quickly, but manages to remain constant anticipating a p?.

[gionag]

the rule does not exceed 2/3? of advance ? valid for any regime ? at the bottom I could give more? ?
