Hi all, I was wondering if for the newbies like me, there is some study material or generic for edc15c2 (for my car ? what I'm interested in). I know that who ? a professional chiptuning (who paid for the courses and updates) there sveler?' ever and free;
I decided to join this forum because? it seems to me very serious and I hope there are people willing to help others.
what you need to know specifically?
Hello DemolitionMan I would like to learn how to map the EDC15C2.
if you can map edc15c2 want to say that you are able to map a large part of the ecu diesel! and then you're not a beginner! participates in 50 posts and start to read and see what they have done to other users of the forum! you have so much to learn! then read to begin to get an idea .. and then you can start to make concrete questions! none do you serve? the dish served! I think it is also normal.. but no one will negher? the possibility? read the experiences of others and gradually understand more and more.Quote:

Yes, you are right, it takes experience, I tried to dig around a bit in the forum, but I can not even look at the pictures and edc15c2 no I have seen.
Start with the post base maps, then we can help.Quote:

yes, I have done 90% but I would like confirmation if all the maps are good.Quote:

the remaining 10% that you have not done you are turbo pressure and rail pressure, which are the only ones that could go,for the rest all over again.Quote:

those that I have not done I have to address 066D3C, 067020, 06704E, 0670B6, 067300, 074EAC, 074ED8, 076D3C, 077022, 07704E, 0770B6, 077300,07EC12, 07EC38.
and those related to the fap.
Where do we start ? from the torque limiter ?
I agree fullyQuote:

ahahahha.exact.Quote:

anyway, see what I can do to help him.
One of the many systems for the imitator torque can be to change from 1500 rpm and a 20-25% increase phallus and then email the file.
from what I saw in the file already? posted nn c'? only the torque limiter to fix it, but the whole map ? redo it starts to make a map at a time that we give you a hand the advice of our friend msport ? right but then you should refine a p?.
the torque limiter expresses the amount? fuel injected cilclo from each injector in the edc15...
compare files of the same car (same engine) but with more horses can? help you to understand how to increase...
Then , since I made a mess,I put almost all golds except for the fap off, the bit egr,turbo pressure,rail pressure and limiter rail.
I have modified the first torque limiter, i wait for your comments.
Thanks cjack you gave me a good idea,I can compare the 2.2 hdi that fits the C5 and 406 that ? always EDC15C2.Quote:

and as ever, if increases of 50%, the torque limiter, the car does not smoke? you are convinced of what you have written? ..Quote:

greetings
I think, however, there are other limiters for the diesel fuel, as for example limiter IQ right ?Quote:

it should be the quantity of the fuel, expressed in mg ?Quote:

Correct me if I'm wrong, I'm a beginner, do not take me around(do not offend me, but' not ? nice when you are taken for an ignorant by a professor ...)
Then the other factor that could limit the smoke ? precisely, the map of the fumes.
look, I'm not kidding! but IQ had not intended for that! anyway you will not complicate life..! start with the main things! injection zoned , turbo, pedal rpm and torque limiter!then the other things slowly .. the car will smoke like a chimney at the beginning ? normal! then slowly you will understand why? it happens and correct your map! but if you want a course to make the chip tuning ? normal that no one you do? free...!in the forum we can only give advice and opinions.. but not courses ! ..
No quiet my problem ? on the contrary, I do not smoke at all, and I think there is some limiter diesel on the map that I know of;Quote:
Originally Written by DemolitionMan
I assume that the stoichiometric ratio is low, reaching the ir? air from the turbo, but always with the same diesel.
On the various tests that I cat I always empty from 900 to 1400 rpm, and can't get it to go well from 3000 rpm and up.
Now you have your fireplace! at least not complaining + :)! check what I did on the pazializzato.. still missing the air to the engine! and + I touched a torque limiter! check it out!good job
Thanks DemolitionMan, for now, I'm studying, scarichero' your change when raggiungero' 50 messages
In the meantime, I can see your map, I have prepared another.
With winols I found the addresses of the maps SOI(start of igniction) as you change these maps? Or not to touch ?
There are some tutorials on the internet EDC15!
It is recommended that you take a look on them
It was cos? I started and also some files with friends and try to understand
Yes, in fact I'm looking for, I have to say that I find more information in English;
then, the soi maps are the maps of advance of the start of injection;
Suppose I change the injection timing by raising them to increase the mm3, and must therefore anticipate the injection so that you have a better combustion(non-injecting After TDC), so the fuel burns almost everything also diminishing the smoke.
Now I was wondering if I could do less of the map map1 and map2 (ecm calls the injection time) and the maps soi seen that you can' inject more? by increasing the pressure of the diesel oil.
What do you mean by injection zoned?Quote:

The "map smoke" ? a limiter IQ based on engine revolutions and the amount? of the incoming air.
In practice is not to inject too much when c'? a little air.
Right?
Now someone explain to me where does the term "injection, split"?
I found this term in both ECM2001 that ECM Titanium without understanding what you meant...
Edit:
IQ = Injected Quantity
it is measured in mm3
Do not blame those who use the codes ? very normal thing to use IQ, SOI, SVRPL, SVBL, etc..
Beginners should learn first the general operation and the initials are from the s?.
Something tells me that Alientech has not yet learned much, considering that on the maps as the axes of the rpm mototre and the load from 0 to 100%. But from where the hell they take that I'm loading?? Really? the axis are RPM and IQ. And if you want to do a remap as it should, you'll also need to extend the axis IQ to be able to inject more?... vabb? let it go.. sorry for the outburst..
Hello Alex, thank you for your definition of ecm called the injection zoned, the axis of the IQ ? the ramp is just before the map, right ?
In my case, the ramp from 16,00 to 9000,00 (in decimal).
That 9000,00 not ? the IQ but the mm3 of air sucked Right?
Then, we do a p? of order..
In practice, EDC15, unlike EDC16/17, we have the axes of the map just before the map.
Not all of them have axes, but for the most part, the ch? helps a lot to understand the maps.
The two-dimensional maps have two aces, then you'll find yourself a signature byte, which identifies the meaning of the axis, then c'? the size of the board, and then the actual values of the axis. The same thing is repeated for the second axis, and then begin the values of the map. Of course, the one-dimensional maps, such as torque limiters, have only a single axis and then begin the values.
Example of a hypothetical map fumes 3x2:
50222 00002 01000 02000 50996 00003 05000 08000 09000 01000 02350 04420 01200 02600 04800
In bold are the signature bytes, in my ori, all 50222 are engine rpm, 50130 ? the temperature of the liquid cooling system, etc.
Some ECUS have the software very similar, and the SB may also be the same, but usually they are different then you have to find the meaning of your SB.
Italic c'? the length of the axes, the underlined values are the values of the axes and the rest are the values of the map.
The map of the example would be cos?:
rpm ? used to denote the revs of the engine, really? it would be to write to the Engine Speed, measured in rev/min (revolutions per minute).Codice:airflow 500 800 900
-------------------------
rpm |
1000 | 10,0 23,5 44,2
2000 | 12,0 26,0 48,0
airflow ? the air flow measured in mg/impulse. In practice, the milligrams that come in a cylinder in a cycle of suction.
This map, being a map smoke ? a limiter, then the values in the map have the highest IQ.
IQ = Injected Quantity, measured in mm3/stroke. The factor if I'm not mistaken ? 0,01 therefore 01000 becomes 10mm3.
If you want to calculate the air-fuel ratio, you have to have the sessa unit? both the extent and for the air to the fuel.
Easily convert from volume to weight in the diesel fuel, being 1 mm3=0,835 mg.
Cos? you have both air and fuel in weight. My 2.0 HDi, the series goes on a ratio of 17:1.
Obviously it doesn't make sense to increase the values of this map, why? the machine fumerebbe giving so much oil with a little air.
The problem lies in the fact that my map as your see, the axis of the air flow, defined up to 900mg. Really? my, series, arrives to aspire 1000mg safely. By increasing the turbo pressure from 2000mbar to 2250mbar arrival to aspire 1300mg quietly and without too much strain on the turbo seen that ? made to go up to 2300mbar.
Quick calculation: with 1300mg, and a ratio of 17:1, I can inject up to 76mg, equivalent to 63mm3. But to achieve this, we need to "stretch" the axis of this map so that the ecu knows what to do after the 900mg. Why? cos? com'? now, above the 900mg the control unit takes the last known value, and then always behaves as if it had 900mg of air.
Since we can not do more? space, you have to delete a column that we feel useless, move the other to the left so that the last to remain free. Cos? we have the penultimate column that defines the 900mg of the series, and on the last free column, we can define, for example, 1000mg.
For stayed at the column you want to delete, usually the first are the same and are de type, 200mg, 300mg, etc..
Consider that even at 750rpm and do nothing, the engine sucks in at least 400mg, and then you can delete the first column, move everything to the left (map and axis), and define the last column.
I hope not to have confused the ideas, and maybe now you understand why? a map of the flue gas with an axis RPM and other engine Load 0 to 100%, has virtually nothing. You can only decrease the ratio of AFR and make you smoke more? the machine, or to increase only the last column and to smoke during acceleration strong..
If I was not clear on something ask as well ;)
Hello
Thanks Alex.t of this valuable information, difficult to find people like you that as I see you are quite prepared; that helps beginners like me to understand better the map cos? in the details.
the speech is a fold! you've been very clear and I see that you are quite prepared many the fact the theoretical neglect it so much, your information will surely come in useful to many people at the moment are not so forward.Quote:

I'm really glad to have been able to help anyone who reads my posts and I assure you that I'm not an expert. What I have learned I did it for the pure passion in time ****** and I never based on hear-say and about the things easily on the forum. According to me it is necessary to consider how knowledge of the things of which you ? 99% sure. At the beginning you go a bit to intuition, but with time and the tests/errors you get to knowledge a solid.
I advise you to read a document that is easily found in the network called the "Bosch HDI EDC15 C2 Injection System and Particle Filter". It is a pdf of the Citroen, but that of course also applies to the Peugeot, which explains the operation of the whole system. It is based on the 2.2 DW12 HDi for? the operation ? the one for all the HDi engines.
I hope that you are familiar with the English. I learned everything in English, reading different documents, and writing on the forum in English, where there is a lot of people willing to help you a lot.
Hello!
You can find here the document first: http://www.sendspace*****/files/vuh0w3 :D
Thanks alex.t your contribution ? outstanding... I did not understand a lot, at first reading, but after 3/4 times I have come to understand the concept!
