a greeting to you all!!
I wanted to ask you a question on a edc 16c8 of which, or change the maps pedal,rail pressure,turbo pressure and the various limiters,before changing the map, the amount of fuel injected was about 68, with the changes I almost 76 now my question is this: I would like to change the timing of fuel injection, but on the axis of the quantity of diesel injected into the maximum is 80 then if the real value do not pass you do not need to touch them right??or has nothing to do??I hope I explained!!!thanks in advance........

if you want to inject after 80 you have to update them if not c and need because they're already calculated

If you want my advice ? just to touch the limiters iq

hello angel, thanks!in practice, you're telling me that if I want to inject over 80 to touch them, otherwise, no!but even if I do not pass the 80 at full load at the same rpm and rail pressure, the quantity of fuel injected is higher than the ori !example:in gold or 1000 bar rail, 50 mm3 and 935 us, if I touch the dw, and limits the quantity of fuel injected will be increased to 50!!!then the time must be up-to-date????right??booo I don't know how to think!!!!!!

There are very specific points in the map that belong to the out driver to raise the limiters diesel if you don't touch them, you'll never have ir? fuel injected as well as what ? standard

the limiters of diesel out of the drivers I know them to be alzarel'iq,ilproblema that I can not find a line of reasoning with the times...
angelolsp

When you touch the driver wish to increase the torque demand, l ecu sees how much diesel we want to x the right pair, and where before you had 300 nm x say, and corresponded say x 60 mm3 now you have a 350 and correspond to 80, and then use the time to 80 if you want to 500 nm ke correspond to eaempio 100 mm3), you will need to aghiornare the ecu infarmobdola to calculate the renpo x 100

that is, in practice, by changing the dw the ecu to get the torque demand, e.g. from 300 to 350 nm implement certain strategies, i.e. to use all the maps??? raise the quantity of fuel injected,turbo pressure , rail ,time and advances.....???another thing if raising the iq from 70mm3 them to 80mm3 times are already updated,but if the iq of the port to 90mm3 you have to update it by changing the last line, but after the time 80mm3 is not busted or not has nothing to do???the thing precise would be to change the brack point.........
147q2

if you want to go beyond the value of gold ( 73mm3 of diesel fuel ) have to get rid of the lim iq and if you want to go beyond the 80mm3 you have to rescale the break
angelolsp

if you want to inform the ecu you have to rescale the break if no increases the time by tricking l ecu ke believe ke is by injecting 80 but really? will be more
alfetta80

ok now a little more clear...but the sti blessed break and tell me how it works??it takes some program specifically, or you can also make it with ecm bo I don't know, never seen it done ... angel, I'm sorry, can you explain to me the best factor to trick the ecu??thanks
angelolsp

Then by brak you understand ke map type e and ke are the dimensions of the map if the last break of the map time inoezione corresponds to 80 mm3 l ecu will know ke unlocking the surge has already the calculated times until last brak that 80...now if you want to know ke you want to iniettarr 85 to update the last break to 85 and anke times ...if you want to inietyarr 85 without making it known to the eecu leaves the break and only touches the times calcolandoli and the ecu will always ke are 80 but in reality will be more
alfetta80

ok now, or ideas a little more clear because I did a search on the break and I cleared the ideas!!anyway, I don't understand two things,from the various maps studied speaking of edc16 most, if not all, of the times, not exceeding 80 but they are always aware of why?then nesuuno that tap the map quantity of fuel injected as ever??
angelolsp

welcome to the quantity of fuel injected is not another ke map conversion ke passes the request of ccoppia or Nm in the diesel fuel injected or mm3 and then the map and calculated x 500 Nm or 100 mm3 until they exceed them has no sense of touch
alfetta80

ok!!!clear!!!!!!!for example, if you make a map where the maximum iq and 80 mm3 you time them toccheresti a little bit?or leave them updated as a source??
angelolsp

I would leave them ori..
alfetta80

thanks Angel, you have been of great help!!!

The map and the injectors on the bench you do that by measuring the quantity? diesel fuel is injected (gauges FLOTRON) in mm3/colpo_cilindro for each ****llo rail pressure, at the change of the ET (time of arousal [us]), interpolating and then to have a map that tells you, for the rail pressure present, how many microseconds to excite the solenoid, to accomplish the volumetric flow rate that you need for each injection.

The logic part by the required torque - transformed in mg/colpo_cil required (total between all of the injections of the cycle - amount? pilot and post defined by maps, the relevant q Main control pair) - knowing P rail and the temperature of the diesel fuel (density? diesel) - enters the map the injectors with the mm3/colpo_cilindro you want, and the P-Rail current to determine the ET for each injection.

The introduction ? however, limited by the curve of introduction limit (EngPrt_qLim - for EDC17C49).

If you do not increase the introduction over the last break point of the map to the injectors, I will never have the time, in microseconds, ET al. Those times were measured and interpolated (even more than the introduction limit), then you are +or - of course that by energizing the solenoids for those of us in those Bars, you will have the introduction that you actually want.

hello checchi thanks to you x the contribution!
in this map there are limiters smoke; hence' threshold luminaire top and bottom as we think in these maps, and what is the difference between one and the other??
checchitotiralaleva

Hello Alfetta80, I'm sorry, but what kind of map are you talking about?
I know there is the map smoke SmkLim_rLamSmkEOM0_MAP (on EDC17C49) in which you calibrate the lambda minimal lower. In transient control of the torque goes up almost instantly the target of fuel to be injected, but the air arrives late (the compressor fails to give you the boost instantly) cos? to limit the opacity? of the exhaust gas (and stay within the limits of approval on particulate matter) you need to calibrate this map who controls the growth of introduction during the transients when the lambda reaches the minimum calibrated. Allowing you to give other diesel only after the arrival of the boost --> air. The lambda minimum when operating in a steady state ? much more? the bottom of the bed. The map smoke must intervene only in the transient. In steady-state the introduction should be limited only by the curve of introduction limit.

hello checchi!!the map to which I am referring is a edc16c8 of an alfa 147 140cv!!conil driver ecm I find these maps the first and limiters smoke; hence' threshold luminaire top and the other limiter smoke; hence' threshold the luminaire bottom I don't know how to interpret that... I'll give you a screen
checchitotiralaleva

Unfortunately, I still can't download attachments...
However, I think that for the threshold lambda lower limit I think it might just be the map smoke that I described to you before.

Ciaooo

Lambda upper limit I don't know what might be...

you checchi and a limiter smoke but the problem is that I don't know how to interpret it and one other,then I'll give you an example on the map lim fumusita' (top) I 2500 rpm 1050 mg/hub that should be the quantity of sucked air and the remaining z-axis'm 1080 lambda,the other map (below) is identical!!!now according to the rpm and the intake air change what?????????those 1080, what is it??? ratio lambda equal to 1 of 1????this applies to gasoline, not diesel!!!!!!!!!!!!
checchitotiralaleva

Hello,
1080 definitely not ? even the order of magnitude of a lambda. At least 3 orders of magnitude... 1.08 could be a sensible value. Just because? a diesel always works the lambda-very lean (high), 1.08 may be a lower limit.
Unfortunately I have no familiarity? with the ECM, we only work with programs ETAS as the Inca, in which you just use variable names of the original BOSCH. For me the map smoke = SmkLim_rLamSmkEOM0_MAP, and are sure not to make mistakes... I don't know how the ECM-face associations between its conventional names and the variables contained in each software...
I can give an example of what is meant normally for the map smoke:
The ones that I have ever seen I are expressed in x -> rpm, y -> mg/hub of air, z -> lower limit Lambda (Lambda = alpha/alpha flow down. then: Flow rate air flow rate/diesel/14.5).
As I said, the map smoke ? the map is made to intervene in the transitional limit l?introduction of diesel ? limit opacity? at the discharge (emission limits on particulate matter).
We put the case that the engine is spinning at 1000rpm-120Nm, and instantly the driver gives a kick to?throttle (100%) to accelerate the motor against a constant load of 120Nm.
The engine will have? deliver a higher torque of 120Nm to be able to accelerate.
At the end of the transient, the engine will be running? in the limit curve of the introduction of diesel to 120Nm, the speed? maximum rotation such that ? can still develop 120Nm.
All?the beginning of the transient, the engine is turning at 1000rpm-50Nm using 900mg/hub d?air and 20mg/hu of diesel fuel (lambda current = 2.9)
In the map smoke ? been calibrated a lambda limit to the point 1000rpm-900mg/hub air of 1.05 (quantity? limit diesel fuel from the map smoke -> about 59 mg/hub-diesel ? diesel lim=air/lambda lim. / 14,5).
In the moment, instantly you will get to 100% pedal, the diesel is porter? immediately 59mg/hub while l?air start? only after to grow (when will arrive? the boost?).
In every moment of the transient, the ecu knows the rpm, he knows the?the suction air, know the lambda minimum calibrated, and then recalculate the amount? limit diesel point to point.
At the end of the transient, the boost will be? the load, the motor will be running? at x rpm ? 120Nm (35mg/hub diesel ? 1150mg/hub of air), the lambda limit of the end point may be 1.35 (quantity? limit diesel fuel from the map smoke -> about 58 mg/hub diesel).
The calibration of the lambda limit must be made by finding the right balance between opacity? maximum allowable speed? of the transient request.

The calibration of the lambda limit must be made by finding the right balance between opacity? maximum allowable speed? of the transient request.
So much more? the lambda limit ? the lower, the more it will be? the quantity? diesel fuel that will be? can inject (TRANSITIONAL! ? In steady state there is always the curve introduction limit) but ahim? also, the greater the sar? the sfumazzata?

And, of course, much more? fast sar? the transitional.
The improvement of the speed? in the maneuver of course, do not ? linear with the reduction of the lambda limit, also an excess of diesel pu? worsen the success of the maneuver.. Even just from the point of view of performance it is therefore necessary to optimize the value of lambda limit, not simply sblindare the map... If I put 0 as lambda minimum and I have a large turbine (slow to give me a boost, and then the air) affogher? the engine!

The first has to the axis, rpm and temp the 2 rpm, and a value in%, but I don't know what.... it is evident from the values that are limiters iq and the third I still don't understand. C'? also to understand what curves to raise to 8000 (if you 80mm3) if all or only the last. Let's understand something together

As written above, the same car that you have 147mj140cv ?3 the addresses of the first two should be the exact ones shown are the beginning of the first curve of the maps. Just before you have the two curves of the bp. The 0e9470 as said not I realized it, not even me. Here I have posted the screen of the first 2 listed.
But I have yet to be confirmed if they are modified in the right way

there should be a third if I'm not mistaken...
switing63

I saw that discussion ? a bit dated, but since I just joined and I am trying to learn anything I of this unit, I believe that the third limiter that you are looking for is 0EBF1A and should be a limiter on the basis of the temperature of the diesel fuel. Get information with pliers and why? I am very novice to? maybe some good soul can? confirm cos? I learn well I some what.
