View The Full Version : A3 8L 130hp 1.9 tdi DISK + changes
Hi to all guys...
I have a a3 8l, the first version, the model injector pump 1.9 tdi engine disk, I made changes below, as an exchange of the turbine 1749va to 1749vb-derived ARL (golf 4 150cv/ibiza cupra 160cv),
and I made a map...
For the map, I reasoned thus: as between the motor DISK and the ARL, it will only change the turbine and IC... why not copiarmi the values of the ARL on the ecu of the DISK?
so I copied the values of n75 + boost limit map + target boost + smoke map + drivers wish...
Then I followed the guide that is there for the file of the EDC15...
and then I changed injector duration and start of injection...
the car is fine, but know that it is VERY sluggish from 1500rpm to 2300rpm, right where the DISK was felt with respect to the ARL... and then when I'm in the shooting, known in the gear shift that the egorazione begins to undulate, in a sense, pushes at times, has a loss of power random...
I ask help to you on the logic of the map, or if you go rebuilt from scratch.... important thing I need to know this:
since the turbine is of the ARL is to just copy the map n75 of the ARL, and then paste it on the DISK??? or is it better to work on the original file, without copying anything from the arl?
Attached my map ori with the one I have moddato and also the file where I have followed the guide on how to change the EDC15
are not expert like others but I think from my point of view, not vabbene do everything from **** with ori ...
known holes in the map, for this you go wrong ...

thanks for the response,
could you kindly tell me where you found the holes in the map?
injection split and turbo pressure at least from what I interpreted, I repeat I am not an expert .. so I could be wrong ..
I understand what you mean, there are some points where there are negative values, what is effect of copy and paste, on the ARL there are points that are below the 0.50 mg element, but refers to the map in smoke...
turbo instead, maybe because he has to work in that way, I don't know... I just did copy paste from arl to disk, and then processed as in the manual....
yes, but as I see it ... in addition to the lower increments as you say I see the holes so I would not like the two files are not identical because from your description of the car ... looks like what I'm seeing .. as if arriving at the most at times nothing fuel the same thing for turbo pressure .. may be I'm shooting crap, but according to me ..
you should anyway take the gold and make **** .. advice to inexperienced ... are in the study phase ..
ditto, I also study by quite a few years...
anyway the car gives me a feeling its not empty... as if you affogasse... would not that be the flywheel or the turbine to sti games... because from original something like this...
if is also the original so ...well then .... I don't know
depends on how I leave the clutch, cause I'm game going to strokes, otherwise, go with a cannon shot...
then one other thing that I wanted to understand... is it right to change the advances in fuel injection and duration of injection in that manner as I have done?
Sn with the phone and just drive, Click on my name and I will send for and **** that I send them to a friend I get them to see him if sn is well done ...

Ok, thanks.

And excuse me ...
can someone help me to understand the logic of this map??
if the engine mounts the turbo on the ARL, it is correct to set the from map the original values n75 to the ARL, or is it better to leave the original disk?
listen to me wait anyway you answer someone, but I will say leave her...
the machine we told you yesterday that you go bad enough ... leave her and work on that .. and solve all the problems ... except that you want to await an advice from some expert ... then go for it I personally I'll recommend this ,..
the machine goes wrong, both from the original to be mapped, with both n75's arl is with n75 of the disk...
the my problem is to understand how must work this turbine that I have mounted,
the map n75 controls the variable geometry of the turbine and is made following the flussometria of the same...
to the reason of logic, it is a good thing to adapt the map n75 of the disk to the values of the ARL, this is because the base is identical, the cams are identical, the injectors are identical, only changes the turbo and ic...
that said, at least I know for certain that it is not a problem of the map but it is a physical problem, maybe a westegate too long, maybe the flywheel and clutch too consumed, can be anything, but at least I cast out the doubt and know if you must work with the values of the ARL...
it is capable to have said some bullshit, only the experts could get myself in the doubt, but I do not understand xk do not respond...
oh well maybe .. not connected .. for this do not respond
anyway .. the units are also identical right or what to change ?
oh well maybe .. not connected .. for this do not respond

then, ****llo of the map only changes the turbine, n75, surge, turbine, map, smoke map, torque map and pedal (rightly 30cv in most normal that change)...
duration of injection are identical, advances injection identical...
to ****th e physical engine changes the turbine and intercooler, the electrical system is identical, the control unit is identical as well,
then don't go
if you go, we can try together to work together on the ori both by inexperienced and then try it what do you think anyway by light increments in such a way that does no harm, of course .. what do you say
if they change these things that you said we work the original ..
perhaps you don't understand... it will only change the part of the management of the turbine, which is of course different...
for this I thought to copy the values of the arl on the map disk...
yes I understand but according to my taste to begin with then .
limiters couple too many increments, which then are different you must give them all the same type from rpm 551 4800 from the values all the same example you decide that you 15 percent ? 15 percent from 551 to 4800 no different values ... then turbo pressure you have from 50 to 100 load 1500 at 4746 rpm from the that I know as 3.5 percent , without holes .... arrich in acceleration parts from the 50-load to 100 1218 rpm as 15 percent injection is zoned from 31 to 100 load from 1260 rpm to 5355 ditto goes' type, I'm beginning to think so, the increments ... that's why looking at your gains, I will say that I do not like ..
you understand .. ? I don't know if my reasoning and correct, but anyway, I mentioned (as I do) and more or less I am fine ..
I map I made with logic, reasoning about the demand and the actual...
do you work in a percentage, I've never worked on a percentage and not work ever in percentage...
is there anyone who does it but to me the map is made to percentages or don't like...
the limiters torque you can give it how you want it, you have to see if the clutch bears the load, do as
let's say I have 60mg from 2000rpm up to 5355rpm... admitted and granted that the physical conditions of the engine sets allow, you have the right pair, and horses, many horses, then you have an extension that you would not be doing the map percentage...
I do not know with that logic you do the map, but I, I rely primarily on data calculated...
type, map the flue gas, the original 2000rpm ago 1051mbar with max 59mg, it means that someone is providing with a ratio afr 17.82 around... ergo, if the limiter torque by 70mg, you need to edit the map smoke and bring it over 70mg, type 73 or 75... we pretend that we set 75, go, moved the breakpoint to 1335mbar...
same thing with duration, map, are like stairs, if up to 60mg have 28.5 degrees, 70mg, you need to have 33.25 degrees, must be calculated with mathematical calculations and proportions...
maps muzzo not if they are...
they say that the car remapped it is normal that they do smoke, it is not true at all, must not smoke, otherwise all original car with the same engine block and cavalry different, type, 130hp and 150hp, 150hp should smoke instead of not smoking, so...
I don't know if you caught my thought, but I think so
look I've specified since yesterday evening I am not an expert and I can also make mistakes, maybe say something anyway .. at this point open a new post and this will delete ... I have tried to help you specificandoti do not know if it is right ... but anyway ...
of course, I am also of the opinion that a machine that is mapped must not let the clouds of diesel but I miss too dry is not good but vabbene vah
it is a forum and us helping each other
look in this annex, there is the guide of how to map the tdi...
in addition to this... it would be useful for the professionals of the sector could maybe answer...
map a engine all original is ok...
but in the case of people like me who switch to a turbo bigger, as it must do to adapt the mapping?
how do I change the N75 on an engine that has been changed the turbo?
I with these the ecu I prefer to use VAG EDC15P + Suite..
you will immediately notice that the ECU has nothing in common with the EDC15 common rail
Watch I have not seen the map, but the two things I can dirtele..
First the injectors 130 are much smaller than the 150 guaranteed...
For the n75 before I go crazy and adjust them you have to check physically the adjustment of the wastegate then recalls that the maps n75 in the vag work in the opposite....

Hello munro...
listen I the injectors of the arl and the disk I I, and I can tell you that they are the same, changing those of the bpx, but the bpx may also change the camshaft and other...
for the map you have to see it first thing if it goes mass, that of the arl in the disk, then to change it you know that 8000 points, the geometry is fully opened and 2000punti the geometry is closed...
physically maybe I should shorten it, because from the log I noticed that I have a duty cycle low, I mean a 60% at 4000rpm... then perhaps go close to a turn or a turn and a half... but before touching it I put the hands ahead,, I can't afford mistakes because then I don't have money to fix it...
Before putting his hand to the adjustment of the wg should try to get some of the adjustments "completely closed" with tot depression for both turbines after which you adjust accordingly.
For the injectors trusted even if externally they have codes that are similar to the 150 mills and more..
"Flow" 550cc against the 450cc little of the 130..and then injecting the less they will do away slowly and the turbo..
anyway, I injectors, I have the original disk...
as improvements there are: egr closed with plates genuine vw,
turbo gt1749vb new,
all the rest is original...
but if I leave n75 original instead, I'm a log, I can see where it makes an overboost/underboost and the fits? not good so well?
type... objective the map in the attachment, I write it do a log, and place him, help me?
so in the meantime, I could say if the duration map and Soi are right...
I wrote this map, and I have attached the log as it involves the car with this map...
could you give me a hand to adjust it?
Hello,
I'm allowed to watch it because according to me there were a number of
things that no way matched
you set the torque to 80 mg while the map smoke is limited to 65... tell me about the n75, and then you have also modified the duraction, and you left ori the soi?
I've double-checked but at least on what I see has been set to 80 before he was set to 75 from your file.
The times I've modified to increase the amount of fuel, and the soi I put gold because I believe that the cause
the ondulamento that constatavi is that, before you change it I think that is better to see if you smoke.
N75: I increased the values for a longer duration of the peaks (at least this is what happens to me)
look at the file in attachment, the edc15 you change... you have changed my map but yours is a little out of logic,
if you set a limiter to a torque 80mg the car will never give 80mg because the map smoke you are limited to 67 with 1051mbar of air six to 15Afr then sophomore alex len chipped in like a locomotive...
have you worked on a percentage, you have given 14% on the map smoke, but you have not moved the break point...
also the durations, do not do so, because if by 32 degrees, you need to change the starting time of the injection where you have 25.8 degrees, otherwise it will inject diesel after top dead center...
turbine have given 2585mbar, but the limiter is at 2400...
for the n75 there is a problem, because I up to 3000rpm is underboost, after 3000 is an overboost... with the mod that you did to me you should do it all in an overboost...
The limiter Turbo I forgot I realized.
With regard to the mass of air actually sucks in ca. 1230 Mg/Hubs, and
80 mg (not 67 mm3) have an afr of approx. 14,7, and how can smoke? I will ride with my
12.8 and do not smoke.
For the SOI I saw that you said you are out and inietterei after, I apologize.
P.S.: I all the BP I upgraded to 80mg because they were put on 75mg. According to me all the BP
are expressed in mg and not in mm3 and then in reality as I saw you have raised the lim.IQ 80mg
then I deduced that I wanted to inject that amount, this BP that you say that I left ori I can't find it
because all the BP that you did have them selected and increased and the rest I left as you have left in you.
Could you send me a screenshot? at least I can see if really I have forgotten?
are the usual maps of soi ranging from -20° to 90° temperature...
then the duration, you do not in that way,
type max you have 60mg, you want to take 80mg, you'll need to move the break point from 60 to 80mg and then adapt the degree, type, if to 60mg have 30gradi to 80mg you 40gradi, calculations done with the method of the proportions...
for the AFR in a diesel it is not as in gasoline, the afr on a diesel is 16, on gasoline of 14.7, a diesel engine 16 of the afr smoke type locomotive... noting that the last audi in the circulation have afr 23...
the map is expressed in mg and not mm3,
from the map the flue gas to adjust the afr base, the x-axis is expressed in mbar, the y-axis is rpm, the z axis of the mg, 1051mbar and 60mg it has 17.5 of afr, and do not smoke, set it to 16, and give 65mg to 1051mbar smokes, try it out for yourself...
then it all depends on the logic of the map, and there are those who map to 80mg on 1051mbar, but then turbine has a request 2900mbar and do not smoke (classic example of a tdi with 2260vkrl, smoke just fin when the turbine is not in full load)...
You can calculate the afr with the pressure..
The variables are too many type, temperature,density,yield the adiabatic and volumetric,etc...if your ecu works in the map function, the increase in map smoke map based should be given in percentage...
For the turbo you could try to mount the wg 130 on the turbine 150 without touching the recording is to see how it behaves..
it's getting worse, with the westegate of 130, has a peak at 2600rpm, is above 200mbar, and then swings... it's the same thing with the original map with modified map...
Then you have a problem of registration...
Before you go crazy with the maps n75 you have to do a proper recording..
If I remember correctly, with 0.5 of depression, the wg should be closed..
I do not remember, however, the recording of the end of a race, the one with the allen screw..
It seems to me should be 1.8 mm..
But I'm not sure..

with this file, it behaves so, watch the log...
Momentarily I have no way to see your log..
Are out-of-home is I don't have the PC with me..
actually, looking at the map of the ARL under 2500rpm the values for duty cycle are lower... ergo the turbine is more open...
