View The Full Version : mapping tips and advice
Good morning,
then, I present a mapping made some time ago by a trainer that the machine in question is my bravo jtd 105.
I would like to understand with you if it is done well or not I'm attaching the map ori and mod and tell you what according to me is not the right way to figure out if I'm understanding some of what I'm learning!
then I list what I think is done wrong in this mapping.
-the limiter rail pressure has been left original.
-the map rail pressure is increased and exceeds the values of the limiter of the press(and according to me this could lead to a block, and/or power-on light engine) and it was edited in my opinion evil with increased values a little without logic
-map the injection partialized was increased only towards the max load and was increased according to me some nonsense
-the maps parzializzate map 1 and 2 were made different, and the increases seem to me to be made a little haphazardly
on map2, there is an increase in the low-load to medium engine rpm of more than 30 which in my opinion is useless and could make the machine scattosa.
among the other off drivers there are other increments that, however, I don't know what they are.
Then, The map rail pressure you have increases that could be wrong or better non-linear and however, you should also increase the limiter in my opinion. The map that you indicate as an injection choked, is a limiter in the flue gas, and has not been altered evil. Other changes outside of drivers that you say, other maps. In all this, the car as it goes? The map is not much exaggerated, and the car should go well I think. Tell us.
then I speak from ignorant on the subject and is just to see if my logic and right or wrong I do not say that it is made badly I want to learn to understand if it is done at the end or no, and what I wrote is my interpretation! definitely not exact!
however, the car goes well and ****s performance has increased dramatically the frperò there is the original does not hold the power and slide also from the new smokes like a Turkish but I think it's because the turbo is a solid and is original has not been touched!
you become very sensitive with the throttle in fact, if we do not make a little hand touches l throttle snaps! and then, at times, into shooting the machine the light comes on and goes off and this I think is due to the pressure limiter is in the original.
I sincerely I saw some holes that I don't know you're are correct that at the same load and increase rpm on the map ,now I can't remember what I have to go to review, the values in a box, descend a little, and the one after riaumentano I don't know if it's right so pero in my opinion, my might you are a hole, maybe in the guide does not feel pero
The car smokes and slips the clutch, and because the time of injection were loaded a bit long. It is not for the turbo fixed geometry. You can make maps that are better, and who do not smoke and the clutches do not slip. Also the torque was increased even at low rpm already at 400 rpm to tell you.
the injection times which would be according to the ecm?
I think I have them out of the driver as well as the map of the couple.
on winols I don't have the damos for this map, and even I can see.
then a curiosity, but the split map1 and 2 should not be increased in the same way?
I would like to make it a little better this map, according to me, we can do better, how is you that say egs?
zoned 1 and 2 are the injection times..
com s if you can't say the never is the map sucks... I do not like it nothing I'll explain why...
starting from the beginning of the file I find the egr is not closed....lim press the turbo is not touched but the press turbo more forward...
lim couple completely redo it and partitti from low rpm even increments sostanziosisi that only serve to stress the mechanical in addition to the fact that it is toccatto the axis spins de limiter the same I do not understand why..
injection split or the lim fumes made to a member of the canid...I have the increase, following the logic of the afr or not you tap your ...then injection time map 1 and 2 which also leave them with increases driven already low-iq and low-pressure rail... the only thing good in this map, and press the rail but saw that you wanted to raise the lim has made another membrata...I repeat for me is to go to the body then I don't know...
thanks munro certain that you can have your say, I am all ears :P.
however, to me, has appeared so a little without a sense of logic now I'm not an ace on the contrary they are less of a bad one is evident but I would have put at least the lim. the rail line with the rail pressure and map 1 and 2 I would have them made the same.
Looking at the map on 2D graphics, however, do not seem so badly seems to be made better, there are some line a little crooked but by them not seem so excessive and even too hurt pero looking at the table it seems to me wrong.
however, the limiter turbo pressure and turbo pressure I have not found and, anyway, it seems strange to me that there are as it is a fixed geometry even if we were to change them I think does not serve much given that the unit is not going to adjust the pressure.
l egr, however, I closed with a plate, as on these cars the light does not turn on, it stores error but do not turn on the light.
the limiter flue gas in practice, what needs to change?
and just out of curiosity, what software l have you seen it?
l' I view with ecm...the lim smoke should be to limit your quantity of diesel injected....
the press turbo and its lim, and true that does not directly handle the turbo on this car but when it comes to consistently improving the iq has also increased press turbo because there are more exhaust gas to spin faster the turbocharger... in your case it is even more as the person who made you the map goes to trick the ecu and thus you have certainly piccate press turbo and that is why you raise it a little not to have problems with recovery, or lights and various lit...
on these the ecu for a change, more than good enough to unlock all of the limiters of diesel and without even touching the timing the car goes more than well...
the maps tmpi injection are already calculated to inject up to 1500 bar to press the rail and 70mm3 with turbo and clutch gold you are already at the limit with this diesel...
not can I view it, but from the cove is described........................lim of torque at 400 rpm sense,is the classic map from the gas station-preparer,has touched the injection time because he can not unlock everything so it makes smoke.............
follow the advice of munro.
for the turbo pressure can be changed manually via the wg if you have the need...
for the clutch I suggest you change it apresindere,at least disk and clutch pressure plate reinforced
now I'll try to edit and I will upload on the forum to discuss it with you, so beginning to learn something!!
Frank to tell you the truth this is what we made was a preparer of rally cars but then I discovered that several machines that prepared scocciavano turbo and a few of the engines.
however, the turbo I think I will leave the original so charged to 1.3 bar I don't know why I have mounted a pressure gauge to the pressure after the change.
munro to the surge of smoke I found your post where you explain how to intervene.
and then just to see if I increase the limiter, smoke limiter and torque limiter, press the car already runs better?
solution if you do not increase it pressure time?
a curiosity, but the map turbo are you that you know the addresses or you will see ecm? because to me does not make them see.
the other curiosity with the map mod ecm does not find the drivers I think that is normal because it changes the cecksum and do not recognize him right?
the project,if it is not a problem,can you post the details,so I can make an account too?!?

then project to the turbo is as I have explained to you I...you have 1.3 press the turbo without having even touched the turbine because you have more fuel in the combustion chamber which produces moolti more exhaust gas to spin the most velocemte the turbo and more turbo pressure....
in addition to the maps that you said the ecu-there are other limiters that stop the diesel....don't worry we can find them together...once found and set, because the map times are already set, you can avoid to modify the times at the most, only the press rail since the axis stroke of the press, and climbed from mother fiat up to 1500bar...you then still have to do a log of the press rail to see your pump as is...but we get there after.. the map turbo in the ecm can not see it but your trainer modified the find to 07F7FE....the titanium and, in general, the ecm recognizes only the original files..
ok perfect, however, then I carichero the original map and do a log cn all the data, press the rail,maf,injection time and quantity of carb so as to have a starting point and figure out what exactly I changed and how much thing that I think we can understand by the map, but slowly I'll get there even I with the experience.
however, in summary, I start with the close out the egr because I find that if I'm not mistaken it should be at the beginning of the map,and then proceed with the increase, the limiter of the turbo so as not to create hassles with the light and recovery.
the address that you have given me and of the turbo or of.his limiter?
I'm sorry, munro I was making an argument on the basis of what you told me,correct me if I'm wrong.
you told me that the timing of the injection on this car in config golds are already sufficient to withstand a pressure of 1500 bar.
so according to what I know to let go of most of this diesel needs more amount of fuel and air of course.
now since the times are already enough to me it would be enough to raise only the pressure of the reasoning that I did is the following
with the same injection time if I increase the pressure I results in an increase of the injected quantity, is it right?
so let's say that the timing of injection should be increased only in the case in which the pressure with which I would like to work on a map are not sufficient?
if I increase the pressure open is also slightly time however would not be an increase in ****s performance?
if you don't unlock the "limiters" the quantity injected at each cycle is always the same!
now, I can't frank just come home give them to you I'm sorry!
the limiters are always the ones that I do not see?

you but the speech is a little more complex than this...
the ecu interpolates in continuzione the parameters in the map to give you unacerta iq...
now let's suppose that you retrieve from the map 65mm3 to 4000rpm ok?
the ecu what to do, and goes to interpolarsi in the map time(simplifying a lot but there are several other steps) to 65mm3 the press rail on the right and the injection time suitable to you to give you that date iq...
now if you increase the press rail, and notwithstanding that your pump rail is in great shape also taking the press at 1500 bar the ecu difficlmente will give you the pressure for iq, low or limited by the ecu itself..
for frank85 hw and sw project are 928 212
ok, I'll have to still unlock on the blocks to continue successfully!
now it is only me sti cavoli blocks!and unlock it, and then get me a map to oc working on rail pressure and wanting to go up on the limiter smokes!
the times it would be better to leave them gold, you say?
trusted with the clutch and disturbs ori's best to leave them ori the time...
make a test map to put it that I say then how to fix it and unlock it..
thanks munro!
I took a quick look and I found(if I'm not mistaken) of the limit 07b270,07c54c,07fe02,iniez prov 07cd32,07cf58,lim rail 07edb8 for now.we see more in the.......
then
07b270 is not a limited is the map request iq to the bosch engine
07c53c even he is a limiter and the map duty cycle of the pressure regulator rail
07fe02 is a map related to the glow plugs, do not touch it..
07cd32 are the injection times
07cf58 and the rail pressure request start-up
07edb8 is the limiter rail pressure as a function temperature diesel
ok I just put all the work is the load!
some maps for you..
079abc pressure turbo
07bc22 iq limiter (10x1)
07bc5e iq limiter via fuel temp (6x6)
07d180 and 07d228 lim press turbo (1920), you can touch them if you want
07d2cc advances for the time being not to touch them
07fa74 lim press turbo function press atmospheric
07fbd0 iq limiter on iq (16x10) set it all up to 70mm3
o7f7fe
is the ecu a bit dated and there are no damos on this it takes eye frank
what are you talking about frank?
nothing happened....
I am quiet I have no problems
not get not even you....
what are you talking about frank?

I am quiet I have no problems
not get not even you....
munro will not pereoccuopare I know that you are a correct person and that you don't have problems(other already they will send me)
I wanted to see my eye where he was coming but.........and now look you to learn.....
guys, however, i offer you my compliments, is a pleasure to work with you are people who are truly very humble.
now coming back to us!
I made my changes I saw that you put the limiter iq that you say that all is set to 70mm3 then, in theory, the logic that I implemented is useless for the moment because otherwise still limited,but we will proceed in a little time.
-then I modified the limiter for flue gas according to my logic,judges according to you if you can be good let's see if I reasoned well.
-I have changed the rail pressure and as I did so I passed the very bad idea to linearize the curve does not l I did it in the map, but I attached a picture of what came in my mind.
-limiters of the pressure I increased a bit more of the map press. rail is always going to be in line
-increased rev limiter a couple.
the increases in pressure are minimal, depending on how I'm reasoning I thought a little bit more still you can give pero in the meantime, let's see if I understood the logic.
you're not there project....
lim couple you could try-most of the time delimited 2mm3 more...do you believe that it will be sufficient to feel the difference?
lim fumes you set to 11 afr you are too smoky....remember that you need to do the calculations, calculator at hand, and you can also set to 15-16 afr...
rail could even dare here, more uses the interpolation of the titanium and from 2 to 5 % more
limiter rail watch it in 2d and see what you have done and na crap....
because you skipped the map that ecm calls arrcchimento acceleration?
what is the driver's wish and the request of heating oil that you do it in the ecu with the foot why not adapt to be able to apply the ceiling in the times of 70mm3?
committed some more project
the limiter iq is not the put I to 70mm3, but you must make you and the 16x10 that is to 07fbd0
ahahahahahah na crap I paciuto :P
ok then I'll explain I have read in the lim. smoke a maximum value of seven mile and broken I thought were 70mm3 at the most suction I have a value of maf is around 1200 so 1200 divided by 70 and I was dating 18 and something I increased to 1000, the value from mid to max and when he was 15 the same thing from the middle to min taking into account a value of maf is a minimum of about 450 obviously I've done something wrong.
scusasami but the torque limiter thing I am limiting myself effectively?
enrichment in acceleration, I didn't know what it was, and I've touched then I would map the pedal and how you should be touched?
however, the pressure limiter I made a copy of map pressure because it would be the coming evil?
are a stress, I know :P anyway I assemble immediately a other
remember for the lim fumes that you in axis, you have a maximum of 1050 mg and the output of the map, and in mm3 and then you have to convert mm3 to mg with the fastore conversion is 0.85....now you're at the 80 odd mm in the map smoke and then do 80x0,85=68 then do 1050/68=15,4 of afr, but only on the position breakpoint of the 1050 mg air you this afr you'll need to repeat the inl calculation on all the break point of the air, looked at the axles and you will understand..
do one thing at a time altrimati it just makes confusion
ok do one thing at a time, I have to apologise but I'm not following you, I on the axes of the map limiters fumes I have an rpm/load table I values type 8047 which is the maximum value that I put on myself when I mod. those 8047 should be 80,47 mm3), right?
I theoretically speaking of air at the inlet to the maximum load should be around 1200mg from 1000 rpm up to 5000 with load at 100% the air should always be that then 80*0,85=68mg
I now have the theoretical 1200/68=17
then in the map from 1000 to 5000 rpm at 100% load with a value of 8047 should feel good
I'm thinking in this way, munro and I do not understand the mistake where I have directly written as I'm thinking
now the value of the maf I think is lower than this point because if it was so it still should not hunt a tear of smoke, with this afr
look at the axes on the 2d map show the steps air that start from 300 up to 1050...you have to do your calculations on those
munro forgive me but I that the axis did not see it, I could also do calculations on the values that you gave me and ok but I want to understand why do not I view them, also because if I were to make another map, and not I view them I'd still be with the hands bound, I should make a log and ok pero I would like to understand why do not see them.
I am attaching the screenshot now, or are cecato I or there is a problem.
the axis goes from 07b542 to 07b560...
reduce a little the zoom of the titanium and the slider that is above the screen in 2d...
oooh here is perfect! now l've seen! that would be the map maf or the target value that I read in diagnosis, right?
ok now it comes me spontaneous a curiosity!
by changing this curve, you do not get nothing if not a defect in the ecu regarding the air is insufficient because the centealina takes a certain value and the engine to not able to give it right?
this would have to change in the event dimodifiche more heavy also to ****llo engine.
ok anyway now I put it to work immediately!
here's the new map! the limiter fumes I think I've got it right! rail pressure and its limiter the torque limiter I think that I have understood well, the foot pedal throttle and I think it's ok.
Go munro judges!
then the driver wish you left too soon, with rpm and percentage corner of the pedal...so you have a car that any minimum pressure accelerator pedal you run from under the seats...not exactly the best to drive in a city for example...
begins to moddare from 1500 rpm and 50% of the pedal for the rest of this map is quite good..
lim pair you want to inject only 56mm3?tweak it a try not to overdo it has low rpm because of the clutch and the turbo but after the 2000 rpm and you can mettoerlo to the iq time doing it also to the team at the end of the rpm if you want...
lim fumes ok good you have figured out how to intervene
rail pressure also here a little too soon to change and with the increase in the fixed 5%...the high is nice but the bottom not so much...from the screen into a grid of titanium, use the key S "interpolation" you will open a window with the "rpm and loads" to edit....parts with a 3% you have low and a 5-6% towards the high....
lim press rail is done well, but you could increase more in the bottom and only a limiter...
you're just flush with the press rail 1400 and the broken bar in the map and 1450 in the limiter...then the other limiters that you have suggested me and frank because they still do not li moddi?
good morning,
well, I have done the final touches
the limiters I made munro to take a step at a time, otherwise I would impicciato,
however, now I've done those also, the limiters iq not knowing how to act I thought since they are the limiters set them all on 70mm3 I don't know if I was wrong.
pero according to me is not so much logical sense because I am in the map now I have values of iq maximum 80mm3 would not make more sense to take them at least 80 limiters?
the pressures in the turbo I lifted slightly.
if you can munro, could you tell me what is the address of the egr so since I'm I close it also from the ecu.
I tried putting the map in the ecu and I tried it pero it goes wrong.
I'll explain
a ****s performance seems to be less compared to the old map, and as if it just touches l throttle after 2000 rpm you lever under snaps!
to a wire of the accelerator by salirepiano the revs between 2500 and 3000 strattona.
at full throttle it seems that you plant it almost seems that paths with more and less throttle.
smoke now do not hunt, not even a tear and the clutch slips only of the fifth, but hey, that's not ago text why now is change.
Hello project....then....
to begin the address the map the egr is in 0796de...
do you know how to do it right?
then the pedal six-party moddare as I said, but I start with an important increase....
scale a bit the request from the pedal....so what counts, and the request that you make 100% not at 50% pedal....
the real problem however is the rail pressure....I already told you to use the S key titanium and dre linear increase from 3% to 5%
you have given almost all of the map, an increase of 3% fixed!
the problems on the behavior of the car all depend on them...
parts in the map rail by 2300 rpm and from 50% and change only the last 8 curves with the increase that I said to you...
then you skipped a limiter press the rail function dellatemp diesel, which is what you suggested frank...
ah..I add the fact that it goes a little less is normal....with your old map and the ecu threw fuel to dry even when it is not needed now with this, the ecu knows exactly where it is how much to give....but if you want a little more fuel without having to scale the position breakpoint map, time etc...by a little more of the injection times in the 3 maps that you also changed your trainer...do not overdo it though..a maximum of one 10% more, but not everywhere....use also here the key S to the titanium...
as soon as I can redo the changes munro, thanks!
but that speech that I told you before of the various limiters iq is the right one? and as I put them are ok?
l egr if I'm not mistaken I have to smooth the map as a whole on the high value, right?
the last observation, but because the map the pedal, it seems to me to be put to the contrary? that is, the engine revs for as long as you set the map to be original, it seems to me you read to the contrary, the max rpm in fact seems to be the minimum and vice versa
you go put the highest value on the whole map!
adjusted the map a pedal, and rail pressure to see if I get it now
the egr and limiter still not I made them for a matter of time as soon as I can do them.
but on titanium there is not a way to select a piece of the map to set a value and bring the entire selection to that value?
munro but for a thing that is a little more to the point would it not be better perhaps to start with the press rail from 1000 rpm increase from there with a 1% and get up to the max with un5-6%?
thanks also to frank!
I had no way to prove it so and the throttle is returned to progressive pear seems to have lost a little ****s performance, and as soon as she reaches 2700 rpm in the shot seems to have a small decrease.
make a log to see what injects...
ok as soon as I have the chance I do!
so a rail and pedal over the map are fine, what are you saying?
however, apart from joke I think that as I said is a slight increase that you can do everything according to how I'm thinking I'd keep under the 1500 bar of the press also because I think that more that pump them may not give or otherwise I'd stressarla too much and unnecessarily!
the limiter smoke until I have the original turbo let's say they are at the limit unless I care to make it smoke but it would be the same stress a little foolish for the mechanical and exhaust temperatures excessive! this is what I understand I think is right!
the map of pedal I still have to understand it well as I have not yet understood the map thing to be made, I think they are iq, but I'm not sure!
and I still have to learn to calculate the time injections!
the map of pedal I look at it as a "multiplier" I raise the limiter and then I manage everything with this map(from what I could see).
a multiplier of IQ you say? and with what criteria you make the calculations?
because to me the thing that has made me a bit strange is that on the ori all rpm increases, decrease the value in the map is a little confused me this.
well, I have finished everything to the map, egr closed and limiter press rail 07EDB8 moddato this limiter does not wanted to put him in the team I only increased I think that this will go well.
as soon as I can the lighthouse the log.
I'm sorry the project and I am confused I have seen the file of a 147 instead of your however, if you need the axes of the map advances, let me know...
I'm sorry the project and I am confused I have seen the file of a 147 instead of your however, if you need the axes of the map advances, let me know...
I'm sorry, munro, now I am a bit confused!!! you may rispiegarti a moment please?
that is the formula that you told me is right? the conversion factors? however, if you give me the address of the map in advance I try to understand, I the axes and see if we are alone I can understand it, thanks a lot.

I was referring to the fact that in the other post I didn't remember having given that address are advances...
to check if the address that I gave you was accurate, instead of opening your file I opened the file of a 147 all here address advances in your file is always the one that I gave you.. cwt axes of the map advances to find them just before the map egr...
munro I don't want to put in doubt querllo that you tell me, however, to address 07d2cc does not seem to me to be a map, then it seems strange to me that the axes are so far usually the ones that I saw till now are all attached to the map.
I also tried to put it on winols but that address does not give me any potential map
try to ask for help to someone else on the forum maybe I'm wrong..
munro forgive me if you are offended! it was not my intention to offend you or mancartidi respect I'm just trying to learn! I know that nothing is owed to you and you do if you want to do it, and for this we are very grateful indeed! I need to force some straight wisdom, of course, I'm not going anywhere I'm trying to understand this map advances as it is made to me seemed not that how it's done around here! I hope no grudge!
I was not offended and I have no grudge I'm just saying that may be I'm wrong..
in fact, reviewing a bit better, I realized that the address I gave you is not the one for advance payments, then I'm wrong
the advances are 2 maps 16x16 that are 07e374 and 07e572 the limiter soi is in 07e254
careful not to overdo it with the advance payments otherwise backgrounds all calculates for each degree of advance in the combustion chamber you have 10 bar in pressure.
Munro good evening!
I thank you in the meantime and I wanted to inform you that I have done a lot of testing, will update on the situation.
in the meantime, I am attaching the latest map I have uploaded so that it is very good I might dare to have a hint of more with the times.
then I noticed a few things since I managed to make the log,
first thing by modifying the lim rail 07EDB8 the car in the shot on the 3500 begins to sob, and from what I have seen the press rail is a swing, do I need to understand why and then I put back the golds and the car pulls well only that the press rail is stops in 1350 and I have to study it a moment thing.
then I noticed that putting l egr all at 12000 the value in the diagnosis of the maf target remains set at 1200mg and I think that is normal
the value of the maf bed reaches a max of 750/800mg (a little bit but the car has made her beautiful war)so I find myself injecting 55mg that corrispèonde with the values in the map so I could raise a little the values in the map lim fumes since I still smoke, not even the shadow, and maybe raise a little the turbo seen that charge to 1bar and lifting this should also have an increase to the maf and the consequent increase in iq.
the injection timing so as to log arriving in 1092, which should correspond to about 20 degrees now I have to calcolarmi l advance and see if they are out.
I'm going to be okay, according to you, munro?
However, I put well now l've deliberately around 62mg to see if the clutch is already devastated from the old map holds, and in fact already so try a little to slide out, however, now I have set a goal i.e. to achieve the performance without a tear smoke to me it would be already a good achievement already so we are very close! And I think it could go even more than how it was before, and always smoke-free!
I also noticed one thing about the 4000 rpm l iq tends to go down also from the map ori is set, so now I would like to try, instead, to do that hold at least constant so guadagnerei on reach I think but not sure if there might be damage in this way
