Map Alfa 147 1.9 JTDm 120 hp

Hello all, I am a new user and I wanted to post you the map of my 147 1.9 jtdm 8v 120 hp, made first by a trainer, then retouched by me to be a little more powerful.
The machine has fairbox ramair and downpipe so that's why you will find on the map the change of an overboost decreasing, because with an overboost original I had peaks of 1.8 bar with precta and the original filter had not, after about 15 maps, or found the right compromise between speed of rise of pressure and peak and constant working on prex turbo and an overboost, here are the maps.
I have not worked on the maps limiters diesel very much, I preferred to work on the maps injection time, advances max 2? and rail pressure for a 5% at the most.

I agree to both comments and criticisms, so long as they are constructive and not of the type "this map I don't like" and it disappears

the pedal does not ? adequate to all the rest, and it's good, 1c1fac know what ?? I don't know nemmno I because even the damos says what ?, the egr goes well torque limiter too soon, too many steps, and not adequate to the demands pedal the fact that it tends to come up is fine, advances the absurd should beat the engine are destructive of all those degrees, 1d1fdc and to follow must never ever touch, the turbine 200 points, but you're a little high blood pressure, you should know what you go to meet, verbost I don't know really because I never touched, and when I did it I did it in this way, the rail from the top where it is not necessary? this is only my personal opinion which may well be contradicted by anyone someone much more experienced than me definitely will give you some other indication

Thanks a lot for your assistance, to improve the map, I ask you according to the tuanesperienza, aumenteresti or diminuiresti lanmappa pedal in this case? According to you, the advances are too high 2 degrees maximum? SSinceramente I thought no, turbo be nn I pass the 1.55 bar pressure gauge with this map, thanks for your advice oreziosi

but the pedal alzalo more and you can start with loads lower than for cash advances, do not give up so down, but you do something like the rail by a 5% - to-medium loads and high loads is not needed you can go down to a 4% to pressure the turbo if you have monitored and it's okay if affixed you have adapted to the changes

thank you but they are young user I can open the attachments :D

here is the review, following your advice,

the I tried it and not me ? liked it, seems to be braking, and then I have to roll up their sleeves and I have rebuilt a healthy plant from the first project, remodeling max of 2? at full load at full rpm down rpm and dicarico up to 1? of advance, increased torque limiters in the area above 2000 rpm and increased maps pedal, and given a 10 to surge of fumes, which if I'm not mistaken should be limiters of diesel fuel based on the air being blown in.

I hope I have improved, and in the morning, I try

I had a look at the "mod v3", keep in mind that I have the ecu on the car of my father, and now of the tests I've done enough... advances not c'? nothing wrong to change them in a substantial way, the limit we say are 27? maximum at 4500rpm, to stay safe, then not ? said that with 27, the car is handsome, but... the values that change, thinking that they are bit of the rail are not one of them... until 17000bar should not disconnect because the bits are to that value...
1c1f86 let ori, does not affect the behavior of the machine... then if it does not touch the various limiters, but you focus on the maps of the time, you don't need n? touching the torque limiter n? the pedal...

Then how ? now it's not okay because I touched both times that limitatiru torque and map the pedal? Should I adjust from one side or from the other?

then I made a log with fes, 3000 rpm at full load I am 83 mm3 of fuel, 1675 bar and 1.55 bar of turbo pressure, I had set out to test the 1700's bar, but you can see me limited, here is the step 4 that I've tried fes, it's good as a diesel 160cv or I still need, I should also measure the mass of air? correction to the injection on the edf I should check on all 4 cylinders?

sandro want to say that touching only the injection time we don't need any of the pedal end of the torque limiter?

from the mod v3 of the mod v4 I have noticed a marked improvement in the shooting and of the wickedness of the uto increase of less than 1 degree, the advances from the meta load and 1500 rpm and up, but quite a lot, and it makes a lot of smoke now, only I don't know quantyificare 83mm3 of diesel fuel, how much power can provide you with the correct stoichiometric ratio

then, by doing a few tests that further increase of 2% and tinj eportando the rail to 1700 bar (or found the 4-bit limiter rail that were in fact set to 16000 ) I managed to bring the rail measured in 1690 against a request in 1974, from fes, the strange thing ? that the amount of fuel injected from the edf ? always 83.37mm3, then I wonder if by changing the time he read correctly the quantity injected or the colcoli not according to time but according to the limiters, the quantity of air for these measurements at 3000 rmp ? of 1235, with turbocharger at 2555 absolute value, the ratio of the injection air can go? does a bit of black smoke only at full load, otherwise nothing, I have no precat only cat, nodpf, where I could act to ask for more torque and more power, I seem to meet a wall at this point, the value read from the edf for the diesel fuel in mm3 ? correct, or do you offset? this is the map of the last test.

I apologize for the wonder, but I seem really expert at the game, as you can see, I don't expect answers dry, but I do have evidence, and I try to give me answers to what I can even looking for but at a certain point I find the walls like this now

then I made 2 accounts and as the afr does not go down ever are 17/18, so afr I should be at 3000 rpm, with 66.2 mg of diesel fuel equal to 83mm3 and 1265mg air the report ? still 19, so I'm extending the usual 14, but comnque a bit of smoke at full load I can see it, so it should go well ammeno that as I said before, edf is not false reading of the mm3 of fuel because of the change of the map tinj as a function of the bar and mm3, so I could do a porporzione of the reading of the edf of 83 mm3 and bring it to 115% of the opening is set approximately as the value at 3000 rpm, since the increases range from 11% up to 17% at 1800 bar, and then I would like quanita injected 83mm3:100%=x:115% that does 95 mm3, equal to 76.3 mg, and then with a afr of 16.5 that anyway ? above the threshold of smoke; hence, and then good, all this in the belief that nothing limits the edit time inj I set up.

correct me if I'm wrong :D

I think I have solved for the required power, while varying the time nn I felt a greater power, but increase the time abinato to an increase of the same consistency on the request torque map call from ecm titanium " quantity of diesel fuel injected" gave me all the pair in more than I wanted to, so brutal that I had to give it 2 percentage points in the less time and fuel, with a maximum of 87mm3 of diesel chr now also marked by the edf, and the machine really strong no smoke

place the v10 defined ? a map nice boost but due to the rail pressure of only 1700 bar and then just a 6% more, turbine that is not super the 1.55 bar and torque limiters with lower values below 2000 rpm, I'm not supposed to spoil anything, given the performance I think I will be around 155/160 bhp, are the feelings of driving of course, someone can give us a look and give any tips they are always welcome?

the map does not ? evil, I don't like how you have changed the turbo pressure and a question comes to me spontaneous, don't smoke in the car with all those increases in the injection time?
for the rest I think I have read here and in the forum that the geometry variable that you changed the cos? because of the mechanical changes, etc etc

then, the map turbo I changed the way of the downpipe without precat, and airbo ramair as piccava to 1.8 bar, then ? was necessary to rebuild the an overboost with a pressure maximum of over 3000 laps of the 1.55/1.6 that states to the downpipe that throws away the gas boiling in the turbine li holds a quiet, more no, then nothing from the peak pressure stops at 1.45 for slire progressively up to 1.55 bar, and still not smoke for nothing, in the mapping step, I have calculated that by injecting 89mm3 of diesel fuel, equivalent to 75 mg of oil with a mass of air sucked in 1265 grams, I try to keep the relationship techiometrico above 14, in fact, are about 17, certain load to full load, a little smoke, but more or less as stock, maybe a hair more but still little, if you see the right to maintain a good time of injection I have increased the advance of about 2.5 ? at max load, thank you very much for your comment

I have not followed the latest versions, however I see to answer as much as my Sunday allows me...

*joseph: yes, I mean that if one chooses the way of the change of the times ? well continue with that, so do not care of the rest, even why? there are many other limiters that do block the q.the. acting through the torque limiter and the pedal.

*tidus: I'll note that the "q".the. 83mm^3 ? distorted, doesn't it ? real, how did you mod the time, try to put only the original times, from the edf measure is always a q.the. 83mm^3, but the machine will go? much less.
Another thing: my turbine to those values ? disintegrated after 10000km... do you...
then I did not understand what you mean when you say that you have the request of the rail you go to 1940bar, how ? can? also the bits that limit the pressure as I have already? written are 1700bar, and not at 1600, if you try to overcome 1700bar you'll see that the machine will be damaged and off... (I advise you then to keep in the car with the diagnosis to clear the error)

but the car has a dpf?

no, not even the cat

vabb?,however, it seems to me anyway, over-all that diesel..but that clutch has? possible that it is not yet crumbled into dust?

excuse the wrong ascribed to the request was to 1640! the turbine at 1.5 bar, the ec, I have about 10000km before ? was also a 1.6 with a peak of 1.8 some time when I had to touch up the map for the problem of the downpipe, then I was broken, as also the elettrovalvolvola who commanded the depressor and, also, I got the piccata of 2 bar, and still thank god no problems with the turbo, even whistles, apart from the noise in the suction dell airbox obvious, what would you give as the maximum range of you? according to you, with those times as injection? the fact is that as soon as I touched the map"q of fuel injected " without cambiare3 the times that I had already set up I abuto in net gain than before, a sign that the map ? anyway, a limiter diesel in my opinion

no, of course not! and even precat, catalyst and exhaust

to be honest, the thing that the clutch hand to hold, no upsets me too much, I was just informing on the spare reinforced for the future, when I stumbled in the codes of the parts that are the same for: 120 hp 150 hp 170cv, so it should hold up at least for now,to absurd to even slide, 159 of a friend of mine with 170 bhp remapped already sled, my, that must be almost as much as the her as the edge of the sled, for nothing, not even the vibrations, of course, nn lunge never sottocoppia, I try not to break it! :D

The clutch 170 2.0 that mounts the 159 and Giulietta ? different. The 170 you are referring to yourself perhaps ? the that of the 170 Ducati corse?

Exactly, I mean of 1.9 147

I looked now, v.10, you have an i.q. effective approximately 95mm^3...
this diesel fuel does not slip the clutch, and I am much more?, and if the clutch does not have a lot of time does not create problems, the only risk to me ? represented by the turbine... mine don't ? was cos? lucky... at 170000 km, of which only 10000 with the pressure you use to has abandoned me... I wish that mine is an isolated case (although I don't think this data needs to be pumped with 1.5 bar)

According to you, how can I spingetmi ancors with the diesel?

the engine holds also safely 120mm^3, but the turbine is not going to make? sending you all the air you need. we say that the limit ? represented by the smoke, and ovviamte up to the stoichiometric one. Obvious ? that is not to talk about reliability

Well I mean a quantity that is manageable with but 1300 mm3 of air ? quellonche I can get with turbine 1.5 and reliability as the most increase in the shortest time should I anticipate I suppose, cqlcolare the amount I can use about the relationship of my current injection time, knowing that as you say they are about 95mm3

gi? 90mm3 for that machine are sufficient if we are talking about changing the stock, otherwise, if you want to go beyond you have to at least replace the injectors, and intercooler, and the turbine, the turbo then down for if not that turbine will last from christmas to st. stephen,using a maximum pressure of 1.4, then I wanted to ask travis how much diesel fuel does inject his car and the injectors as they are combined-why? an injector has its calibration and I don't think that can? tolerate the 120mm3, but this ? my opinion I don't want to offend the work of no one.

I agree, unfortunately for? the only way to increase the injectors of the 147 mjet 120cv (as far as I know) ? put the nozzles of the injectors of the 159 2.4 mjet, at a cost, however, prohibitive. I have a jtd, I have worked with mjet, but the things more? extreme I've done on mine, and I know that I need to mount the injectors, and upgraded (I thought of those of the 147 in fact), however for now around with 1500bar, but I turned also to the pressures pi? high and times *1400bar in the order of 1300us, not ? nice as a change, I know), but the machine works with those injectors yet!

I knew that the 1749v up to 1.5 bar holds, and 1.6 bar for the 1749mv of 150 hp, I is 1.3/1.4 already in stock

oh, I forgot, having downpipe the heated less, I'm sure that holds 1.5 bar, so, for the less still I don't even have the game on the post, I have mapped to 70000km I 85000 and no problem, turbine, which, for some period piccava to 1.7 bar for problems to the valve-pierburg

See for yourself...

I'm sorry, I don't ? still allowed to open attachments, if you can direct me to the image I would be grateful

I'm sorry, I had not made the case, search on ****** "compressor map gt1749v" and among the images you will find the chart that shows the efficiency of this turbine to vary the boost pressure and air flow rate.

seen, unfortunately I can not read the meaning of the diagram because I don't know what it's worth, the supply ducts of the 147 you may tradurmelo in words more simplified? :D

not ? cos? simple... the flow is not ? a simple air flow, but ? a small, dimensionless parameter that depends on the diameter of the duct, the temperature of the air, and if I remember correctly density. The one you've shown ? the curve of operation of the compressor, to know how to work you'd need to intersecarci also the curve of operation of the turbine.
The problem though ? the curve pi? to the left you find ? a "surge line", and to the left of this c'? the area of pumping, that is the one you should absolutely avoid. The area of pumping ? the pi? dangerous for the turbo, why? in those areas, we check that the boundary layer occupies the whole of the duct, creating a cap, so the pressure tends asymptotically to the maximum value, but the impeller increases the number of turns anyway...

In the graph relative to the 1749v, you can see that 1.5 bar "gage pressure" are practically next to the surge line...

Ok thanks, in the meantime, I made a correction to the map, 1.4 bar maximum but after 2800 rpm salt xomuqnue almost 1.5
