Info on behavior alfa 159 150 hp

[ducati83]

Hi all I downloaded the map of my 159 remapped with deleting the EGR and DPF before work at around 2000 rpm you could hear a increase of boost with the remap ? become a real blow to the couple, and the alleged defect of the series ? accentuated....according to you where to intervene to eliminate or to diminish this feature?how to I make it more linear?
thanks to all

[ugoboss]

if you want an opinion you have to post the file ori.

[leandro89]

[ducati83]

thanks, but I attach to the discussion of the file ori....
deleted attachment, the file ori, which is inserted into the database if there is not, and in the discussion is the link with the number of posts

[ducati83]

ok I.....
here is the file ori to this post
https://www.professionalchiptuning.net/showthread.php?59-alfa-159

no one has given us a look at?
I also noted that walking at 2500 in 5th gear the turbo pressure remains fixed at 1500mbar.....not ? a normal thing....

[michele30]

hello , for me ? a bit review.
you've raised the torque limiter 400 rpm I would say to start at least about 1500 or a little before 1250, and not gradually.
the maps pedal are ori
rail ori
and the turbo ? you want to review .
same thing on the injection times have you started too soon ..
riguardala.

[jolidj]

different maps are missing . with that sw did you touch ?? have you used driver or something like that??

[ducati83]

no no ? my work....it was made by a mechanic that I delete the DPF....and since I suffer always the usual problem....I wanted an opinion....
I have the titanium and if I could figure out the missing map, I would like to put my hands because they not ? just by trashing...

[alfajtd]

the mapping ? completely busted...
I would say that ? just by trashing...

[franco75]

Why? it does not begin to do it alone, start with the map the pedal and torque limiters

[michele30]

I hope that you have not had to shell out money for a map like that.. also luca stanca

[ducati83]

? what I would like to do....for? not letting me give the addresses of the maps....but maybe the data that allow me to recognize them by only....in such a way that once you understand how individurle I am sure that in the edit, then I could better...

from what I understand now I should start with torque limiters(?I have found one for now) and with the map pedal...but for the latter I would find out what we find inside,and then the values with which it works....

michele sure that I paid....according to you, why? I came to want to understand how to make a decent map....since the pseudo-mechanical and mappers, there are hundreds of them around...why? do not try to do better...

[michele30]

you are right, however, seen that you have titanium, loads the file ori, do you find the driver and modify the maps in the driver.
maps pedal , torque , fuel injection , turbo, and the rail say the basics then you can also go on alticipi. and etc.
but parts and those parts to about 1500 rpm, especially in the couple not to have problems with clutch

[ducati83]

Here we see what I have combined

[sportknight]

these have ir? problems of friction to the 3000 :D
personal experience

[ducati83]

maps pedal can go, increases light but okay
the detailed quantity of the gas introduced to let ori ? legr and saw that you have the controls closed is not working.
you tell me what are the maps that you have touched off the driver?
be careful, why? there are several smudges, " I look with the mouse "
limiters fumosit? you can leave them also in gold , the increases are not so excessive.
pair ok
elencami maps out the drivers, what are they for you?
the pressure diesel is not good rivedila
injection times also, parts from top

ok thank you for the regard and then you will know? say.....
I'm glad that at least the operating logic is correct....
I would not like to do other cappellate but according to me for the time of the injection well should I understand that values are expressed in that map....advice?

guys I have noticed that with the cold weather the problem that is described to be attenuated a bit, but I notice that the car seems much more restrained that you're walking on air with the tires on the pressure....according to you?

Guys, according to you, once you have found a good compromise in acceleration and low very low fumosit?, what's going to tap for a boost homogeneous even after the 3000giri?just a matter of the quantity of oil or even excessive pressure of the turbine can give a feeling that the engine walls?

[sergiot]

in my opinion, the variations in engine thrust are really a small thing, especially after 2500 3000 rpm
in the map pressure diesel fuel, the changes are irrelevant and not necessary
in the map of the diesel fuel, the changes are imperceptible
the limiters have been lifted, but their effect ? is almost zero, why? in other maps, you do not require to go close to these limits.
the air pressure can? good to go.

[ducati83]

but you mean in the map posted, or in general?
c'? one thing that I don't understand:how do I change the map pedal, turbo, rail pressure etc etc....I don't get a extend of what I require....but known only to me it lowers the initial push type from 2000 to 1500.....and then I change the boost at the top...what? if strong pushes from 2000 up to 3500 I feel that salt fluid....and if down the boost from 1500 to 3000 me begins to die...or better not ? vigorous to get to the red zone....
then I would like to understand if ? a limit of the change that contribution....or I have to settle why? from life all that you can't? have?!?!?

[sergiot]

I refer to the map posted on 22-11.
with those data, the car takes a p? thrust with the low-and middle-accelerator +4-5% and not more than 3000 rpm
take a bit of thrust at maximum throttle, but only from 2500 rpm and up, +12%
I think that the effect that you describe in the guide is done predominantly by the changes to the intake air rather than from the fuel.
with the air command of the turbo can be pushed in pi? at low speed? but then up we go behind with the fuel.
I do not understand the meaning of the changes to the rail pressure
the car ? without the dpf, egr off, little butterflies swirl turned off.

[jacktheripper2]

Given that I still can't download your map I'll give you an answer to a question that nobody has answered, what do you find in the maps as the values are what they are. Maps pedal= torque expressed in nm, these nm are then converted into quantity? the injected fuel from the map 'deal? fuel injected, this amount? fuel injected ? expressed in mm3. From here, ALL. Meanwhile, this torque request, or mm3 that are required are limited by: 1) limiting diesel out of the driver (for maps with turbo stock it only takes 2), 2) torque limiter (expressed in nm), 3) torque limiters by gear (but a lot of you should already? have them already? to 1000nm except in the back), 4) map (lambda limiter fumosit?). The latter ? expressed in values of lambda, and ? to be converted to values in the AFR (if you write on ****** lambda to AFR, you'll find the tables of conversion, the stoichiometric diesel ? 1=14,7 not to have any fumosit? you should be 16 or even more? so you can burn all the diesel fuel, of course with the turbo stock I would put in 1 or even less for?, better a little smoke than a turbo broken). In this map the break point we have rpm and mg/Hub air intake, attention for? here the values of the air intake are in mg and to calculate the AFR you will need to convert mm3 who inject mg by mm3x0,84. Example: to 4000 rpm injects 62mm3 and you have to 900mg/Hub, then make 62x0,84=52,1; 900/52,1=17,27 of AFR.
Now already? only by changing these maps, the machine can? go well without having to touch the other if not a little bit of pressure to the turbo so you can burn the pi? diesel that you request. Here you can give 100 points on the last 2 columns in the grid, and 50 points on the penultimate.
I have explained the first main concepts now it is up to you to try. Of course with a bit of rail pressure, a little early and a little bit more? of injection times can you? still get a nice improvement, but for now it starts from the basics without complicate your life. Also, as it says in a very user-prepared to this forum, and the rail ? well increase it only if necessary to shorten the time of injection to the high amount? iq..

[ducati83]

you guys are terrific.....I think that what I have been explaining in this post is more than a good map nice and made....I have no words....
now will try? to make a bearing in mind what you said.....I rest a single doubt:I found the limiters diesel out of the driver, no, but I understand for? how to change them, what? touch them only in the points in which I'm interested in or should we change it all?

Great, thank you for taking the time in this way.

[jacktheripper2]

Change only where you need it. You have 2 do you, what 'similar' to the torque limiter, which ? a limiter of the high pressure pump, you can do that in a team, to how much you want to limit (I'd on 90mm3), the other after the torque limiter instead change it only in the first point of each curve, starting from the second if you want to or from the third, the first ? for 1000 rpm and the second for 1500 rpm and then even if you leave ori goes well.


Great, thank you for taking the time in this way.

I think that, first of all, you have to start from the basics and understand how it works and the ecu, from there you can? start to change how and where you need it..:)

[ducati83]

I confirm that this ? one of the limiters for diesel?
6532

[msport (exil77grande)]

I confirm that this ? one of the limiters for diesel?
6532

you can confirm that.

[ducati83]

ok but for innnalzare the ****l diesel oil only at the points where ? shows the maximum quatitativo, or at all points?

[panterargento]

The second limiter is to take it to the team (as long as you want to limit e.g. 90mm3) says jacktheripper2, the first where you've attached the screen increase it to brighten in the peaks where the quantity ? maximum.

[ducati83]

as always too good

[ducati83]

guys after several tests I pulled down this map....
let's say that I would like to first understand if I have a logic....even if I would like to scalarmi for good bp of diesel in the various maps, to adapt them to 100mm3 as required by the limiter and redo for well injection times.
now the formula to calculate the time of injection ? (IQ*(K)/√Prail, where the constant K= (√Prail * Tinj)/ IQ????

For the time of injection uses linear interpolation. 100mm3 on cars with turbo golds are tantini..

[ducati83]

do not grab:ok change them with the interpolation....but on the basis of what and how much?I with the formulas I can ricavarmi the time of the injection starting from the old iq es 70 es 90....because actually 100 are many and you don't need to go that far with a stock engine.

[jacktheripper2]

With interpolation, you put the value to 60, and for 80mm3 to tot rail pressure and then put the mm3 that you want to find and it will find the time. An example: x1= 60 y1= 787us x2=80, y2=975 x3=90 y3=.... y3 sar? time equal to the time that you will have to 90mm3.

[ducati83]

no excuse then I correct the statement first: what is this interpolation?
I interpolation the use if I want to have the values are scaled based on the maximum value and the minimum....but functions that give me the value as you explained I have not seen or do not know how to use I ...
what you say to me are calculated with an excel sheet by exploiting the formula of injection timing that is on the forum....

[jacktheripper2]

With the formula which uses to have the same % of increase from the break point. Example: (root 1600x975)/ 80= 487,5.. Now to 100mm3 will be?: (100x487,5)/rad 1600= 1218,75... Now considering that 100mm3 are the same 80mm3x1,25 if you 975us x1,25 is always 1218,75.

[ducati83]

now....I understand...
anyway, if you must do a calculation in percentage to do before....you just need to increase in proportion to 1.24 for each increment of iq...if the calculations are not wrong...but I think of you....

I don't know why, but ? deleted my previous comment in which I put the link to use interpolation. However, if you write a linear interpolation to find the computers.

[asdone]

The only other thing to keep in mind ? that pressure rail are low, you can lengthen the time without consequences smoky why? you end up injected in the exhaust :P
Then multiply by 1.25 is fine but on my map I had to climb gradually for low pressures until you get to 1.25, say, 1000 bar, worth cloud of smoke in thrust at low revs :)

The times are to be calculated. If must be calculated for 90mm3 (example) of those must be, nor more nor less. The fumosit? to low you can? then very well to solve in other ways. Just gi? just put the lambda 1.1 for the low that you do not smoke.

[asdone]

No, why? even if the rail ? mappable not ? instant up or down, and not ? question of the lambda, but of injection time too long why? all diesel fuel is properly burned, if you finish the injection ++ 10 degrees after TDC, even if you have air smoke the same why? the combustion ends up in the drain!

[panterargento]

I jacktheripper2, me with a map and informed with the times ori, the low-if to lunge it makes me sbuffata, which I then corrected with the lambda.

[asdone]

In the end all that counts is the result :) I see it so, and that is on my I resolved by going up gradually with the times!

[ducati83]

I have noticed that by changing the injection timing at low...intended as a low-pressure...hence the low numbers of revolutions....I noticed that going from 1500 rpm to the crowds while walking for example...the motor takes more time to get to the idle speed....but without fumosit?...or better, I never had any of these problems....

[checchitotiralaleva]

I don't reisco to understand why? talk of changing the maps injectors.
To do this means to fool the ecu, you penser? of inettare a certain amount? when instead the real deal? of fuel injected per cycle sar? more. Virtually all of the maps of combustion are a function of the quantity? introduced ESTIMATED - by changing the opening times of all the maps that do not touch will work in the real points of operation that are not optimized!!!
There are all the possibilities? to increase the introduction (in steady-state and transient), maintaining the correlation between the times of opening - rail pressure - quantity? really injected.
Attention also to the fact that the same map in the injectors is also used to calculate the durations of the pilot and of the post (the range between 1-3mg/hub)...

[asdone]

If one wants to inject 90, and the map only goes up to 70 it must be obviously, we have to rescale the map. If rescaling the axes, and acts only on the new values that are not c'? the problem with the other maps that use the map times as very likely will never read the new values.

The problem of editing the file without the "trick" the ecu ? some have the shared axes (the cio? an axis ? declared in a certain point and ? valid for 2 or more? maps), and not always ? given to know what are the maps that use it, this is for me ? a big limit, even using the damos that are difficult to find for a HW/SW specific.
I highly favourable not to fool the ecu, but ? pi? it is easy to say than to do (well)

[ducati83]

I don't understand why? these problems: if I know that a map such as that of the injection times works in a certain way and modify it by changing the rail pressure, turbo pressure, and the mm3 injected..I don't see a problem there...but most of all I don't think I fooled nothing...I am instructing the control unit to manage other ****lli in the right way and not the case....and the result, of course, if it all ? done in the best of ways ? a good operation with increased performance.
correct me if I'm wrong.

[asdone]

The way "right" would be to rescale the axes so? the ecu is aware of the new values to manage.
According to this line of thought, if the map time is up to 60 mm3 and you want to 70 you have to delete a column and add in the fund with a value of 70 with the values of opening of the injectors increased ONLY on the new column.

[checchitotiralaleva]

Ah ok, understood so well? I agree. Do you intend to complete the map injectors extending the field of use of values of flow rates over the last break point by extrapolating the opening times for the new break points, following the trend of the values calbrati for the break points earlier.

I didn't think ye were come forth out even by the range of break points... the maps injectors that we build the tour come to ****lli introduction top 15-20mm3/hub compared to the maximum adjustment that is used during the resolution engine. (adjustment mother - of- pi? high the other ratings that you will find on the vehicle). For construction I mean the measurement...

Eh ? clear! Understood! Hello to all

[ducati83]

kids often in some of the maps edc16 fiat group, I changed these two more maps after the torque limiter....a by the value 8192 I suppose it is diesel and the other? why? lie?

[panterargento]

Those to me and made the "Time" when I defappato...honestly I don't know what they are :confused:

[jacktheripper2]

kids often in some of the maps edc16 fiat group, I changed these two more maps after the torque limiter....a by the value 8192 I suppose it is diesel and the other? why? lie?

A lifting time of a little more? of 100 points, which is roughly from the original ? 10000 fixed ? a limiter diesel fuel based on engine speed. And certainly not for the luca stanca. The one in 8192 that you say not seeing the screen I don't know what you say, but not ? refers to the diesel. 8192=100% of pedal or "perfect functioning of the system" for other maps.
The only map 'diesel' in that area with 8192 on a break point ? a limiter diesel fuel according to the operation of the system shortly after but the time from what I remember do not touch.

[ducati83]

I understand, but then you move to do? or better, when should they be touched? why? both the ones that you say that the one right before with a value of 8192, in addition to be increased to 10000 and the other a little more? like you said, they are also stretched out, like ever?

[jacktheripper2]

I understand, but then you move to do? or better, when should they be touched? why? both the ones that you say that the one right before with a value of 8192, in addition to be increased to 10000 and the other a little more? like you said, they are also stretched out, like ever?

As soon as we could? see a screen say? my for well as with 8192 now I do not have in mind what you mean. Maybe e-mail the address that you say. The one with the value to 10000 fixed should be extended only for injecting 100mm3 up to 5000 and beyond but not for another.

[ducati83]

1cbd90 and the other 1cbdf6 all and the two immediately after the torque limiter;the first ? 8192 then as said before, the value 100 in decimal,the other ? to 10000 but is the portara at just over 10200....

[jacktheripper2]

1cbd90 and the other 1cbdf6 all and the two immediately after the torque limiter;the first ? 8192 then as said before, the value 100 in decimal,the other ? to 10000 but is the portara at just over 10200....

The first ? a limiter in recovery for? does not have values to 8192 as you say. The second ? what I have already? said the cio? a limiter diesel.

[ducati83]

in fact, doing the accounts....would limit the rpm...or the pedal...in fact it is brought to 8192, which would be 100...but can you explain to me how you get this value?8192 ? in hexadecimal...

[ducati83]

Guys I made a small map....what do you think?I'm trying to give a greater thrust in the low and try not to let it smoke.....for now, I feel only small tremors in 5 and 6 gear recovering from the 1500giri......then I lowered some of the maps pedal...leaving gold and aligning the limiters of the gears....
also I try to eliminareil vacuum up to 2000 rpm, and the thrust from at that point....you ? attenuated but still ? noticeable....

[jacktheripper2]

I still can't download the attachments, but if you give too low rpm only risk of frying the clutch and flywheel. If gi? as it was with the shooting at 1500 rpm vibrated a bit on the fly ? better if that area let it completely original, especially the limiters for diesel given that if there are a lot of times the map pedal asks for a lot more? at low revs.

[asdone]

You have ... raised rail, advances or turbo in the range of 1500 rpm? This, in parit? diesel fuel, pu? give this kind of problems (tested it on my poor 147 jtd)

[yannsaba]

The problem ? always the same ? impossible to work in that area and then have problems with the stock clutch, especially if you already? chilometrata, and also if in case issues do not c'? they were in the immediate you can be sure that sooner or later jump out.

[ducati83]

I raised also in that range of rpm....in fact, I'm trying various things to try and understand where you can? intervene to prevent malfunction....then even more: if I give increments to map the pedal under 30% of the pedal....shifting gears even with normal gaits...I hear the noise of the engagement gear, release the clutch after the change....I know that ? the problem why? with the map ori does not....it always depends on the quality? of the clutch?

[yannsaba]

If you play with the turbo and a little diesel can't do much in that range of rpm. The discourse ? even if you work up in that area, however, you are in the part where the turbo starts to push (For a talk on the physical component), then, if the transmission unit has the weakness we do very little. The noise that you hear depends to 90% from the flywheel ? the sbattachiamento of the gears that you feel the gear change. For curiosity? but how many km has the car???

[yannsaba]

Ah then according to m? if you work under that percentage of the maps pedal you jerking not to laugh...

[ducati83]

it is, in fact, I've noticed that at low rpm the third the fourth the car at the time seghetta if slightly under load.....
anyway, the car has just 100k...made with great care and with the clutch ? new...about 20000km...and I drive very very quiet...let's say that mechanically ? all-in-rule...I removed two times the rate for work of improvement...no processing...change the oil every 20000km use specific additives...in short, mechanical problems, he has not...why? the original I don't even feel the engagement of the gears and ? one of the few alpha to not scratch the back and the first even with frigid temperatures...

In my opinion, especially with a turbo as big as my playing of advances in the area of low-iq, low speed the car ? reborn completely. Especially at low rpm normally c'? a little advance for a question related to the production of Nox chr grows with the increase of the advance

[ducati83]

ok so I advice you to tap the advances in the area 1250-1750 rpm from 5 to 20 mm3? but most of all they have of the average parameters to which you refer?the cio? I try, with so many degrees of advance up to a maximum of 10 for example...or give degrees growing?
I wanted to try giving 1-2 degrees.

[nasone147]

tried to close a p? the vgt?8%!

[ducati83]

close and then increase....and always in the low rpm then 1250-2000?

[jacktheripper2]

close and then increase....and always in the low rpm then 1250-2000?

Closing the vgt for sure that you have a better answer for? c'? the risk of creating too much an overboost then. The advance payments should be calculated on the basis of the end of injection original, I have made a excel sheet and I decide how much to inject after tdc. Sure to give you 10 degrees more ? a folly?. Remember that increasing the advance raises the pressure in the chamber. At low revs will also inject after tdc serves to decrease the lag why? the turbo charging better. The maximum yield is obtained when the piston has the maximum charge, do we? the injection must end 13 degrees ATDC (after top dead centre) for? you have to keep in mind of the ignition delay, the more increase of the rpm and the more this increases. In the file, if I remember c'? also a map that tells more or less how much ? to the various laps. At high rpm come up to 10 degrees of delay in the combustion, that's why? must have? try to finish the injection the more close as possible to the pms.
Change the advances in the pu? bring great benefits, both in terms of consumption and yield. For? it is necessary to consider many factors and small mistakes can do damage in the long run. Test with 2 degrees, a maximum of something more, but don't go much beyond that. Also the management of the pre-injections ? linked to this (especially as it changes the ignition delay), as well as the afr set to change the speed? of combustion.
Before the mod the advances I light some document related to the combustion.

ok there I was working on the spreadsheet of microsoft excel for calculation...? I stopped at the question parameters to be set in the map or, better, I wanted to streamline a bit the formula in the sheet by the calculations in the main part.
so if I understand correctly: close the vgt and then increase....for? I have noticed that sometimes touching the parameter of the...at higher rpm, I lowered the pressure....now I don't know if other factors could be causing the problem...
for the discussion advances, I would like to first make a edit with 2-3 degrees to understand the car's behavior as it changes...then I'm interested in pi? elastic at the bottom...are not in search of absolute performance....even why? the clutch does not hold....then avoid the expense of 600€ ? the first thing I think of....

In the meantime, I don't know com'? the excel spreadsheet uses, so I can't judge. I created the my I open the map time, map rail, and the map advance. From there, I created the sheet, watching as inject after/before tdc for different rpm and injection. To the low you have 5/6 degrees Atdc about on the 16v.
Considers that it must also keep in mind that with the egr closed, the combustion will be? fast and the area where we have all those degrees Atdc ? the area where the original egr ? in full function. At high rpm you get to inject at tdc at 4000 rpm, 2 degrees before or a little more to 4250 rpm and about 5 degrees before to 4500. This just because? at high rpm, the ignition delay increases. I recommend to stay the nearest as possible to the tdc at high revs (with high iq of course be at tdc sar? impossible, but there is talk of over 100mm3 of fuel injection). In my opinion to low to keep 5 degrees Atdc or more? ? do you go into boost before the turbo.
If you want to by 2 or 3 degrees, but not more. And the more you get closer to 3000 rpm and the less I have to give. From 3000 rpm and up, lift it with little iq, indeed, from the 3500 you could also lower it with very little iq in order to have less engine brake in the release.
This is what I say to you ? tried everything on my skin.
Ps: with the most advance you'll probably get the engine from a p? more noisy to the increase of pressure in the chamber, for? you will be able to do the climbs while standing at 1200 rpm wire gas without any problem (and then it depends on what rpm you start to mod the advance).
Now I hope that I have said stupid things, and if I said I'd like someone to correct me.

on my paper I'm doing on the basis of this formula
<?END of INJECTION (degrees) = (TIME INJECTION) / (1 / (Rpm / 60)) * 360 - ADVANCE(with the data in the map /2)

now one thing that I don't understand:you obviously parts from the assumption that the data in the map are in the clear?
now, I am of the values at the bottom of which are among 1,88 e 3.50 degrees DPMS, then you can get into recovery I get closer to TDC, and then give 1.5 degrees would improve the thing....

Cos'? the last /2 that you do in the formula and after that remove the advance original? The formula ? right, but that last /2 is not we want. I like the formula to use:
Tinj?rpm?0,000006= .... Deg - Deg advance ori= degrees of end of injection after the tdc.
Taking values at random, suppose that we have 975us at 2000 rpm, and with 4 degrees of advance, all at full load. Then the formula will be: 975x0,000006x2000=11.7 - 4= 7.7. With these data, then the injection would be 7.7 degrees after tdc.

And why? split the result? You must not divide it here, where was the error. For the rest of my formula and yours give the same result if you end up not split.

[ducati83]

cos? I had the past and explained the formula....then it seemed strange that from the map ori, on the bottom I duration of injection is only 1.88 in?

[asdone]

Mhhhh... maybe you have said "divided by 2" why? they considered a cycle instead? a ride? But the degrees are degrees... the "/2" there it goes!

[ducati83]

ok anyway I'm still pi? with the change advances.
also tonight I tried the car and I have to say that with 2 degrees between 1200 and 2000 rpm the car ? very very smooth and shoots well....then I gave it a couple of degrees to the vgt and the turbine has lost the effect of the lag...at least in part, time will work? better to file the details...but I think I'm on the right track.
thank you all anyway

[ducati83]

So guys, I developed this map and the last change I made this morning and I have to be honest the car goes really well....salt, smooth and rapid, up to 2000 rpm and after it lengthens very well,I don't have the wrench due to the torque, to arrive quickly to the limiter and the infinity 200 in nothing....zero smoke at least during the day not ? appreciable...and the turbine never work to the maximum. on the contrary, often have to 140-150 sixth to a max of 1.2 bar....I am very satisfied, for? reminds me of the erore calibration control unit: remember that if the nm required in excess of 450 gave the error but I have not overcome, you give me a hand to understand what value I have given out maximum scale?

thanks

to me this error, and gave a little trouble at the cecksum,I had to save without driver and then let it calculate the programmer

[ducati83]

hmmm, to tell the truth I have not tried to write before the ori, and then again this....and then how should I do to not to calculate the chk to titanium?

[jacktheripper2]

The map conversion nm/iq ? the original? This error can? give for that. If you can turn up The breakpoint also alzali everywhere, and even those of the maps during the regeneration, then leaving the map ori.
Also check that you have not touched a bit around.

[ducati83]

the bp will get them up anywhere, even in the maps that are indicated by you.....the thing that I don't know ? the map conversion nm/iq-why? I don't think I have ever found....someone asked me to, it might indicate?at least the area and what to look for...
thanks

[panterargento]

"Deal? fuel injected"...the three-axis: rpm, nm (mm3) injected

[ducati83]

ok thank you...but how to handle such a map based on other changes in order not to have the error?

[jacktheripper2]

The map you can leave the original up to 100mm3 that with the turbo golds are already? too many.

[ducati83]

it is, in fact, I did arias trials, and now resumed? the ori....let's see why? for now, the problem persists...also reporting other maps ori....I know that the imputed ? just that...
