View The Full Version : Opinion the map alfa romeo GT 1.9 JTDM
I ask for an opinion on this map, and the first that I do, definitely missing a lot of stuff, I wanted to know if it's good approach or if I'm doing it all wrong, also I wanted to know if I have properly closed the swirl, and if the diagnosis I see DPF not present
I enclose ORI and MOD
thanks to all
Hello,
Hello,
there are still many maps, however, with regard to the maps, the pedal should be good to start.
torque limiter is too low, if you make a comparison between maps pedal and rev limiter you will notice that the pedal request X nm of torque, but the limiter does not let you do it...
Map prex rail does not make sense to touch it, if not, increments the time of injection, most of the prex rail means more energy required to operate the pump, a rail, an effort that is not giving any advantage.
Working on the prex turbo without overdoing it with the increases in the limiters turbo you can take them safely to 2600 for the moment, keep in mind that the same turbine mounts the 147 ducati corse 170cv that has limiters 2700.
finally someone answers me, good maps pedal we are almost ok, limiter, torque increase, if you do not wish to increase the prex turbo, but work only in the timing inj and advances you can do??
ok, I've stretched the timing inj I think in a way congruent to where I increased the prex rail, turbo still I have not altered by choice, what do you think? I also increased the torque limiter
instead, for the DPF and the swirl what do I say??
Hello,
the DPF seems to be ok, but to the eye can sometimes miss a few points. what did you use to exclude it? did you already? physically removed from the car?
OK for the block of the swirl open.
OK lim torque
tinj can go if you want to work with the methodology of the maps wrong, prex rail still we are not there, consider also that the increments of tinj are not such as to having to take on the prex of the rail, in each case toccherei only the last 3 columns and spins a little more? high, the rest for now let ori.
The prex turbo for now, leave it gold if you're not touching it, however, if you want to otterene real gains you'll certainly have to work on that with the increase of the injected fuel you have to compensate with just the right amount of air that you can't give if not with a greater pressure of the turbine.
Another council to continue with the work:
If you look at the map quantity? fuel injected, you will see that BP are already? scaled up to 100 mm3/inj then on this map ? necessary to intervene, in any case, I advise you to analyze the BP of 400 nm seen from the map the pedal require around 420 nm, you'll notice that are required 100mm3/inj.
A good thing would be to climb the BP of the map times to do in order to get to the 100mm3/inj instead of the current 80 (+5% increments that you have given).

I used Once more some of the directions found here and there, the Dpf is already removed from the car by about 20K KM and I have no regenerations, but I diagnosed the car with a DPF, which let's say for the purpose of important not of interest but to get the job done ad hoc and I have to fix, and just wondering this, however, truly many thanks for the advice that you're giving me, you're one of the only ones who are doing it.....thanks again now the lighthouse some of the fixes and poster? a new map.
then I corrected the limiter rail, I have increased a little in the Tinj, as far as the fact of climbing the BP of the map times to do in order to get to the 100mm3 instead of the current 80 (+7% increase, which I have given), and still perhaps too difficult for me, however now some of the fixes I made.
ok, I can confirm that Time the job runs correctly and your car should not even give the display problem of the clogging to 1000%.
With regards to the presence of the dpf c'? a control bit so that it will be the car not equipped with the dpf, as soon as I have a moment I try and tell you where it is.
for Tinj ? pi? simple how many do you think.. here's the formula to calculate Tinj100 = Tinj80 + (Tinj80 -Ting60)
Said cos? without further explanation someone could argue about the accuracy of this formula, or on the fact that the result is really Tinj100, really? to have a Tinj100 real ? well pi? complicated why? you should consider many other factors, among which the opening time of the injectors to the different prex rail, however, with the formula you will have a tolerance of about 2 to 3 mm3 which ? pi? that acceptable for our purpose (to have the time to 102mm3 or 98mm3 instead of 100 is very good).
Not ? can, however, purely theoretical (for us mere mortals) to calculate the perfect time to have 100mm3, fiat tests with instrumentation suitable to verify these values.
The dear good Tidus1985 in a previous discussion here on the forum has dealt extensively with the topic calculation of the Tinj with interesting calculations of the opening times of the injectors, if you are interested in the topic also for the purpose of information from a look why? definitely worth a read.
Back to your map prex rail is fine for the moment, incrementerei still slightly limiter rail depending on the Temp and fuel but ? just a small suggestion ;-)
Map tinj 8 and 10 mm3 leave them gold, that amount? practically use it with the engine at idle, would only pi? incrementandoli without having advantages.
I'd work at least for now, only on tinj 30 40 60 80 calcolandoli for example, to get 35 50 70 100

thanks again truly for the availability and for the patience, and then summarizing the tinj 100 would be a tinj 80 + (tinj 80 - tinj60) from the ori, -so if I understand correctly, the tinj 70 would tinj 60 (tinj 60 - tinj40) and to calculate them staggered is used, I believe on a "proportion" at this point, since we don't have the tinj for 70 or ****th e good-natured it may be fine as I thought to myself??
I figured we are all here to learn and share there? that we know ;-)
? the spirit of this forum !!!
Tinj70 = Tinj80 - [(Tinj80-tinj60)/2]
Tinj50 = Tinj60 - [(Tinj60-tinj40)/2]
Tinj35 = Tinj30 + [(Tinj40-Tinj30)/2]

well now we can understand something of it, then the times should be obtained from the other times inj, of course, simplifying (at least I understand it better) TINJ70= TINJ80 - TINJ20/2 that would be TINJ10
on the contrary I'm sorry, but if instead we make a calculation in%, i.e. the TINJ70 than TINJ60 and 17% longer can also be calculated in this way??
for example, in this way we should be with the given estimated 100 70 50 35, you always attach the test
somebody helps me?
no one helps me?
then I made some adjustments lowered the torque limiter as resonant with the flywheel, give me an opinion I attach the mod to the ori can be found at the beginning and in the database, more than I have corrected the DTC that time damn I had deleted
this is another update to try some opinion
this is another update to try some opinion
the speech ? usually, you have to modify the injection times are so important, then ? useless to seek the perfection on the pedal and torque limiter!

to change over to the map time by following the advice of paul to the axis of the map refers to the flow of gas, in such a way as to make it clear to the ecu when the diesel you get is actually going to open for a certain length of time the injectors.
But then I am not limited to iq 80 cause limiters in the map? Then I still have to readjust the map ahead of time with the new Bp?

find the limiters and adapt them, and the same you do with the advance, to get info about search on the discussion of the 147 of tidus, there are all the limiters.
In practice, so I'm going to not fool the ecu right?
In practice, so I'm going to not fool the ecu right?
yes, perfect!
place the most recent rev BP still not updated, I am looking for a expert opinion to assess any long-term damage
thanks to all of you
then place the base (at least I think) with all LIM IQ unlocked to inform the ecu, map full stock all the limiter brought to 90 SQ.MM check the accuracy, of course, EGR off, SWIRL off, DPF off with more time to switch off.
the surge in diesel are all there, but you have to figure out where to edit them, no ? the maximum pave all... looks like they are made from the original, as they are set up the axes, and considers that decrementarli not c'? reason... the other thing, the turbo must be touched to give him all this diesel in pi?, and also the pedal will be? should be put in hand. Consider that the injection times the original when max 80mm^3/s, so if you want to go beyond will be redone. Necessary to change the torque limiter, otherwise everything else remains the series...
Then the dafep, leave him with-bit only, you can't? see the crap that creates the time...
Some of it was just to know if the base and lim iq were righteous, and all now we have to study the above and mappo see what happens
place the first map-informed those who have an opinion??
there are errors after the second limiter, diesel, definitely made with the mouse, check the differences, the limiter of diesel as a function of the temp of the water I don't like how you did it, for you it's well already from the original one because in the optimal conditions, limits 110mm3, have adequate maps turbo personally, but still uses the last value for the values of mm3 additional then it may be fine, and the timing of fuel injection if you riscali you have to give a correct value, so are increased in proportion growing on, according to me is not good mind you limitavi to deceive the map, down payments, I would do it by calculating the pms to find the advance the best, even only a degree in that definitely not the fara bad, the turbo I don't know how you have changed ? strange, rail you have not touched ok to be a pleasure to me, to maps time you load a sheet done by me, which tells you how to calcolarmi for injectors 150hp with the factor of "charge download condenstatori/time of opening of the needle" to add ? a calculator on sheet exel
The times I calculated by t inj 90 = t inj 80+ (tinj 80 - tinj 60 /2), the map turbo you intend to rescale the last bp of 90 mm3 of fuel? Thanks for everything

in fact, it is the limiter, I made a mistake of a mouse thanks to have noticed it, the other 2 limiter in fact, reviewing with winols could stay stock, thanks again I make the corrections and post the new mod again thanks for everything
then, look at the file exel, every step of the process pressure to a fixed number to be added to the injection time real ? the time it takes the electronics of the transistor and condenstaori and the mechanics and then the needle to do the job, if it were only for the electronics would always be the same, but if you know how to work an injector you know that he in the moment of the opening has the same pressure in the chamber above the needle and on the one below, when requesting to open the solenoid aprela vent valve of the upper chamber of the cylinder tigliendo the pressure, so the pressure on the lower chamber of the needle push it to the top and this opens the injector, by this evinci more ? high pressure faster will be the time of mechanical opening.
meanwhile, I thank you for the Excel sheet I am trying to get him to calculate the timing inj but the accounts do not come back I see discrepancies also 100 us, according to me it is necessary to know the time of opening pins for mine, which perhaps differ somewhere, in the meantime, now I try to get them to calculate it and see what comes out, because by changing the values of 10 mm3 up to 20 are exact perfect 20 begins to unpack a lot
I calculated from the maps times a 1.9 jtdm150cv E4 with a dpf of a 159 2009
instead, it switches back perfectly, take your map, 1300 bar 80mm3 we 1089 us ok?
subtract the value of the time of opening the needle of my table on the 1300 bar ? of 297us, then 1089-297=792, this ? the actual time of injection for 80mm3, let us divide it by 8 to find 10mm3, 792/8=99us, now there risommiamo the time of opening the needle of my table on the 1300 bar ? of 297us ( same as before of course) and is 396 us, we see the map and look at some of you the value ? 395
You are not sure? we do another test, 1600 bar-80mm3 ---> 968us, sottraimao our fixed value in my sheet exel to 1600 bar ? 275 ? there is 968-275= 693, now we want to find that I know 15mm3? we 693/8= 86.6 us time for 10mm3,now we divide this value x10, and then multiply x15 then (86.6/10)x15=129.9 us and we riaggiungiamo the value previously removed the cio? the fixed value in my sheet exel to 1600 bar ? 275 hence 129.9+275=404.9 us, we see on the map and ? 400us, I would say that 4us margin there can be no?
place a correction following the advice of the good tidus that thank you very much, I just have to make some correction on the advance should go...those who have a look?
the limiter of diesel fuel as a function of the temp of the water I don't like the way you did, for you goes well already from the original one because in the optimal conditions limits 110mm3,
sorry tidus if you speak of the limiter to the address 1cf426 is not a function of the TH2O but as a function of Temp Diesel if I'm not mistaken..
that was slightly retouched because I saw it on the winols that the limitation began already at 80 C temperature Diesel then I preferred to turn it up
the seosnroe should be before raile of the high pressure pump, in short, before the diesel reaches 100? without being heated actively we want !
The sensor is in the sandwich of the fuel filter you say that there comes a score 80 degrees??
be 80? there are many, if we must get sicurzamente comes to us in non-standard conditions, perhaps in the summer to 40? under the sun with the engine idling
You say?? The temperature on the rail, and very high, however, if you can get your hands on....but that temperature and that of the limiter in the object or diesel fuel coming from the tank? ?
Instead, the limiter just the first one that the damos called water pump balance what would it be? ?
that meant this:
limitaion quantity due to quantity balance of the high pressure pump"
the address of the damos and this: 1CF496
in the alpha seems to me to be moved a few bits but, however, and the one just before the limiter as a function temperature diesel
