View The Full Version : Opinion the map tractor New Holland T7070
What about this mod? Let's say that I would like to take 20/30 HP from 225(251, with boost) original.
The increases in pi? or less I have them deducted by comparing a file of T7040 (182 HP and 215 with boost) with that of the T7070 ori.
You know that curves are those 1F53AE and 1F53E2?
Thanks.

you can make pleasure to receive a mod already available to us, instead, has given hassle that you have violated our rules here, as we have always helped and not made the file because otherwise, you only get the meal ready, and I don't see what you learn if you do not copy.
Sorry, but I had asked for an opinion on a mod that I did and so I didn't think it bothers you it of violating the regulation. I don't seem to have requested a gi file? done...
in your mod you have only increased the press rail....
a map very beta anyway.....
I do not think in that way reach the desired result, but a little more feel, above all,**** s "recovery rpm under load".....

by sending the file in a pm to a user that nonb has privileges to download from the forum, according to you, you have not violated the rules?
You say that I looked at the differences between the maps of the T7040 ori and the T7070 ori, and then a little to the driver of the ecm... and I had not noticed the map of the rail is important for maximum power at 1F190A.
Even why? I was convinced that was not working to 1600 bar from the original.
Increasing the map of the rail for? should I also increase the bit 1F2732 right?
and adjust the limiter 1F277A
The other thing, increasing pressures and injection times the consumption indicated by the on-board computer rispecchier? the reality?? According to me no... why? the ecu believed to inject tot mg instead there should be more?.
But if I modify the map conversion between torque and mg diesel fuel, for example, if to 1000 Nm at 2000 rpm I need 70 mg of diesel fuel, if I put this value to 75 mg the ecu inietter? 75 mg of diesel if I have a request of 1000 Nm?
By doing so? the on-board computer data are reliable?

I apologize for this, I didn't think that could be a problem as it was a file golds and a file modified by me to come widely incomplete.

touching press rail times and map conversion, according to me, the data reported on the trip board will not be attendibilissimi 100% why? go to vary the algorithm of calculation of the latter, which, however, communicates with the ecu.....
for? I don't think is a big problem....
for the press rail seems obvious that if moddi the press in addition to its value in gold you have to adjust both the biti single limitation that the map of limitation....

I was told by a friend who had used a tractor "laboratory" we say of those that use it to evaluate on the the field issues, and he was about 30CV in pi? of those of the series but still in the on-board computer was also a higher consumption of the one that consumes my series. Then the house as a modification to the powers keeping the signs of consumption related to the actual use of fuel? Or ? a fact that derives from the map conversion?
I do not believe that the data on consumption is resumed on the map conversion....because this has a functionality? of all internal, all sw ecu that it serves this to know on the basis of the nm, which should deliver much fuel you need to inject through the press rail and the times....so I think that the data on real consumption is taken up by the trip board on the injection time....
for? I believe that even with the car fully ori values of consumption data do not reflect fully the reality but, rather, an estimate of the average consumption, not actual....
The map to the 1C6552 that the ecm is giving me a function of rpm and load ? right? Watching with winols, I think it's a function of the rail pressure and quantity? fuel injected?
Aren't I?
1C6552 ? the map that ecm called the "injection, split map1/1" honestly, I did not understand what it is......
a strange thing that I noticed scrolling through all the files in 2d ? that are not able to find the DW......
then Fede78 could you kindly explain to me the mod from 1D39F2 to 1D314??what is this all about??
ah...I couldn't even understand what they are 1F53AE and 1F53E2....

1C6552 are injection times but not as a function of rpm and load as indicated by the ecm, but in function of the rail pressure and mm3 of fuel injected.
1D39F2 then starts to 1D3994 watching it in 3d with winols seems to be a limiter
1d314 is missing a number... did you mean the map that starts 1D390A ? This should be the torque limiter main
1F53AE and 1F53E2 I don't know what they are...
and for the DW or map the pedal....you tell me??
May be 1D48C4? Or 1C3628?
but you don't have a hex file or a a2l to check???
Connfrontando maps ori T6080, T7040 and T7070 I noticed that I have 3 bits of the same value are increased, are 1D863A, 1D894A and 1F7182
In T6080 values are 9590 (the tractor has 181CV of maximum power and 690 Nm of torque)
In T7040 values are 10510 (the tractor has 224CV of maximum power and 938 Nm of maximum torque)
In the T7070 values are 12000 (the tractor has 251CV of maximum power and 1025 Nm of maximum torque)
All these tractors have the same hw and same sw that's why? I can compare them.
According to you are the limiters single bit?
Wanting to make a mod without touching the injection times and the pressures of the rail you should still get good results, no?
But how to proceed?
Increasing the amount? fuel injected f(rpm, Trq) 1D82E6?
(doing so? in theory, when the map pedal to me, requires a certain torque, then the ecu according to the torque request, I inietter? tot diesel, if I increase this amount of diesel, then the avr? also pi? power and torque? Am I right?)
Clearly then there are the limiters to adapt...
A limiter that limits to 70 mm3 of diesel, what 1C5CB2? lim diesel f(temp diesel)?
Pu? be a right way to begin with?

I would like to read the map of the 7060...the ecu ? a common bosch edc 16c39... how did you read it?
I have the magpro 4.2, I can do something via serial?
Thanks a lot!!!
I used a gallo2 using the protocol of the t6080 that conveniently close to? ? the same ecu, same hw and sw.
Then I made a cable from the OBD diagnostic socket of the tractor that you find in the seat behind and to the right.
These are the connector pins of the tractor
Pin = GND
Pin B = 12V
Pin E= K-line

do you know if there is also something for the diagnosis?
The diagnosis is made with the official tool, the DPA5 combined with the SW New Holland Service Tool. The hardware for? coast enough so unless you are a dealer or specialist workshop ? fatigue...
I don't know if you'll be able to do something with the Cummins Inline... that wanting is also from china... it's Just that I don't know if with the diagnosis you see something.
In the issue ? that is missing the SW... maybe even a common ELM 327 may read as we do on the cars.
Also Texa doing something but the prices are high for an end-user.

Oh yes, I understand...thank you for the info...
Someone with the mag pro 4.2 ? managed to make the reading of the ecu?
Just select from the list a common drive that has the edc16C39 and read the obd, the cio? from the k-line?
I had tried with Mpps and gallo 1260 using the protocols of the car, but nothing...

Pu? be a right way to begin with?
hello fede78...your idea of moddare only for the map conversion nm>iq according to me ? from discard....as this map ? the reference that the ecu uses to "choose" the BP in the map Tinj,mainly,but in a lot of other maps, e.g. that of the press rail,etc.....the problem ? that if you do not match all the other maps are related to each other, the ecu does not do you give? never the iq that you ask for...what? we put you in the map nm>iq in the BP where maybe you 500nm and 60mm3 of diesel fuel, you go to moddare the iq from 60 to 70...if you do not match all of the bp of the other maps where c'? that iq of 60 before and 70mm3 after the ecu rilever? the error in the calculation algorithm.....
The problem then ? then you have to change all the other maps related to this?
What I thought was that the sequence was more? or less this.
1. Map pedal that requires me x number of pair
2. Map conversion torque/diesel from the x value of the pair before I turn into quantity? y of fuel to be injected
for? I'm at the point to inject more? diesel we need to increase the time or the pressure of the rail....
Or are there other avenues?

Or are there other avenues?
there are many other correlations between the maps...the ecu before moving from point 1 to 2 to a minimum other 3-4 maps of limitation and correction upon which it bases its calculations...
for what it's? I.. from the request in the map, the dw goes to the maps of limitation as the tl, which in turn are controlled by the sl after the ecu established the value of nm "filtered" by all of these maps goes to the map nm>iq
from here, then the micro knows that tot the request of nm correspond tot mm3 of diesel and on maps where one of the axes c'? an iq in mm3 go to "choose" the bp is more suitable in the maps and times and press rail adapted to that "transitional" that serves to give you the iq of the final..
this, we say that ? the method in which I believe that the ecu works...
if you go directly to increase the time and the press rail all the algorithms of the consultation and control of the above maps do not have a way of esister functionally, because in the maps "faucet you mentioned earlier, you will say what and how much, and how "time" inject....then almost immediately jumps in the maps "faucet" injectors...what? the map times...
Talking with a friend, whom I had asked to increase the diesel fuel injected I had to force things increase the times of injection, this is when I said that ? said why? maybe with these times of fuel injection in the map pu? be able to inject up to 80 mm3, for example.
In several I have said that in any case, this map does not provide the pi? of 70 mm3.
This pu? be determined by the limiter to 1C5CB2 ? ? a limiter diesel as a function of the temperature of the diesel?
Other bar/, which may limit to 70 mm3 which can be?
And above all, you can't see or calculate from the map ori how many mm3 can be injected, leaving the original times?
If someone are interested in the data... the engine ? 6-cylinder, 6728 cm3, the series delivers 225 hp that pass to 251 in the mode? boost, the maximum torque ? 950 Nm to 1400 rpm, which goes to 1025 Nm at 1500 rpm in the mode? boost.
in the forum,if you are looking for, c'? a formula that will let you know,knowing the press rail and the times,of which the amount of fuel you inject...I use the conditional because as well you said there are many maps of limitation...the only way to know in which the bp of the map times the micro goes to read once h? "refined" the request from dw, and through the log....
Tomorrow I see if the mechanic I can do a log with the official tool...
Today since I had the tractor in the workshop for some updates, I went to do a little diagnosis on my own. Unfortunately for? in the log I recorded only some of the data... While in real time, I saw many other, and more? important... mg/stk, torque, turbo pressure, air mass, intake....
Maybe I set the wrong data from the log... however, I decided that I take? the interface... to having different means and then can I use it to update the various software...
For what concerns the log I have the fuel pressure in psi and not in the bar.... and as the maximum value I 16317 psi, which correspond to 1125 bar.... so that the ecu works in psi? the curves of the rail arrive at 17000 psi?
With regard to mg of diesel, unfortunately, in the log are not written but visually on the monitor, I've read more than 120 mg/stk.... can?
As soon as I have the tool to do? tests ir? detailed and you have the logs of the data that interest me.
120 mg of diesel fuel can "be there" benissimamente....
ultimately we are talking about a 6700 cc....
the only strange thing are the units of measure in press the rail and iq...normally the edc16c working in a bar for the press rail and in mm3 for the iq...
For the iq pu? be that I am confused and I have read mg instead of mm3. For the pressure this value instead of the I in the log.
the maximum value in the test I had to 1828 rpm, timing advance injection 12.40?, pressure environment 14.53 psi, pressure fuel 16317 psi, pressure goal 16144 psi
Since this engine in the version "marina" pi? extreme comes to 560 HP... possible, therefore, that this having virtually 310 less ? like that it is nerfed, and then could return to the fact of the rail 1125 bar?
I'd like to see the map of the "marine"... clearly will also change many components, but in order to do these powers takes too much fuel... and I think that it is necessary to work to the limit with the pressures of the rail.
However, there are other settings of the marine engine less thrusts type 450 hp and even less maybe...
Not ? that someone who has the Map3d 2007 "cloud" for the case take a look if you are in the database of downloadable files for free?
if ? for this reason, the americans from their cummins mounted on the various pick-up dodge, etc..they take out even more than a thousand hp from these engines....just that you take a tour on youtube and see real monsters with double pumps, common rail,double or triple turbines, and the more it has, the more, the better...for the maps...if you chew a p? English and if you want to sign up on a forum with a very full about on these engines will recommend the "competition diesel forum"....
Ah ok thanks for the tip! Even double common rail pumps! I'm going to take a look...
However, as soon as I have the tool, I make a diagnosis made as it should be to understand what the rail pressure works on my tractor.
Here I am after a bit of time, but with work I am always busy! Then with regard to the mm3 injected were also indicated in the nameplate of the motor: Fuel rate * the advertised power 127.0 mm3/stoke
For the rest from the diagnosis, I see that the rail pressure ? in the psi, and a maximum value I have about 16000 psi which is equivalent to 1100 bar...
To raise the amount? fuel injected so I'm supposed to find the map of the driver's wish, which currently sar? about 127 mm3.... or if there are limiters that limit to 127 mm3 ?

I don't know if the cock of the law! not in the list!
Here I am back here after a bit of time... if I wanted to increase the flow of fuel without lengthen the time of injection the only way ? to raise the pressure in the rail?
I ask why? by comparing the file ori of different power, I have the same times but with a different pressure of the rail
even if you raise the rail pressure, the ecu map and the time it will choose a bp with a pressure lower to give you the same diesel that you are limited by other maps...
But if you increase the flow rate, for example, from 130 to 135 mg and adjusting the various limiters in the ecu knows that he has to inject a quantity? greater than diesel right.
Assuming you want to leave unchanged the map of time (1C6552)? as a function of IQ and the rail pressure if to inject the new deal? of diesel the original times don't last enough I should then increase the pressure of the rail right?
What then?
From the diagnosis, I see that these values of the rail pressure are in PSI and not bar and turning up in the bar I get that I have the rail pressure of about 1100 bar... that I seem to be few... But other tractors of this series with less power have pressure even more? low and times are the same
I don't understand what you mean...you now you are limited to 70mm3 of diesel....
your map times and has been calculated from the mom bosch 1700 bar of rail and 90mm3 if I'm not mistaken...
if you do not adapt your limiters and maps rail does not inject the above...
if you increase only the press of the rail and its limiters adjusting all other limiters the ecu won't be never to choose the bp 1600 bar and 800us for example, to give you 70mm3 but it will choose the break point of 1100 bar and 980us....
and anyway 130-135mg in reality are 152-158mm3 of diesel....if now with 70mm3 you 225cv with 158mm3 you shall have as a minimum the double...
remember that we are talking about a edc16c39 precisely where the c stands for common rail, and in these ecu the iq should be read senmpre in mm3, even if the diagnosis or the scanner give us the iq in mg....
The map of the limitation of IQ as a function of the rpm 1D428C has a conversion factor of 0.02 and, therefore, should be limited to 123 mg.
The map of time 1C6552 ? climbing up to 180 mm3 (factor of 0.02) and 1700 bar.
This hex and a2l...
The fact remains that the pressure of the rail from the diagnosis to me to be in psi and turning it into bars correspond to about 1100 bar
make a p? as much as you can....
For? having two ****lli power cio? 225cv, and mode? boost (transport above 18 km/h, with the pto under load) 251cv I have to have two maps, no?
Since the map of the times ? gi? climbing to the IQ up to 180 mm3 and up to 1700 bar I don't think the servant to change it because if you increase the various limiters of IQ and the torque limiter when the avr? a request for a diesel that is higher than the current ecu I andr? to choose the time of injection based on the new IQ and the pressure of the rail right?
Torque limiters that are the limit in the error conditions of the engine I can also do not touch, right? The Cio? if it goes into recovery for some reason ? pi? right that is on the values that are set by the manufacturer?
I tried to make two maps, and I have written, the first about 10 days ago, the second a couple of days ago but I have not yet had the opportunity to test it in full.
I would have a few questions:
1. The rail pressure 1F205A, pi? the trend... what? I have that 1400/1500/1600 rpm the pressure ? pi? low schemes lower, then higher revs then the pressure increases. Looking at the map of another tractor pi? recently (with urea but the same engine Iveco NEF N67 ENT), as well as having the pressure to 1600 bar has a trend of linear pressure increase with rpm and iq
2. The curves 1D0B6E, 1D0BC0, 1D0C12, 1D0C64 I did not touch because from what I understand from damos are torque limiters in various cases of motor error. I have done well? In the mode? of the correct functioning should not be affected. While 1D390A Torque speed curves ? the torque limiter that I modified.
3. Map Lambda 1D665C I don't know if I've changed ... well.
I attach the file cos? if someone wants to give a look and an opinion.
Thanks.

I'm attaching the screenshot of the map of the rail of the T7070 and T7.270
In particular, in the first, the pressure has a trend at the met? the diagram I have the pressures pi? with low iq that increases going to the right..
Then the pressure according to me are very low, I looked at the parts catalog, and both tractors mountain the same injectors and the same pump to the rail.
What do you think?

The series t7 does not have the recirculation of the exhaust gases within as a instead of c'? the 7000 series..
we talk about the percentage of recirculation in the order of 20%.. I think this affects the amount? diesel iniettaro..
the series t7 returns have typical efficiencies of motors without recycling.. would be interesting to see some technical iveco if ? possible to mount the camshaft of the t7 on the t7000.. maybe faith knows something?
thanks!

Yes, I have said that one has changed the shaft to the cams... The problem more? what else ? that to mount it you have to disassemble and****to turn the engine. Exactly, I don't know but it must be why? if you do not****turn the engine then drop to the auction?
With regard to the development of pressures? not ? that eventually changes the diesel injected, where in the t7070 I pressures pi? low avr? however, injection times greater equality? of fuel to be injected.
And if you increase the pressure without changing the quantity? diesel fuel is injected into the avr? just the time of injection pi? short but I don't know if the map ? cos? because of the egr..
The Cio? to say if I look at the curve of 130 mg/cyc I have these pressures in these rpm
700 rpm --- 950 bar
800 rpm --- 950 bar
900 rpm --- 950 bar
1000 rpm --- 950 bar
1100 rpm --- 933 bar
1200 rpm --- 923 bar
1300 rpm --- 921 bar
1400 rpm --- 899 bar
1500 rpm --- 857 bar
1600 rpm --- 978 bar
1700 rpm --- 1082 bar
1800 rpm --- 1161 bar
1900 rpm --- 1212 bar
2000 rpm --- 1233 bar
2100 rpm --- 1203 bar
2200 rpm --- 1141 bar
The maximum torque the engine has at 1500 rpm (when the pressure ? pi? low) and the maximum power seems to me to be right at 2000 rpm (where I have the maximum pressure)... ? a case or c'? some reason?

Yes, I confirm that ? a lot of work to change a camshaft on these engines.
for? the benefit would be significant according to my point of view..
Faith, you know for certain that the operation transmission shaft on the t7000 with the new t7 ? come to a good end?
That cost has the tree?
With regard to the injection pressure vs. engine speed at a fixed flow rate of fuel, I read the how to adjust the duration of the injection..
This? since 1500g/m, we have the pressure pi? low we will have the duration of injection pi? high; 2000g/m where we have the pressure pi? high we will have the duration of injection pi? low..
Then you can? also read how to atomization of the jet: 700g/m, we have the atomized jet pi? finely that to 1500g/m..
She informed me on the price, from what I know the operation ? been done with success on a Case Puma.
For the speech pressures back a few posts you said that having the egr then iniettavano diesel less having less efficiency of the engine, at least cos? I have understood.
For? if it were so? the diesel fuel would be limited in the map lim diesel as a function of engine speed. Instead, in the T7070 (tier 3 EGR), and T7.270 (tier 4A with urea and without EGR) quantity? maximum diesel we at 1500 rpm.
T7 has higher values, but ? also true that has more? pair and pi? power.
But I do not understand the fact of the pressures pi? low.
As you can see each evolution of the common rail system you have improvements, but we also have pressures pi? high. Many say that the pressure is not important... but, I think that benefits.

Perhaps I misread the table.. when you say the map of 130mg/cycle, means to inject 130 mg each burst right?
So I started with this parameter fixed, and I deduced, since the pressure ? note, that the variable ? the duration of the injection..
I made those arguments on the timing of the injections..
Back to my reasoning or have I missed some step? :)
about nef with egr vs no egr the difference between a diesel engine and the other as ? as a percentage?
Thanksss!
Is the reasoning ? correct, what I say that even if in the nef with the egr had put the same map of the rail of the one without the egr and not changing the quantity? diesel fuel is injected we will have the engine with the egr injects the same quantity? from the original, but if we have more pressure to make? in a shorter time.
So ok that may inject less fuel, but if the same fuel inject the less time that problem?
With respect to the shaft cams have told me that is 5/600 euro and in any case the difference is felt especially at low but since the madness to mount it and forget it.
To see the differences of diesel I should check with the T7.250 perhaps that should have the same power T7070, there guarder?!

Higher pressure means better atomization and more time of injection pu? to improve the mixing of the charge to burn the cio? it mixes better with the fuel with the air?
Thanks for the info cams..
last question about the hard work done on the Case Puma: the customer is good, has done a lot of work? do you know if ? the state made an adjustment on the mapping?
The fact of the tree I don't know... I was told by a friend who in turn had discussed on a forum of this and I don't know if then had been made in the mapping.
Clearly ? an intervention that benefits and definitely can? more help if the tractor is mapped.
