as you act on a map in the case of the intercooler?

[magi1984]

I have a curiosity? to ask, on a bmw 120d edc17 gi? mapped and sfappata and with the egr closed, the customer would like to change the intercooler, and put an oversized one.
I have to intervene on the map, or not ? need being gi? been mapped with an increase of the turbo pressure of about 150-200 points???

[legendaryslave]

see the evolution of pressure before and after the diagnosis, and will adjust accordingly, according to the theory, there is a decrease due to the increased surface area of the radiant mass to cross, but an increase of oxygen due to low temperatures

[SandroMarciano]

as a rule, an intercooler cools down the temperature of the incoming air more, so it increases the density? in parit? pressure. If you do not increase the diesel, we say that the replacement of the intercooler to serve? little.

[magi1984]

there are many ways to increase the diesel fuel, injection timing, amount? fuel injected, rail, etc, etc, there will be? have fun

of course, if you have any tips are welcome

[SandroMarciano]

Depends on how you performed the change, or, if you simply increased the stroke, without adjusting the axis of q.the. then you will need to make increasing the time until the attainment of the smoke, and then go back (to trial), but if you have unlocked the torque limiters and q.the. then will we need? set the lambda to a value greater than 1100punti if you do not want to smoke and increase the torque. If the limiters were properly adjusted with this system decides everything the ecu, then just a single attempt....

moddando times it bites better...and if you put a ic plus I bet that the guy wants to senire feather...

[munro]

in practice, an ic plus good workmanship can cool down more, the compressed air that passes through it, even with the same operating pressures turbine for a speech efficiencies...
and as I have said this to cost reductions of temperatures makes it the most "thick" the air intended for the engine and then with more oxygen...
generally then you can give more diesel because c'? more air and more pressure turbo because c'? more disposal of heat of the same, that does not affect in a significant way, not even the operating temperatures of the engine...
if you want to make an ad hoc work according to me you should be saying to the efficiency of the new ic, and through this calcolarti theoretically, the quantity of air at the exit of the ic in order to compensate, so stechoimetrico with diesel....
otherwise you risk going to trial and error before getting the right "mix" of air and diesel....

[magi1984]

the intercooler ? the kit performance BMW
so theoretically I would only need to find a map of the kit performance BMW and studiarmela

[giuseppe1374]

I'm at the point if he wants to put the intercooler would also recommend the replacement of the injectors

[bart]

According to me, lowering the temperature of the air fed into the combustion chamber, you might consider to work on the advances of the injection and/or the pilot injection... ;)

[magi1984]

advances are already? been modified, as soon as the client loads the map, I say if ? satisfied or if there are problems! Thanks to all for now

[msport (exil77grande)]

the map that give the bmw just 20cv so needless to study it.
basic how many hp does your machine have?
besides the egr off,luca stanca,the map and the charge-air cooler has other changes?
you are loading for the first time the complete file, or was it already changed?
you might incur a nasty surprise.

[magi1984]

the machine has 177cv, the history ? this, he had a map, soft and dpf active.
nothing to say on the map, really well done, you see that ? a map made with winols and not with the ecm, where ? been recalibrated the demand of diesel fuel in an appropriate way.
the owner ? went by the same preparer of the first map to disable the fap and the nofap ? been done with the time.
the time to delete all of the DTC, and when the owner, if any ? realized required the preparer of the original file in case of need.
this has not wanted to give it to her and she has lost the customer.

came to me, I read the map with the nofap of the time, which is fixed in a suitable manner nofap, and increased the horses, and then I rebuilt the original file starting from the mapped bed.
the machine ? perfect and happy customer.

now the owner has mounted the IC of the bmw plus, and I made a third step, as soon as I have news on how to be the car will update

[marco]

in my experience if you do not put a turbine plus do not need farzi problems aflusso air and give more fuel and I made a few days ago and I put the intercooler but the turbine and golds.make a normal map and you'll see that it will go well. however, msport says to be careful of the mod. these maps you may have the burden of the problems.

[magi1984]

the map ? been made and tested, the car ? a bomb is very strong and does not smoke for nothing. The customer ? pi? that satisfied them, and now I porter? well as a 320d e46 to do, in short, ? all went ? well.

Son intervened both the timing and injections but not in the extreme way as you can? to think,that on the torque limiter,the first for? I was also appropriate on the foot pedal and the amount? injected

[cicciogsr]

eye to the chains of distribution... some have a rib that devaste the chain...

[marco]

excuse the magi 1984 but then intercooler lai put with this map?

[magi1984]

sorry in Italian? :D I don't understand if you're asking me what intercooler I put it or if I changed the map after mounting the ic

[marco]

haha excuse you I was wondering if you had also put intercooler bigger.

[msport (exil77grande)]

haha excuse you I was wondering if you had also put intercooler bigger.

the discussion was open just because it has a mounted intercooler and wanted to understand how to intervene in the mapping after this mechanical change.

[angelolsp]

map pilot injection?? is more vulgar map the pedal?

[SandroMarciano]

No, it has nothing to do...

[angelolsp]

and what is then? you may spiegarmela I've never heard of

[SandroMarciano]

watched a bit of the theory of operation of a mjet. There are simple changes to make...

[angelolsp]

has far as I understand, the pilot injection raises the temperature and the pressure inside of the cylinder to the combustion
