Limiter pressure Turbo Alfa 159 2.4 jtdm

[Nightwing]

Hi guys, looking at the map of my 159, the limiter pressure turbo ? set to 2500 (ke correspond to 1500 pressure), the pikko max turbo pressure reaches 2420 between 3750 and 4000 rpm.
I was wondering, if I pikko max 2500 and adapt all the values in proportion, riskio to have errors in the ecu saw ke would be equal to the limiter?
In the case of qnto can I increase the limiter pressure turbo?
Thanks.

[jolidj]

if you bring the pressure up to 1.5, you need to increase the rev limiter. if the ports equal to the value of the limiter definitely will give error.

[Nightwing]

thanks jolidj, kme I suspected, but how much I can push myself to increase the limiter turbo?

[marco]

then the limiter prssione turbo phallus as the turbo pressure, but according to you, how to mod. in points, or impercentuale this you need to know.

[Nightwing]

actually at the moment I don't know the slightest difference between points or percentages, and which solution is better between the 2, since if ragionandoci above the percentage change should be the + indicated in order to take under control the parameters without overdoing it too much.
in other discussions I read of percentages in the order of 7% to be pi? quiet, any damage, if I consider this as my limiter turbo 2500 I could move to 2675 or am I wrong?

[marco]

sorry, but with that pro. are you using ecm 2001-titanium on the map is the high value and let's see how many bars are there?

[marco]

I'm sorry, I forgot nightwing mod. the map pressure turbo, and put it so we'll work on it.

[Nightwing]

ok marco, tonight as soon as I get home, work on the limiter and pressure on the turbo with the increases of 7% and place the mod file.
thanks x support

[jolidj]

I don't know if you can download or not , but if you see on the forum there are explanations of how to increase the limiters above 1.5.try and read that if it says.

[Nightwing]

unfortunately, I know the privileges x see the file or x download:(

[Nightwing]

I'm sorry, I forgot nightwing mod. the map pressure turbo, and put it so we'll work on it.

finally the mod. with the changes on the group turbo2489
but the control variable geometry you changed or left unchanged?

[Nightwing]

I know that if I put anke the ori can do well poko:p

[marco]

then I saw your map so it's not okay you conziglio to see on the forum if there are similar posts, and study them. because you have given the 7% and then over the whole map. but he is thinking when the engine alminimo in that rpm is if the car is alminimo the turbine serves.?

[munro]

the fact that has raised the pressure of the 7% even at idle doesn't mean anything.... not ? said to have that pressure just because? to touched the map in that area....it would be too good cos?....the engine designers could benissimamente to do, to invent turbine vgt or twin turbo sequential to not have lag..if it was enough to "write" in a map with a given pressure...

I increased that way to get qlkosa in pi? already from low revs, the engine idling, running at 750 rpm and I changed the values from 1250 rpm perk? I thought ke would increase the quickness? response of the turbine, since the ke at the moment, I feel a little empty down x and then have a boost around 2000 rpm.

axxarola seemed too good to be true:(
but to increase a p? pi? the responsiveness anke at low revs, can you? to qlkosa (changing anke other parameters), or ? a mere illusion?

[James]

hi Nightwing, the turbo tries to modify it in points absolute and not as a percentage, according to me, the work is better.

[franco75]

if you want to increase the responsiveness of the turbo you have to give diesel, one should never consider a single map, but the whole system of control, timing Advance, Fuel, command, VGt, turbo pressure, torque required etc...

[franco75]

I give you an example, from the file posted I took the one that should be the map of a pedal, I have highlighted the request of torque at 1500 and 2000 rpm.

As you can see, c'? a hole, almost a chasm. Perhaps the designers have created to not clog the fap

you advance that, according to me, I would only repeat to me that I am an amateur and I have very little experience, the map turbo is of little use because it is used almost always, the map control VGT mode? not reatroazionata, which is adjusted by the vgt on the basis of the mm of diesel fuel and rpm fottendosene pressure.
According to me you should leave for now the turbo as well as, if you want to more increases in the diesel fuel, and you'll see that go up? also the turbo and you'll have the opposite problem: namely, to try to lower the pressure.
Try to get the map turbo 0.3 Bar (300 points) and you'll see that nothing changes

yesterday evening I looked at the map VGT, I noticed ke values are pressok? idendici at the same rpm kn changes in the last 2-3 tables, start high and then decrease with the increase of the number of turns.

ps:
To increase the diesel, I have to increase the rail pressure, right?

The values are those appropriate to maintain the desired pressure by the manufacturer. It is clear that at low rpm and low loads you have to have the geometry completely closed to try to get an answer faster, then gradually opened to decrease the pressure. What do you must do ? increase the value if you want more pressure, and vice versa.
To give the diesel fuel does not ? sufficient to increase the Rail, starts from the map pedal, torque limiters and map injection.

Tonight when I return home, hoping to get to a decent schedule, we work on it and then place the mod.

ps: thanks to anke eisman, but 80bar or 80mbar?

[franco75]

that performance increase would you get?

[Nightwing]

that performance increase would you get?

looking at the maps ke propose the tuners on my ke part by a 200hp damage to an increase of 40hp + without other modifike, and I know ke are low of about x to have less riski.

[eismann]

then, very very roughly,

Pedal : 10%
close the egr obviously
Torque limiter 30%
86 points on the advance (2 degrees)
150 points of increase on the map injection
200 points for the turbo
and 800 points on the rail (80 bar)

cos? indicatively ? very seasoned.....but it should make the holes for the earth!

[franco75]

mmmhhhhhh to see in a second file, and how ? set away from the house, though ? as the 1.9 ? castrated by the limiters of diesel.
We proceed by steps, first make the map pedal modulandolo pretty well for that series is vomiting

[emilground]

maybe by tapping the limiters of diesel ( they are just after torque limiter), you can have a little important. Of course you should balance all of senn? the risks that face the smoke.

Raise the limiters of diesel, doesn't it ? a problem, but can you? make a nice map, even if not by touching them!

[emilground]

for? if you do not touch the limiters the deal? the maximum fuel injected sar? always equal to the maximum value of the surge protectors even raising the time. Then if c'? a way to inject more? diesel without touching the limiters I'd like to know it to study it. In the end, no oil in pi? the car does not go, c'? little to do. The increases in real you have with ir? diesel and ir? air

[eismann]

[emilground]

if you want to gain in speed? the final you need to power the pi? diesel (intended as the value to be overcome by raising the limiters). If, however, the speed? final do not care much about it is also good with a map "normal" since? for many ? pi? important that the car is quick and progressive and ? also just so?. The speed? tip rarely reach for? a little bit for them to increase the limiters, the right to the extension. There are people that with a small car wants to go more? other car pi? large cubic capacity.
Of course, on track, I give it for granted :p

I finally found a moment x mod. the pedal map, x now I'm the mod. only the first, but the other 2 made and sportB them I have to do the same? 2598

:confused: from the work nn I took the file, we tried again 2599

[franco75]

meanwhile, do all the maps of the DW, but not so, not aumentatre the whole curve of 15%, increases the area of the cut of the pedal gradually up to a 20% increase from the low values unless you want the pedal more sensitive. You should take advantage of that part of the pedal unused that you have

[eismann]

I'd give you a look but I still can't, am newbie in this forum! ;)

However, in my 1.9 f? the 240 (at the track) without raising the limiters of diesel, just working on timing and rail....a 2.4 cmq pu? become soooo bad!!!

you actually? was it intended my mod. since the values are so low, your perk? I want the pedal more? sensitive, now I have changed the map kn a gradual increase and then I fixed a p? 3D.
I am attaching the mod.;)

by k and we arrive early 80 messages, since the experience would have and all the tips ke you can give;)

congratulations beautiful beast:cool:, qnti cavallini you pulled out of your, and ke mod. mekkanike have done?

[eismann]

I have been many times l? l? to change it with a 2.4, just for that reason!

Mapped as the 2.4 ? a motorcycle!!! The latest Brera 200cv which I was dedicated, download the the odometer, no problems!
But the best part ? that f? 0-100 in a little more? of six seconds!

Ps: the middle and great preparation:D, I for the trim look to this summer, I wanted to focus on the Koni FSD, hoping ke them to do anke x 159

finally, sn was able to get to all of them, and 3, change in the table and then arranged in 3D, kme I said over my mod. was it intended in that way to get a quickness? response higher since the low.
what do you think of this mod.?

[James]

guardian, let the 3D, I do not say it is not important but to learn to interpret and modify the maps in 2D ? very useful, for the moment, not even I can look at you the file
