Limiter pressure Turbo Alfa 159 2.4 jtdm

[Nightwing]

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

thanks james, terr? this the council of the increments in points absolute, thinking about it in this way, you should take + under the control of the mod.

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.
Escapes me perk? the values are pi? high to a low number of revolutions
ps:
To increase the diesel, I have to increase the rail pressure, right?

To increase the diesel, pi? that increase the rail, (which v? well you increase it but IMHO max 80 bar), I would increase the pedal and injection times...

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.

thanks franco the operation of the Vgt would have described above, reminds me of the principle of operation of variable-speed? of the scooter.
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.

Tecnikamente seen if I put the downpipe and the pipe luca stanca, I would like to point to qlkosina in pi?

[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
