Alfa 147 jtd 115hp with turbo 140cv

[mjet10]

Good evening I have a 147 115hp with fitted turbo 140 cv .....before mounting the turbo already had a map with the car here was discretatamente good but as soon as I mounted the turbo is a problem with the same map that I had with the original turbo after 3000 rpm, the required pressure tends to rise even if the map I require 1.250 bar and of the fourth and fifth to 4500 around I find myself at 1.6 bar and then take the average....I would like to do work at 1.5 bar fixed, but nn I understand because now with the map a little boost, I have problems....some of you, and never succeed??

I would say that you need to work with the VGT..
post some files to follow the whole speech..

Here is the file...the map, and purposely made half-informed and a bit deceived

I can't get with the pressure, and then it becomes useless to the exchange rate of the turbo which can withstand great pressures 1.6 1.5

I can not open the file,could you kindly put it back?
then I did not understand your problem.......
do you have a pressure of 1.6 and enter in recovery? you can safely change the limiters!with regard to the turbo and you have fitted,at a given pressure with the original you have a higher flow rate!then..............

Here is uploaded again...and the problem is that nn follows the pressure as imposed on I, and that after 3,000 rpm up to give damage... then after the 1.5 bar my map sensor nn reads more because it goes off the scale.

Hello mjet10...To resolve this problem, you need to change the pressure sensor (map) with one from at least 3 bar absolute and linearizzarlo in the map!

You didn't think of that pero I don't understand why even if I set the pressure to 1.3 after 3,000 rpm up the same this and the problem...

I 147 120 hp with ed16c39 I mounted the turbine 150 , the turbo pressure measured, followed, without the problems l objective . Sure that the vgt is working well ?

I checked everything several times...the only question that comes to me, if there any small loss of pressure and to compensate for salt pressure...could it be?
