View The Full Version : Alfa 147 115hp 8v failure overpressure turbo



Matty23p
Hello guys, as the title suggests I have a problem with the 147. Always goes in the failure of pressure-pressure in the turbo, we have tried to change the map to take it again, and there still is, the machine's pressure gauge is at 1.5 bar fixed and pike 1.7 logging in with the mes I read only up to 1.5. Below I have attached the map ori, and the mod (with the limiter reading moved) from the one that I knew I once "unlocked" the limiter reads up to 2 bar, I put in a 1.9 seen running at 1.7 maximum. Could someone help me understand if I'm wrong the mititatore to move? Or maybe there is some other problem? Thanks to all.

Matty23p even if you touch the single bit of the limitation "if and what you have touched"
not adapting the map real I doubt that you reach your goal..

The map and an overboost or geometry as you want to call..
I speak of the map turbo pressure and lim. as

not being able to view the map,I thought of that already? they were changed

but with the original you is the defect? not ? that you have a problem of the turbo.

Hello if I can help you, or read around on the forum that in order to have the certainty that the problem is not on the map you have to detach the absolute pressure sensor placed on the intake manifold you turn on the light on the charger but you can test if it is or not, let us know

have you tried to lubricate the piston on the variable geometry and clean the check valve geometry....
I was on my 156 I have done so and it seems to have resolved....

Often the actuator to an overboost, the one that is attached to the filter box... try to check the tubes and replace if necessary. I usually change position and I mount immediately behind the radiator where it is more fresh and above all more at your fingertips
