Thanks again ecuedit for support :) . I think that I have found the string but the adress is always 071B55. When I have wrote the car I haven't disconnected the plug of Egr valve(probable error) and when I turned on the car it has run for few second with a sound very bad noise like intake / exhaust but has turned off by itself and would not start more...Egr 100% open?
Unfortunately I have not tried to unplug and for reasons of time I rewrote original. During the holidays I have that car available and try again, however,I post the screen for safety ...ecuedit what do you think? Is it correct the string that I post?
I apologize again for my english :roll:

Hi
I got
EDC15c7
HN338
SN4629

I try to turn off EGR
EGR map is 71e80

I switched 71E61 on 0 ( in 8 bit) and EGR is ON.
It is correct address ?

Hi there,

I was looking for a solution to disable my Egr for my alfa 147 jtd16v and than I came here. I also have the euro 3 alfa 147jtd 8v with my Egr mechanically blanked ;-) when I check my dtc's with multiecuscan I have an error for Egr. now this topic is nice help for removing this error and get the job done! Going to give it a try! Meanwhile I'll keep searching for my 16v jtd solution :-D

This is my first attempt at editing, I think I found the EGR map (my only reference as absolute beginner are screenshots on the internet). I also think I found the switches.

Makes me wonder what all the switches do, the first is EGR on/off, second is turbo? (I think I saw this somewhere).
What do the rest of the switches do?

I added 3 images, can someone confirm I got it right?
EGR map (2D)
Switches
EGR values (is this correct? mg per stroke, offset and rpm?)

The ecu's bin is from 2004 (I have 2 ecu's, 1 in the car and one as spare/experimental ecu)
SW: 796
HW: 740

It's a small step, but I hope I'm at least getting something done!
