Alfa Romeo GT 1.9 JTDm 150HP EGR OFF goof

[user202]

Hi guys,

I will make my first touch soon with ALFA ROMEO GT with Bosch EDC16C39 1.9 JTD 150HP (2005)

I should make EGR off I made a sample file from ORI database, I did EGR closed by 4 hyst maps.
Is it enough to do with or need to remove P400 class Fault codes?

Or should I use EGR Governor switch to disable it?

By the the way I would use BDM fully read and write with KTAG because as I know Alfa EDC16 takes 40min to read by OBD.
Does anybody has an experience to write OBD Alfa with KESS, I have Kess EU made quality purple pcb


Thanks!
