Hello all,

how do you manage to get what is locate where?

I read a few examples and how did managed to understand that the egr was there and not here, etc?

Opening the original file from the car with the winhex, por example?

Thank you already

your original file from car can edited with winols software.
You can read user manual here:

remap-peugeot-406-2-2hdi-4hx-pre-multiplex-t11

when you open it with winols some maps are located automatically with pressing key "F",
some maps have to be found manually - this takes some practise and skill.
