Thanks also to You for the explanation.
Ok, recycle bin, my mpps and I try to buy a kess.
What is the difference? from master to slave?
I have read some discussions about problems with its software.
A secure version not 2000 euro exists?

With regards to read files with other devices, the original map of my car I read with galletto.
A tomorrow that will take? reassemble everything to sell it, the avr? difficulty? to write it with kess?

I gave a look around to get an idea of prices
The range varies from 150 to 2700 euro. Then I continued using it for personal and not-for-lucrative-to me it seems excessive to go beyond certain figures.
