Did you try to write? Did you try to read again?

I try it again after battery off. Engine start and Ecu read.

How I can write the flashed file.
Do I need Immo off or Car Pin to write mapped Ecu ?

First you need to read flash 100%. You can upload a flash and I'll tell you if it's a good readed. If you write with Kess immo will be unchanged. And use a charger when writing!

Do not attempt to write this file! I compared they are very different. Probably a different version. Read Kess ID and write info (sw version and etc.)
