Hello,

If you have time you can test, dtc off + limp off (test)... If You decide to test, before writting calculate CS. Did edit with free stagex, dont have my pc at home, can't calculate it :)

I will spend some time trying more files, but only next saturday. This Vito is 160Km from me.
This ecu does not allow me to read by boot. So i need to dessolver the flash, and program...

Milicija, your solution don't allow the engine to start.
I found the solution, and tested it.
I share to anyone who needs
