How to write to Simos 18.1 (Audi S3 2015 CJXC)

[outrage_uk]

Which tool can successfully write to this ECU?

I have tried Kess clone (5.017 / v2.47) but it apparently does not write 4.5 Mb files. :culpability:

Thanks.

cmd genuine, kess genuine, most all genuine write. or make ecu out. if go wrong on expensive car with clone tool then very costly.

4,5 mb is only for genuine tool, the clone support only 4 mb.....each 4,5 mb file need only to be cutted from address 400000 to 480000

If you split the file, how do you write both of them using Kess?
