FGTech - problem with writing MEV17.4

[omglol]

I read MEV17.4 with FGTech v54 OK, but now I want to write it. The damn thing says the checksum is not supported and it stops the operation. Suppose the checksum is already corrected, is there a way to turn if off during writing?

Read file is not with correct dimension. If I remember read file with that tool is 50% biggest from real file dimension.
Dont write that file ecu will be erased and cant be write.
All clone tools is non safety to work.

Post read file I will check to you
