Can i use file sent from ecu tunner to multiple ecu's ?

[digipan]

Guys/girls
hello,
i m wondering, there are two types of ecu according to ktag (clone) for my car,
supposing that my brother's car ( same year & same model ) has the same ecu e.g EDC17_C59,
can i use the file that the tunner will sent me for both cars?
Sorry if it sounds stupid but i am new to this.
Thank you for any kind of help you might give me.

That’s not possible on modern ecu types as checksums will be a problem. Also the stored injector coding will not match.

if you use original flex, cmd, kees. and makes virtual reading, if they are the same version, of course you can write

i use master version ktag (clone i guess) . is there anyway i can read the file and isolate the new program added, to add it myself to the other ecu? with no harm done?

so , me having a basic knowledge do you suggest that i should find out about checksums problems and software to repair it, or should i leave it for the pros to do it?
i had in mind to see the difference between the old and the new one and "copy paste" into the correct spots. you think i can make it?
once again i m sorry but i have little or no knowledge about ecu programming. sorry if i sound stupid

Why not attach your files?
It's enaugh compare 2 orginal files, if not the same one car of then not start or but start not drive good.

FIrst of all, read both ECU and compare Identification Data. After Reading ECU Compare both Ori files. If they same/identicak then you can use it !
