Sorry, I can't understand the meaning "which read method" & "when prompted"
Please Explan tome.

to save ROM Image, I couldn't.

When you select ‘read from ECU’ in Ecuflash (or the read icon), a list box will appear from which you must select the correct read method that corresponds to your vehicle. If the incorrect read method is chosen, the download will fail:

Dear "merchgod"

Thnak you for a response every time!

Well, After I selected ‘read from ECU’ in Ecuflash , I could select the read method that corresponds to my vehicle.
and 100% could read (downroad) any table from my vehicle.
and I can change number in some items(speed limit & boost table. etc)
So, Read memory is O.K.
"but" Just can't save the Rom in my P.C.

Yes, I use Ecuflash version 1.31.

Please help me.

When you read a rom from your ecu with Ecuflash, if it is supported (which it is if you are able to immediately view tables), then a copy is already saved. Go to File->Options and look at "rom file directory" and this is where it saved your file. You could also choose File->'Save Rom As' after you are done reading and save it to the directory of your choice.

If the rom file is NOT supported by the definitions, then you will be given options for which you should choose 'continue to use this rom without definitions' and then save the file (file->save rom as).

Dear my teacher.

I know about "rom file directory" . thank you.

but how to be given options for choose 'continue to use this rom without definitions' ?
when and where can I choose?

I tryed to "save rom as" also for change file name, but I couldn't.
the Log said
"can't open image file for writing."
Do you know the meaning about this error log?

I was talking about reading, NOT writing (flashing). Sounds like you are trying to open a file on your hard drive that in not a valid rom file.

Hello my teacher.

-> was talking about reading, NOT writing (flashing).

Oh. I'm sorry.
Could'nt I read memory Completely?
I don't think so.
I could save log befor, so I will try to show log.

thank you.
