Macbook Pro 2011 EFI read incompleate

I am having trouble with the bios chip because I read de eprom but the size of the bin file is to small compare with the clean bin that I downloaded here, and when I tried to write the eprom with the clean bin it says that the extra data in the clean bin file will no be written in the eprom, any solution to this?

Hello, please explain me how you read chip?
What is the program used? ( perhaps that the model of chip is notcorresponding with the program show??)

it's a program issue?
it's a chip issue?

I use the CH341A program, and dectect the chip and read it , when I am editing the bin, i can´t find the line where is the serial number and when i compare the clean bin an the one that I read from the computer, the one in the computer have a lot of lines missing compare with the other and if I try to write the clean bin It says that the aditional data will no be written

Please take a picture and post it!!!
What is the model of EFI appears with the CH341A programmer?
