check solder pins

i have checked the solder pins and all are good except for 1 the pad has lifter from the board but i have managed to solder it back to the eeprom, but still the same ? is my original read a good read ? and does it 100% need to be read/written in 16 bit the chip says S93c86 and i am reading it under 93Lc86 x16 is this correct ?

reprogram the eeprom with the original file, and check if everything is ok, so you know if the problem comes from the modified file or no

Just thought i would let everyone know i have sorted the problem it, the problem was the file that was changed was incorrect, i posted a 8bit file and a 16bit file not knowing which one you guys needed to change and the file was changed for me was a 16 bit when in fact i needed a 8bit file changed hope this helped someone in the future and thank you for trying in the first place for me much appreciated

You better change your name.

You are not the Dashmaster if you think you need a 8bit file for this Nissan.
