Checksum  is a Windows program  that allows you to apply a new checksum to a manually altered binary file, or display the current manufacturer and IEEE  checksums of a binary file.

This program is compatible with most pre-OBDII GM and Ford EEC-IV ECM files.

This is also very useful utility to check the validity of files, and to extract ID codes from GM binary files 

  • The Options menu allows setup for GM or Ford Checksum's.
  • The GM ID Byte, Scan ID words and the EPROM size are displayed for your convenience. 

Note: Binary source files must be an exact image of the original EPROM.
