    Again GM Vortec V6 Checksum.....

    Hello ! I already published this text in another column:
    Newly some days ago I made myself member in this interesting forum.
    I found it in the search to information on possible modifications of the software like they are used in The Chevrolet Blazer with Flash 28F400.

    My questions with regard to the adjustment of the Checksum:
    - in what direction can it be made
    - how do I calculate it
    - which is the formula
    - is there a program to do it
    - with what the changes are to be multiplyed .

    hoping that you can help me find the answers.
