    I finished the tool and linked it to the OP. If anyone's interested, please feel free to have fun.

    Please inform me of any bugs found in the code or the documentation.

    Thanks for the work done.
    I agree, but he is or was a small engine mechanic and made the observation that small engines didn't have a spark curve. Although load is different they still ran fine. I asked him to use a Dyno spark table and see the difference, believe it or not the straight across the board table ran better and had better acceleration than that of the Dyno tuned one. Don't ask me why, it shouldn't work, but it did. Crazy! Like I said he removed all spark modifiers that he could find.

    Follow the instructions in the pdf using the sample files provided (in the .zip)(you can edit the sample files to put your own timing numbers in there), the program generates .csv files that you paste into your tune as explained by the pdf, it's very easy to do.

    ( For Linux: python is already installed. For Windows, you may have to install python, see here: https://www.python.org/downloads/windows/ )
