I am trying to modify the table labeled " VCT Spark", but when I save the file, other tables are changed as well. Is this normal? I installed a cam phasor in my L83 because I deleted AFM. I found a tuner that I could send my file to and they modified it to acomadate the phasor, and now I have a different tune I want to try but I need to duplicate the mod for the phasor into this new tune. I don't want to bother the tuner that helped me, so i'm asking for assistance to help me understand these table modifications.
