Ok, i watched several vids on how to create the histogram/graph. Done. I have logged and collected data, done. Now when i go to the VVE dropdown and copy, paste special, calculate co-efficiant, the number change but it does bot change the cars ability to run. I am obviously missing a step. Please help. There is a dropdown the shows manifold closed/open, and then DOD. What am i suppose to do with that? I feel like its part of my problem
