Right now I'm running the MSD 6AL and HAD the blue HVC2 coil on, but switched to the FireCore CD Coil. I'll be making 2 time runs, then swapping to a 7AL2 and red HVC2 coil.



Unfortunately you are changing two things at once. Can you change the coil on the next run, and then change boxes? This is fairly typical of racers making multiple changes and not using a designed test. I did some statistical analysis years ago for a TAFC racer and at one race made several runs not changing anything, and then changed multiple things on the next run. It's impossible to sort all that out. It took me a years worth of data to figure out what he was doing with the fuel system because there were so many variables and so many duplicated runs.

Try using the 2 X 2 Factorial experiment in four runs.

Run #1 - Box A, Coil A
Run #2 - Box A, Coil B
Run #3 - Box B, Coil A
Run #4 - Box B, Coil B
