Cam, you can't pull a curve back out of the cdi and look at it after you put it in the cdi. you can only look at your base file that you save from making the curve. This is my experience + the engineers feedback at dyna from when I asked him. I have the cable and the program for programming the cdi, I also know how it works, and I make all my own curves for my cdi when we dyno test. If you lose your curve file that you custom made, your back to square one.
