    hey guys so im in the midst of doing a lot of rewiring on my chevy nova with fast xfi 2.0. I currently have an msd 6btm box wired in. I want to streamline and clean up the wiring harness as wellasget rid of stuff I don't need for simplicity. somy question is, do I need an ignition box to run my car or doesthe xfi handle spark output on its own and if I don't need it are there any benefits to keeping it. thanks guys

    You MUST use a CD box. All the XFI does is create a trigger signal called the points output.
