okay here goes, I have a project 4.0 that I am working on and am wondering if I can use a SC computer to run it. I am working on a turbo kit and am thinking that if I can get an SC computer to work I can tune it myself. I don't have any problems if I need to re-pin the harness, or add some wires. The harness I will be using will be a 94' 4.0 explorer/ranger. Any info will be great...
