 I just have a digital one, but I can get an analog if you think that would be good, or I can get something else. No, the digital one is fine, just as long as it'll refresh quickly. Do you have a way to do a graph, to read a graph? Do you have a way to read a graph on the scan tool? Yeah, I can graph the values on the scan tool. I was going to start with that. When you're going to try graphing, just put up the FTP value and nothing else.
