Correct me if I'm wrong but that is a separate unit that needs to be purchased? What percentage of people actually use it? I never here much talk about it. How does one know how much ignition to reduce? CPS module is great but someone would still need to tune it and I doubt many go through the motions to accurately dial it in. I've done some research but I dont hear many people tweaking their CPS modules, correct me if I'm wrong, I'm willing to listen.
