Not the same I know but, it was simple to set-up and it's easy to use. The display on the VI is a little large/awkward to mount in the car. I currently have mine velcro'd in the center console right now. Not elegant but, it works. As far as the S goes, it might be worth taking some measurements and seeing if you could fit the display it in the ash-tray for a "slick" looking install. Maybe someone else can comment on how the solenoid implementation compares to HKS's stepper motor technology of units past?
