Revo SPS+ switch. £65 ono I am going for custom map so no longer needed. Used but in perfect working order. Not to be confused with the cheaper basic switches. This is the SPS that can be used to fine tune your map and load different custom map setting files. Can be connected to a computer to adjust the settings ready to load onto your cars Revo Map. Software and instructions are available to download from the internet. Manufacturers info: The Patented OBD2 interface is the ultimate compliment to Revo performance software. The Revo SPS gives the user the ability to switch between Revo performance modes and a stock performance setting via the vehicles OBD2 port. The new SPS has a preset stock mode, the ability to store three performance settings and the additional benefit of a security lockout program. Simply select a program, plug in, wait a few seconds, remove the select device and start the car. It's simple and there's no fixed switch to alert to any modification. The SPS delivers different levels of functionality depending on the vehicle it is used with, and whether variable switching is available in the Revo performance software NOTE: SPS is only functional on vehicles with Revo Performance Software already installed.
