The Beep Commanderis the perfect solution for those who desire more speed steps than the usual 32. The Beep Commander is capable of operating in the 32-speed step mode for speed profile compatibility with existing engines. When desired, the Beep Commander can be switched to operate with 100 speed steps. The low-end speed control performance is noticeably improved in this mode of operation. Great for Pacific, Atlantic, and Switcher type engines etc. Includes R2LC, Prog/Run switch and all the wiring. Installation manual.
