HP Tuners 6-Position Diesel Switch (H-M04-00) is a rotary control accessory designed for Switch on the Fly functionality on supported diesel applications. It allows quick selection between a stock calibration and up to five custom tune maps using a simple six-position dial. Built with a knurled aluminum knob and clearly marked position indicator, the switch connects through a 5 ft OBDII pass-through cable for clean in-cabin installation. When paired with HP Tuners Switch on the Fly operating systems (sold separately), it enables controlled calibration changes without reflashing, making it suitable for professional tuning environments and advanced diesel setups.
