Your AutoCal device will contain a single tune file per order. Depending on the setup, the tune file will offer either 4 or 5 selectable tunes, which can be switched using the provided CSP4/CSP5/DSP5 switch.

Each tune is programmed for a particular vehicle associated with the AutoCal device. If you wish to use the AutoCal for tuning multiple vehicles, please reach out using our Contact Us page here to inquire about obtaining additional VIN licenses and tune files tailored to each vehicle.
