If you tap and hold a tuning file received from your tuner, the app will display a short menu that selects the type of write that it will do.

Caution

  • While the read is in process, do not start the vehicle’s engine, turn the ignition off, or unplug the interface device. Keep your phone close to the interface device and connected to the Internet.

The options in this menu include:

  • Normal Write: This is the default type of write that occurs when you flash a tune file received from your tuner. If supported by the controller, this writes calibration data only. (However, some controllers only support a full write. For those controllers, this option performs a full write).

  • Full Write: In addition to writing calibration data, this flashes the controller’s operating system.

  • Restore Stock Calibration: If supported, this option retrieves the stock tuning data from your vehicle manufacturer and applies the stock tune. Although the option is displayed for all vehicles, it is only supported by a small number of vehicles. If not supported, this option does nothing.
