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: The options other than “Normal Write” in this menu trigger types of file writes that are not recommended except in certain cases in which they are required for troubleshooting. Use only as directed by HP Tuners Customer Support or your tuner.

The options in this menu include:


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).


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


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.
