Advanced Write Options

Tapping and holding a tune file received from a tuner will display a short menu. The menu allows the customer to select the type of write that the app 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. Customers should use only as directed by their tuner or by HP Tuners Customer Support.

The options in this menu include:

Normal Write

This is the default type of write that occurs when a tune file is flashed. 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 the 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.
