To find the root code required to unlock an H&S Tuner, perform the following procedure:
- Hit The TOP LEFT button to open the main menu.
- Scroll down until you see the SHOW SETTINGS sub-menu, and then press the corresponding button to select it.
- Hold down the BOTTOM LEFT HAND BUTTON until the unit beeps - this may take up to 20 seconds.
- After it beeps, release the button and it will pull up a 4 digit code at the top of the screen. This is your Root Code.
IMPORTANT: AFTER RECEIVING YOUR UNLOCK CODE, BE EXTREMELY CAREFUL TO ENTER IT IN CORRECTLY AS IT IS A ONE-TIME USE CODE.
