FAQ

Do I need a shift-on-the-fly (SOTF) switch?
A SOTF switch is optional — it lets you change between tune levels while driving. A single tune does not require one.

What does an unlock cable do?
Some ECMs must be unlocked before a supported device can flash them. Whether you need an unlock cable or service depends on your platform and model year.
