Switch Compatibility FAQ
Will this work with Bully Dog tuning?
No. The tuning must specifically support switch-on-the-fly (SOTF) functionality.
Will this work with a Bully Dog BDX tuner?
Yes, as long as the vehicle’s tuning file supports SOTF (Switch-On-The-Fly).
I ordered this switch with a tuner — will it also work with CAC-based tunes? It’s currently wired to my fuel temperature sensor.
Yes. This is the same switch. On Ford applications, it can be wired into either the Fuel Temperature sensor or the Charge Air Cooler (CAC) sensor, depending on how the tuning is set up.
