Want your car to sound like an expensive muscle car? Now you can! NOTE: DragFX requires a compatible 3rd party hardware interface. Supported interfaces include: – OBDLink WiFi – OBDLink MX WiFi – OBDKey WLAN – Kiwi 2 for iOS – Kiwi 3 The hardware allows DragFX to connect to your vehicle's OBD interface, so that the sound produced by DragFX accurately matches your engine's actual RPM in real time.
