Want your car to sound like an expensive muscle car? Now you can!

DragFX requires a Bluetooth OBD adapter. The adapter allows DragFX to connect to your vehicle's OBD (On-board Diagnostic) interface to allow the sound produced by DragFX to accurately match your engine's actual RPM in real time.

Without the OBD adapter a slider allows manual control of the RPM to preview the available engine sounds.
