About this app
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. Hear the sound of a turbocharger blow-off valve when your RPM drops below a configurable threshold. DragFX can also provide an audible indication when 3 different RPM thresholds have been exceeded to assist in shifting gears. You can even listen to music while also enjoying the sound of a souped-up engine! Without the hardware, a slider allows manual control of the RPM to preview the available engine sounds.
