The DiabloSport PredatorX is an app-based mobile tuner that pairs an OBDII dongle with the PredatorX smartphone app for iOS and Android. The dongle can stay plugged into the vehicle full time, and tuning changes, real-time data monitoring, data logging, and reading or clearing diagnostic trouble codes are all handled from the app. It ships preloaded with power-adding tunes for multiple octane levels plus transmission tunes where applicable, and exposes end-user parameters such as speed limiter, tire size, rev limiters, and idle speed. Additional vehicle licenses can be purchased to tune more than one vehicle from the same device.
