Multifunctional Integrated Design One machine integrates GPS OBD to read the ECU data of the entire vehicle and switch between multiple interfaces to get more functions Accelerated test The acceleration of 100 kilometers takes some time, and the driving is stronger. It takes time for the car to accelerate from 0 km/h to 100 km/h, which is an important reference point for the power of the vehicle! Turbocharger test Real-time display, intuitive representation of powerful engine performance! Turbine manometer can display data in real time. Note: No data for models without turbocharging Brake test Safety, as always, is important! Time-consuming car speed from 100 km/h to 0 km/h, important reference data for braking performance! =OBD mode= Speed/clock/speed/water temperature/voltage/fuel consumption/driving time/single mileage/compass/altitude/ Turbo pressure/acceleration test/brake test/fault correction =GPS mode= Speed/clock/travel time/number of satellites/altitude/single mileage/compass/turbo pressure brake Package includes: 1 head up HUD display
