TurboTune vs TorqueXpert

TurboTune is the companion app for the TurboTune device, designed to transform your driving experience. When connected to your TurboTune hardware through your car’s OBD2 port, the app reads live RPM data and uses it to generate responsive engine sound that matches how your car is actually driving. Acceleration, revving, and cruising are reflected instantly, creating a more engaging and immersive feel behind the wheel. The app also features a tachometer-style display, giving you a clear visual of your engine’s behavior while you drive. You can adjust the balance between engine sound and your music, allowing you to customize the experience to your preference. Setup is simple: plug in the TurboTune device, connect through the app, and start driving. Features: • Real-time RPM data from your vehicle • Responsive engine sound based on live driving input • Tachometer-style visual display • Adjustable engine and music audio balance • Simple connection with TurboTune hardware TurboTune hardware required. Vehicle compatibility may vary.

TorqueXpert SD is an automotive diagnostics, OBD data logging, and vehicle performance measurement application designed for car enthusiasts, technicians, and tuning professionals. Connect your iPhone to your vehicle using a compatible Bluetooth LE OBD-II adapter to access live vehicle data, perform diagnostics, record logs, measure power, and evaluate vehicle performance. KEY FEATURES OBD-II DATA LOGGING Record vehicle parameters in real time and save the data as CSV files for further analysis. POWER & TORQUE MEASUREMENT Calculate estimated engine power and torque using vehicle speed, engine RPM, acceleration, and other measurement parameters. PERFORMANCE MEASUREMENT Measure vehicle acceleration, including 0–100 km/h and other acceleration intervals. The combined use of OBD and GPS data provides improved measurement accuracy and stability. During a measurement, the application can analyze vehicle speed, engine RPM, acceleration, G-force, altitude, air temperature, and Density Altitude (DA). After each run, detailed graphs of speed, RPM, and acceleration are available for further analysis. VEHICLE DIAGNOSTICS Read and analyze diagnostic trouble codes (DTC), including stored, pending, and permanent faults where supported by the vehicle. ECU INFORMATION Access available ECU identification data, including VIN, calibration information, and other supported diagnostic parameters. DATA STORAGE & EXPORT CSV logs, measurement results, and diagnostic reports are stored locally and can be exported or shared for further analysis. ROAD SLOPE COMPENSATION GPS and vehicle data are used to determine road slope during power measurements. SUPPORTED OBD-II ADAPTERS TorqueXpert SD works with compatible Bluetooth LE OBD-II adapters based on ELM327 and compatible chipsets. For reliable operation, we recommend quality adapters such as: • Vgate vLinker MS • Vgate vLinker MC+ • Vgate iCar Pro • OBDLink MX+ Compatibility and available parameters depend on the specific vehicle, ECU, and OBD-II adapter. Cheap, unbranded ELM327 clones may have unstable connections, low communication speeds, or limited protocol support. A quality adapter is recommended for data logging and performance measurements. IMPORTANT INFORMATION Power and torque results are calculated estimates and depend on vehicle data, measurement conditions, and parameters provided by the user. Results are intended for informational, diagnostic, and comparative purposes and are not certified dynamometer measurements. Performance measurement results also depend on measurement conditions, GPS signal quality, available OBD data, and the equipment used. Always use the application safely. Do not interact with the application while driving. Use a passenger to operate the application when necessary, or perform required actions only when the vehicle is stationary. TorqueXpert SD is designed for automotive diagnostics, data analysis, power measurement, and vehicle performance evaluation.
