About this app
TORQUEXPERT SD
TorqueXpert SD is an automotive diagnostics, OBD data logging, and vehicle performance measurement application designed for car enthusiasts, technicians, and tuning professionals.
Connect your Android device to your vehicle using a compatible Bluetooth 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 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.
