Calculated estimates depend on vehicle data, conditions, adapter quality and user settings. Not a certified dyno measurement.
Use a flat, safe road and repeat the same gear and conditions for comparable runs. Road slope, air temperature, altitude and Density Altitude can be considered when the required data is available.

POWER MEASUREMENT93–100% confirmed accuracy
With correct measurement setup and accurate vehicle data, TorqueXpert SD delivers confirmed accuracy of 93–100% compared with a real dyno bench. Unique calculation algorithms combine OBD and GPS data for a detailed power and torque estimate.
APP TOKENSMost tools are free.
Most tools are free.
Use Tokens for advanced analysis.
Start with five Tokens after registration and use them when you need deeper results.
Added to your balance after registration.
One Token for a calculated power and torque graph.
Two Tokens for a detailed AI diagnostic report.
One Token costs only three US dollars.
The majority of everyday app features are available for free. The app shows the Token cost before a paid analysis starts.
AI DIAGNOSTIC REPORTFrom fault code
From fault code
to clear next step.
TorqueXpert SD uses unique algorithms to analyse several DTC codes together, identify relationships between faults and create a detailed report for the specific vehicle.
- 01Detailed error description in plain language
- 02Probable causes and connected fault relationships
- 03Diagnostic priorities and repair options
- 04Vehicle, VIN and ECU information when available
Each report can include a structured explanation of what the error means, why it may have appeared, what should be checked first and which repair paths may resolve it.

FAQQuestions drivers
Questions drivers

Clear answers about downloading, adapters, Tokens, reports and measurements.
Where can I download TorqueXpert SD?
The Android application is available through Google Play. The iOS version is coming soon and will be announced through the TorqueXpert SD community channels.
What do I need to get started?
You need an Android phone or, when available, an iPhone, a compatible Bluetooth OBD-II adapter and a supported vehicle. Insert the adapter into the vehicle's OBD-II port, enable Bluetooth, open the app and select the adapter.
Which OBD-II adapters are recommended?
We recommend Vgate vLinker MS, Vgate vLinker MC+, Vgate iCar Pro and OBDLink MX+. These adapters provide a more stable connection and better data speed than many cheap ELM327 clones.
What is ELM327 compatibility?
ELM327 is a common OBD-II adapter platform. Compatibility depends on the adapter chipset, vehicle protocol, ECU and available PIDs. Some low-cost clones may connect but provide unstable Bluetooth, slow data or incomplete parameters.
How accurate are power and torque estimates?
With correct measurement setup and accurate vehicle data, TorqueXpert SD provides confirmed accuracy of 93–100% compared with a real dyno bench. The calculation uses OBD and GPS data, vehicle parameters and the measurement settings entered in the app.
What can the AI diagnostic report explain?
The app can read stored, pending and permanent DTCs when supported by the vehicle. Unique analysis algorithms combine the codes, vehicle information and ECU data to provide a detailed description, possible causes, relationships between faults and repair options.
How do Tokens work?
After registration, the user receives 5 free Tokens. Most everyday features are free. A power and torque graph costs 1 Token, an AI diagnostic report costs 2 Tokens and 1 Token costs $3.
Can I use the app while driving?
Do not interact with the application while driving. Configure the measurement while stationary or let a passenger operate the device. Always choose a safe, legal road and follow local traffic rules.
Where are my logs and reports stored?
Logs, measurement results and diagnostic reports are stored locally and can be exported or shared. Available fields depend on what the vehicle ECU and adapter provide.
