This tool is an estimate for workshop checks. Real dyno output can vary with drivetrain loss, correction method, gear selection and logging quality.

Workflow

From raw rows to a readable workshop overview.

The analyzer is designed for quick inspection, documentation and communication. It does not alter the source file and it is not a replacement for calibrated dyno testing.

Select or paste

Choose a CSV or paste RPM and Nm rows directly.

Detect values

Valid engine-speed and engine-torque rows are parsed.

Review peaks

Peak torque, estimated power and average torque are shown.

Download report

Export a scalable SVG curve report for the job record.

CSV processing is local to the browser. Selecting a file here does not create a file-service request or upload it to MG AutoTech.

Questions

AutoTuner log analysis FAQ

Which CSV columns are detected?

The analyzer looks for Engine Speed (rpm) and Engine Torque (Nm) columns. You can also paste simple rows in RPM, Nm format.

Is my CSV uploaded to MG AutoTech?

No. The selected file is read and processed locally by JavaScript in your browser. This tool does not send the CSV to our server.

Does the report show measured wheel horsepower?

No. Power is estimated from the torque values present in the log. ECU-reported torque can be modeled or limited and should not be treated as a calibrated chassis-dyno measurement.

What does the downloaded report contain?

The SVG report includes the source filename, torque and estimated-power curves, peak torque, peak power and their RPM points.
