Your log. Your dyno.
Load a CSV log from your diagnostic or flash tool, the Datalog Tool detects the channels, finds the full-throttle runs and calculates power and torque over engine speed from them. Two logs can be overlaid, for example before and after the tune. Everything runs in your browser, nothing leaves your computer.
Interactive demo
Click your way through. The demo runs with sample data directly in your browser, nothing is uploaded.
How you work with it
Load CSV
Separator, decimal comma, unit row and metadata are detected automatically. Without a time column, the tool assumes a fixed sampling rate.
Check channels
Engine speed, pedal, boost, speed, gear, temperatures, lambda, ignition and more are assigned. You can change any assignment.
Choose full-throttle run
The tool finds sections at full throttle in one gear. Enter vehicle data, and power and torque appear as a curve.
Compare and export
Overlay a second log as a dashed line, use cursor and zoom, save the chart as PNG or the data as CSV.
Features in detail
Channel detection
24 channel types via patterns in German, English, French, Italian, Russian and Turkish. Unknown columns remain selectable as raw channels.
Full-throttle detection
Sections with pedal above 85 % and at least 1.5 seconds duration, the longest run in one gear is used for the dyno.
Virtual dyno
Power from mass times acceleration plus air and rolling resistance, with drivetrain loss. Result as wheel and engine power over engine speed.
Chart with cursor and zoom
Own renderer: values at the cursor, zoom by dragging, legend to show and hide channels.
Two logs overlaid
Before and after in one chart, log B dashed. Differences in boost build-up or in the power curve are visible immediately.
Export
Chart as PNG for the customer, data as CSV for your own records.
Technical data
Who is the tool for?
Tuners
Check stage tunes on the log and give the customer a power curve, without a dyno appointment.
Workshops
Quickly check boost, temperatures and lambda against a reference log after a repair.
Drivers with a logger
Understand your own logs and trace changes.

Frequently asked questions
How accurate is the virtual dyno?
As accurate as vehicle mass, driving resistance and log quality. With correct data, the results are in the range of a chassis dyno, suitable for before/after comparisons.
Which logs work?
Any CSV file with column headers. Separator, decimal sign and unit row are detected by the tool itself.
Are my logs uploaded?
No. The tool calculates entirely in your browser. Only the usage is counted, not the content.
Can I assign my own channel names?
Yes, any column can be assigned to a channel type if automatic detection does not apply.
Is there a Windows version?
Yes, with the same calculation core. It is included in the Workshop Package.
