Two tools, one datalog. See the power your car is putting down, and find out whether the tune behind it is healthy. No dyno booking, no account, no fee.
Turns one clean full-throttle pull into a power and torque curve, corrected for the weather recorded in your log. Overlay several runs to compare — 93 against E85, before against after.
Needs: a sustained pull — 95% throttle, 3 seconds or more, at least a 4,000 RPM sweep in one gear.
Reads the same log for the things that decide whether a tune is safe: knock and DAM, fuel trims, air/fuel ratio, boost control error, intercooler heat soak, cam timing and fuel pressure. Comes back with a graded health report.
Needs: any datalog. It does not need a full pull — a log too short to draw a curve from is still worth checking for knock.
Upload a datalog once and run either tool, or both — the health report you download covers whichever you ran. Free to use, no account needed.

This tool is still being developed and calibrated. Some vehicles, gears, and datalogs can produce inaccurate results. Treat the numbers as a well-informed estimate, not a replacement for a real dyno pull.
Virtual Dyno turns a clean full-throttle pull into a power and torque curve. Tune Analyser checks the log for knock, fuel trims, boost control, intercooler and cam timing — and works on logs too short to draw a curve from. Run either, then the other; the health report includes whichever you ran.
Measured from your datalog
The virtual dyno is still under active development. Certain vehicles, gear selections, or noisy logs can skew horsepower and torque. If a curve looks wrong, tell us and we'll dig in.
