8. Limits of the method

The virtual dyno is a tool for comparing files and catching problems early, not a measurement of a real car.

8.1. An estimate, not a measurement

Results come from a model of the car running your firmware in an emulator. They are an estimate, not a measurement, and the virtual dyno does not replace a run on a real dyno. A real car can behave differently depending on its condition: engine and turbo wear, fuel quality, sensors, intake and exhaust, clutch and gearbox, tyres and weather. Confirm the final tune on a real dyno before using it on the road.

8.2. Comparing reports

Each report names the emulator release that made it. The vehicle models are refined from release to release, so reports from different releases are not comparable. Compare the stock and the tuned image within the same release.
