If you decide to purchase, here’s what you’ll actually get:

| Feature | Description | |---------|-------------| | 3D Engine Viewer | Rotate and zoom into a fully modeled Simson two-stroke engine. | | Tuning Simulation | Change cylinders (e.g., 60cc, 70cc), exhausts (e.g., AOA, Giannelli), and carburetors (14N, 16N, 19N). | | Performance Graphs | Realistic power (PS/kW) and torque (Nm) curves based on mathematical models. | | Gearbox Simulation | Test different sprockets and primary drive ratios. | | Print Reports | Generate a complete tuning plan for your mechanic. | | Export to PDF | Share your setup with friends or forums. | | Language | German and English interfaces available. |

Note: The software does NOT include real engine sounds or road riding simulation—it’s a pure tuning configurator and learning tool.

A: Officially, Windows only (7, 8, 10, 11). Some users run it on Mac via Wine or Parallels, but not officially supported.

A few German Simson forums (e.g., SimsonForum.de) offer browser-based tuning calculators. They lack 3D graphics but can calculate power estimates and fuel mixtures.
