Description
2TExc is the complete professional toolset for designing, analyzing, and tuning 2-stroke engines. From expansion chambers to diffuser and baffle cone geometry, port and ignition timing, intake resonance, gearing, and powerband – every calculation is precise, fast, and based on validated real-world formulas.
Built for tuners, mechanics, racers, and enthusiasts who demand engineering-grade accuracy. Suitable for classic engines, modern racing setups, and custom-built projects across moped, scooter, motorcycle, kart, and competition engines.
Unlike generic calculators, 2TExc covers the entire two-stroke workflow: exhaust design, reverse analysis of existing systems, intake resonance tuning, port and ignition timing evaluation, and drivetrain matching. All modules interact logically for reproducible, consistent results.
Key Features:
1. Exhaust Calculator – Full expansion-chamber geometry, tuned length, cone angles (diffuser & reflector), diameters, 1- & 3-stage layouts, stinger plus restrictor. Precisely calculate resonance behavior and wave timing.
2. Cone Design – Build diffuser & baffle cones, headers, and transitions. Convert data to flat sheet metal to exact final exhaust components.
3. Reverse Exhaust Calculator – Calculate tuned RPM, chamber volume, ratios, and angles from existing exhausts. Compare, verify, and optimize performance.
4. Ignition Timing + Gas Wave Calculator – Convert ignition timing BTDC from degrees to millimeter. And Calculate exhaust pulse velocity under variable temperatures using proven formulas.
5. Port Timing + Reverse Calculator – Analyze exhaust, transfer, boost, and intake timings for optimal RPM tuning and powerband shaping. Alternatively, enter the desired port timings to get the exact port dimensions in millimeters.
6. Intake Resonance – Align intake pulses with exhaust harmonics for improved cylinder filling and throttle response, including boost bottle volume and resonance frequency.
7. Gear Ratio Calculator – Set ideal gear ratios, RPM transitions / RPM matching, acceleration, and top speed.

Nouveautés de la version 1.1.0
BIG UPDATE:
• IGNITION: Convert ignition timing BTDC from degrees to mm (formerly: Gas Wave -> now below Ignition Timing)
• PORT TIMING: Reverse -> From desired port timings to port dimensions in mm, incl. Transfer Ports A & B + Aux Exhaust Ports
• EXHAUST: Volume/displacement ratio
• CONE DESIGN: Choice between cone height / angle & info on building a rounded cone without length change
• Limits for pistons at TDC adjusted (empty / unknown values are treated as 0; negative values are possible)
• Updated UI & styling
• Adjusted paywall & module purchase text
• Minor bug fixes & performance improvements
