Washburn's FIS2-001 Fuel Injection System — Carb-to-EFI Conversion for Type 1 VW Engines
The FIS2-001 Fuel Injection System conversion kit is a complete fuel injection solution for Type 1 Volkswagen engines. It replaces the carburetor with a modular system that an experienced mechanic can install, and its ECU controls both fuel and ignition timing. It ships pre-programmed for a 1600 engine and can be reprogrammed for larger engines by the end user. Beyond optimizing fuel and timing, the system adds a high-idle mode for cold start and compensation for elevation and engine temperature.
This kit provides significant performance gains: dyno testing showed an 8-HP gain (46 to 54 HP) and an 11 ft-lb torque increase (79 to 90 ft-lbs). The engine starts right up when cranking without touching the accelerator, and when you do hit the gas the response is transformed — instant acceleration on demand and smooth, strong power across the entire RPM range. The added O2 sensor also improves fuel economy.
Vehicle Fitment
- VW Beetle, Bus, Karmann Ghia, Thing & Type 3: All years, Type 1 engine-based
