5in Dual Range Tach W/Mem.

The AutoMeter 5-inch Dual Range Tachometer with Memory (Model 4499) is a precision analog tach engineered for high-performance engine monitoring in vehicles where engine speed data is critical to tuning and diagnostics. This ultra-lightweight electric tachometer delivers accurate RPM readout across dual ranges up to 10,000 RPM, making it suitable for both street performance and competitive applications where reliable real-time engine speed feedback is non-negotiable.

The 5-inch diameter face is sized for standard dashboard mounting configurations and features a silver face for clean readability under varying lighting conditions. The memory function preserves peak RPM data between sessions, allowing drivers and technicians to review maximum engine speeds and identify performance trends over time. The gauge mounts via standard dash installation, and at 1.2 lbs, adds minimal weight penalty to the vehicle—a critical consideration in weight-sensitive builds. The electric sensing technology eliminates mechanical cable installation hassles and provides stable, drift-free readings across extended operating sessions.

This tachometer is purpose-built for engine builders, performance tuners, and enthusiasts who require objective RPM data for carburetor tuning, ignition timing validation, and shift-point optimization. The dual-range capability accommodates a wide variety of engine configurations without requiring multiple gauge units. AutoMeter is recognized within the performance and restoration community for analog gauge reliability and readable dial design, and this model's memory feature adds diagnostic capability valuable in troubleshooting engine performance issues or documenting baseline performance before and after modifications.
