RCEXL Single Twin L-V 3W Radial Ignition Timing Device / Testing Kit

The RCEXL Universal Sensor Timing Device is an essential tool for setting and testing ignition timing precisely on your RC engines. Designed to work seamlessly with any RCEXL or RCEXL CH-made CDI ignition system, this device supports both single and dual output sensors, making it compatible with a wide range of engine configurations.

Ideal for single and twin-cylinder engines with even-fire patterns, the single sensor output (3-pin connector) setup covers 2 and 4-stroke applications. For more complex engines — such as multi-cylinder, uneven twin, inline V, or radial engines with 3, 4, 5, 7, or 9 cylinders — the dual sensor output (4-pin connector) is perfect for ensuring precise ignition timing across all cylinders.

This timing device is a must-have for hobbyists and professionals who want to maintain optimal engine performance according to OEM specifications.

Key Features:

• Compatible with RCEXL and RCEXL CH CDI ignition systems

• Supports single output (3-pin) and dual output (4-pin) sensors

• Ideal for single & twin cylinder and multi-cylinder radial or inline engines

• Works with 2-stroke and 4-stroke engines

• Enables precise timing adjustment to OEM specs for better engine performance

• Compact and user-friendly design for field or workshop use

Important Note:

Dual sensor output timing setup differs significantly from single sensor output. Please consult your engine or ignition manual for correct timing procedures.
