SureFly SIM4P 4-Cylinder Impulse Coupled Magneto Replacement

Part Number: 08-17074

Overview

The SureFly SIM4P is a solid-state electronic ignition module designed to replace a traditional 4-cylinder impulse coupled magneto. It uses Hall Effect sensors to determine engine speed and position, allowing it to operate in either fixed or variable timing mode. In variable mode, spark advance is adjusted based on manifold pressure and RPM, with base timing set from the engine's data plate at installation. Because it relies on solid-state industrial-grade electronics rather than points, condensers, rotors or caps, the unit is designed to require no scheduled maintenance or overhauls.
