SmartSpark LS Ignition Module

The SmartSpark LS Ignition Module by DAYTONA SENSORS is a plug-and-play ignition controller engineered for GM LS-series engine platforms. Designed for enthusiasts and professional tuners who demand precise ignition timing control, this module eliminates the guesswork from spark advance management and enables repeatable performance optimization across varying fuel grades and boost conditions. Whether you're building a naturally aspirated stroker or tuning a forced-induction LS variant, the SmartSpark LS delivers the electronic control needed to extract maximum efficiency and reliability.

This ignition controller features selectable step-retard functionality, allowing you to dial in precise timing curves without complex external wiring. The module is compatible with both 24-tooth and 58-tooth reluctor wheels, making it adaptable across a broad range of LS engine generations and cam sensor configurations. The compact design—measuring 4.5 x 2.3 x 6.8 inches and weighing just 1 pound—fits unobtrusively in engine bays with minimal installation footprint. Its proven reluctor tooth recognition ensures rock-solid trigger stability, even at high RPM, while the integrated circuit design prioritizes durability in high-heat engine compartments.

Engine builders, street rodders, and LS swap specialists rely on the SmartSpark LS Ignition Module to maintain tight ignition curves during dyno tuning and real-world driving. The plug-and-play architecture significantly reduces installation time compared to traditional distributor-based systems, making it ideal for retrofits and engine swaps where OEM ignition management is unavailable or incompatible. Compatibility with 24/58-tooth reluctor configurations means this single module works across multiple LS generations—LS1, LS2, LS3, LS7, LSA, and truck variants—without requiring multiple hardware revisions. Installation typically requires only basic wiring to your existing fuel pump relay or engine controller, and the step-retard feature can be tuned on the bench before final engine startup.
