Lightning Plus Delay Box

The DEDENBEAR Lightning Plus Delay Box (Model L2) is a digital cross-fire delay module engineered for serious drag racers and street performance enthusiasts who demand precision timing control. This compact yet robust unit solves a critical problem in high-horsepower vehicles: uncontrolled engine knock and detonation during aggressive acceleration or nitrous oxide injection. Whether you're running a turbocharged, supercharged, or naturally aspirated engine pushing significant boost, the Lightning Plus delivers the millisecond-level spark timing adjustments needed to keep your engine safe while maximizing power output.

At just 2.65 lbs and measuring 6.4 x 4.5 x 12.7 inches, the Lightning Plus integrates easily into engine bays with space constraints common in dedicated race vehicles. The module intercepts your ignition signal and retards spark timing by adjustable increments—typically in the range of 1 to 15 degrees—to prevent detonation while maintaining optimal combustion efficiency. Its digital architecture ensures repeatability across multiple runs, eliminating the guesswork of analog tuning and allowing you to dial in the exact timing curve your combination demands. The unit's potentiometer adjustment and programmable delay settings make it adaptable to various fuel octane ratings, boost levels, and nitrous jetting configurations.

Drag racers, bracket racers, and street performance builders benefit most from the Lightning Plus when running closed-loop fuel systems, carburetors with aggressive jet tuning, or when pushing engine limits beyond stock parameters. Installation requires basic wiring knowledge—connections typically interface with your distributor or coil pack ignition system—and mounting is straightforward using the compact footprint. DEDENBEAR's reputation for reliability in the racing community ensures this delay box will withstand repeated heat cycles and vibration in competition environments. For any performance builder serious about controlling detonation without sacrificing power, the Lightning Plus Delay Box is an investment in engine longevity and consistent elapsed times.
