Lingenfelter LNC-003 2-step adjustable launch controllers allow you to direct primary and secondary rpm limit settings.

These dual spark-based rpm limiters will help provide consistent launch rpm, as well as the ability to load the engine to help build additional boost off the line. They can also be used as adjustable individual cylinder rpm limiters—especially useful with auxiliary fuel control systems where it's nearly impossible to make sure both the factory and auxiliary systems turn off fuel at the exact same time. Make your LSX-based engine and ignition system really perform at the drag strip with Lingenfelter LNC-003 2-step adjustable launch controllers.
