    MSD's Atomic EFI Master Kit is the complete carburetor-to-EFI conversion package for classic muscle cars and hot rods. Its self-learning technology continuously monitors and adjusts for smooth idle, quick starts, and strong throttle response, with the ECU and sensors built into the throttle body itself to minimize wiring and eliminate the need for a separate ECU. Initial setup and timing are handled through a compact handheld monitor that can stay in place for real-time monitoring or be removed once the system is running.
