MSD Atomic EFI

High-Powered EFI Systems

The all-new Atomic EFI system was designed with two goals: simplicity and performance. With little preparation, installation can be started on Saturday morning and the car will make a cruise that night. This is due in large part to the ability to run a returnless fuel system so there are no modifications to the tank and no need to run another fuel line (in most applications). MSD incorporated the ECU into the throttle body to reduce the wiring and connections. MSD also moved the four main sensors inside the ECU for even less under-hood clutter and wiring.
