MSD Atomic EFI
Product images may differ from actual product appearance.
The all new Atomic EFI system was designed with two goals: simplicity and performance. Simplicity was achieved when MSD rewrote the industry standard for easy installation and programming. Performance is served through improved drivability from idle to full throttle blasts. The MSD Atomic EFI can be installed with basic hand tools in just a weekend! In fact 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. The Atomic EFI comes with a compact handheld monitor that allows you to select a number of parameters to match your engine combination. This will get the engine to fire up and it will start learning your combination immediately. No software programs to learn, and certainly no jets or idle mixture screws. In the end the Atomic EFI delivers the performance and drivability expected from an EFI yet with an installation so easy you'll have the rest of the weekend to cruise.
