MSD Atomic TBI Electronic Control Unit

The MSD Atomic TBI Electronic Control Unit (ECU), also called an engine control module or ECM, is a replacement control unit for MSD Atomic EFI throttle body injection systems. Atomic TBI systems bring self-tuning fuel injection to carbureted engines. They keep the simple, carb-style installation and add the drivability of electronic fuel injection.

Key Features:

• Replacement ECU made for MSD Atomic TBI throttle body fuel injection systems
• Replaces the original control unit to help restore the performance of your Atomic EFI system
• Part of the MSD Atomic EFI product line, which is designed around self-tuning throttle body injection
• Available in early and later versions that match the injector connector style on your Atomic TBI unit
• Backed by MSD's reputation for performance ignition and fuel injection components

If your Atomic TBI ECU needs replacing, this unit gives you a direct way to keep the system running as designed. Choose the version that matches your throttle body's injector connector. MSD's instruction sheet for the part number covers installation.
