MSD Atomic EFIAtomic makes EFI easier than easy
MSD’s Atomic EFI systems were designed with two goals in mind - simplify the installation and improve overall performance. Simplicity was achieved with less wiring and fewer connections to ease the installation process as well as programming the system through a compact handheld monitor. Performance is served from idle to full throttle blasts with crisp throttle response and comprehensive driveability improvements.
MSD offers two Atomic EFI systems, a Throttle Body system designed to replace a carburetor and the Atomic LS, for the popular Gen III/IV GM powerplant. Both systems are based on self-learning EFI technology to deliver incredible performance and reliability along with MSD’s promise of simplified installation and initial setup.
Atomic TBI injection
- Less Wiring, Fewer Connections
- Self-Learning technology
- Simple to setup - no laptop required
- Capable of running with boost or nitrous
- Ignition timing control
- Improved overall driveability including idle, throttle response, starting and cruising
Today, there is no reason your muscle car or hot rod shouldn’t start, idle and cruise down the road as smoothly as a newer car. The Atomic EFI provides the performance and driveability benefits that you expect from fuel injection. Quick starts, smooth idle and great throttle response just to name a few. Combine the fact that the Atomic will support ignition timing through the ECU and you have a win-win combination.
Initial timing is handled through a compact handheld monitor where you simply answer a few carguy questions about your engine and you’re off and running! This monitor can be removed from the car after it’s running, or left in place so you can monitor engine parameters in real-time.
The Atomic TBI system will turn the car you love into the car you love to drive.
Atomic LS injection
- 8 connection installation
- Replaces standard square bore carburetor
- Controls ignition timing
- Integrated ECU and sensors
The GM LS-based engine has been embraced by hot rodders, muscle car fans and racers alike. The lightweight and compact engine produces plenty of power and fits easily in many engine compartments. However, trying to retrofit the factory EFI system into a street rod or muscle car creates a number of challenges from wiring to programming.
The massive factory ECU is not only a hassle to mount, but the sheer amount of wiring that goes along with it is simply overwhelming. By integrating the ECU onto the fuel rails MSD has eliminated the bulky ECU and tangled mess of a wiring harness. The self-tuning technology of the Atomic system allows the average do-it-yourself hot rodder to easily wrap up an LS engine transplant. Initial setup is a breeze with the supplied handheld monitor and by simply answering a few car guy questions during the initial setup, your Atomic LS’d project will be ready to drive.
- Integrated fuel rails and ECU
- Patent pending wiredless technology reduces wire
- Supports single/dual throttle body
- Automatically recognizes 24 or 58 crank trigger wheels
There is no reason to settle on just three gears or the kickdown linkage of an automatic transmission with the number of electronically controlled four speed automatics that are available these days. MSD will take the mystery out of setting up or programming an automatic trans with the Atomic Transmission Controller.
Atomic Airforce intakes
- Adjust shift points
- Adjust torque converter clutch behavior
- Select different levels of shift firmness
- Auto-shift and manual shift modes
- Dyno mode to deliver repeatable results
When you’re serious about power for your LS or new LT1 engine, call in the AirForce! The all-new MSD Atomic AirForce intake manifold delivers improved airflow and distribution to improve the performance of stock and modified engines.
The unique bell-mouthed runner entrances maximize airflow and minimize shrouding - all while optimizing the available plenum volume for an unobstructed flow path over opposing runners. The polymer molded 2-piece design allows for easy access to the runners for porting.
Atomic AirForce accepts an OEM or 103mm throttle body as well as stock or aftermarket fuel rails including MSD’s Atomic LS EFI system. The intake bolts on and is supplied with new gaskets and hardware for a direct bolt-on package.
