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. When it comes to the installation and initial setup, the Atomic Throttle Body Injection system is the easiest way to convert your classic car to EFI. As far as performance, the advanced self-learning technology of the Atomic is constantly monitoring and analyzing the engine’s operating conditions ensuring that you receive the best possible driveability. With the ECU and built-in sensors integrated into the throttle body, the Atomic has fewer wiring connections than any other system, plus there is no bulky ECU to mount. This design makes the conversion to EFI much easier to install and program while keeping things clean under the hood. 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 car guy 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.

Overview

Brand: MSD Ignition

MSD Atomic EFI Throttle Body Systems

These MSD Atomic EFI fuel injection systems are the perfect choice for anyone planning on converting from carburetor to fuel injection. They include a throttle body, power module (with wideband oxygen sensor), and handheld controller. The throttle body features an integral ECU built on the side, incorporating the TPS, MAP, IAT, and fuel pressure sensors, all in one location. Fuel delivery is provided by four precision 80 psi injectors featuring a stainless steel ball and seat metering method for maximum internal sealing. They also use internal fuel rails, providing a sleek appearance and removing fitting connections where leaks can develop. Atop the Atomic EFIs are annular booster rings that deliver superior atomization of the best fuel mixture, ensuring the best possible fuel delivery. Best of all, the MSD Atomic EFI fuel injection systems bolt directly to any standard square bore carbureted intake manifold and accept the same linkage as most carburetors. The 1.75 in. diameter throttle inlets ride in precision roller bearings for a smooth pedal transition. The Atomic EFIs’ unique TPS is a self-calibrating, non-contact sensor, which means that you don’t have to worry about configuring it during setup. The included power module is a remote mounted piece that handles all of the high-current loads. MSD’s CAN-Bus technology allows for a single, clean connection between these units and the throttle body mounted ECU. Control all of the MSD Atomic EFI fuel injection systems’ functions with the hand-held device. Initial setup takes about five minutes, and you’ll answer six questions about your specific engine. After the initial setup is complete, the device can provide you with engine data to help you keep your engine working properly. They also feature a removable micro-SD card to record and store data so that you can see what’s going on with your engine.
