MSD Ignition MSD2910-2BK Atomic 2 EFI Throttle Body System Tps Map Iat Iac Power Module Kit

MSD Atomic 2 EFI throttle body systems feature four 100 lb./hr. fuel injectors that can support up to 650 hp naturally aspirated or 635 hp on forced induction applications.

The Atomic 2 ECU is capable of fuel map self-learning and ignition timing control—improving idle stability, drivability, and wide-open throttle horsepower! They're designed to fit on a 4150 intake manifold, with ample clearance for factory air cleaners. These systems provide the performance and drivability 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 2 will support ignition timing through the ECU and you have a win-win combination. Initial timing is handled through a compact hand-held monitor where you simply answer a few car guy questions about your engine—and you're off and running! Atomic 2 systems are available in a raw aluminum or black ceramic finish.
