The all-new MSD Transmission Controller was developed completely in-house - evolving from the engineering expertise and proven performance of our Atomic EFI technology. In fact, the Atomic TCM is designed to integrate directly with the Atomic EFI when using Brainwave so you can modify transmission operation parameters from the same handheld monitor! Doing away with the need for sensor duplication, and an extra programmer, means less wiring for easy installation and a clean appearance.
