MSD Atomic TBI, Hand Held Module Only

The Atomic's handheld monitor gives you access to the Atomic EFI setup for your application! This monitor, combined with the self-learning technology from the internal ECU, eliminate the need for a laptop. Simply push the joystick left, right, up, and down to move through the options. Within minutes the setup will be complete! Plus, the handheld will act as a dash to display all that is happening in your new Atomic injected engine such as coolant temp, TPS, air/fuel ratio, rpm, IAC count, injector cycle and much more.
