CAPABILITIES
The Atomic TBI is designed to install on a standard square bore intake manifold flange. It is a self-
tuning EFI system that continuously adjusts after the basic configuration is complete. There is no
laptop programming. Base on the engine descriptors that you input during the initial setup, the Atomic
will automatically create a base fuel map to get the engine running. Once the system is started the
self learning technology will optimize those maps resulting in the best performance possible. If you
drive through altitude changes, temperature swings or other factors the Atomic will adjust accordingly,
on the fly. This ensures that your engine will produce excellent driveability at all times, even from the
sunny coast to the cool mountains.
There three main components of the Atomic TBI; the throttle body, the Power Module and the Handheld
Monitor. The ECU of the system is built into the passenger side of the throttle body and there are
several sensors integral to the unit including the Throttle Position Sensor (TPS), Manifold Absolute
Pressure (MAP), Intake Air Temperature (IAT) and the Fuel Pressure Sensor.
Power Module: The Power Module of the Atomic LS is the communication
hub of the system and provides the high current fuel pump circuit
and other input/outputs for optional features. The unit has two ports
for the MSD CAN system as well as a wiring harness. There are
connections for the WB02, the Handheld Monitor as well as power
and communication to the integrated fuel rails.
Programming: To program the Atomic for your specific engine application,
there no need (or method) to connect a PC to the system. All of
the programming is performed through a simple to use Handheld
Monitor. The Monitor simply plugs into the Power Module. Once the few initial setup selections
are answered and the engine is running the Monitor can be removed or left connected. When
it is connected, there is a Dash and Gauges screen that show engine parameters in real time.
Fuel System: The Atomic TBI system can be used with return or returnless EFI system. Review the
Fuel System Information section starting on page 3 for detailed information.
Wide-Band 02 Sensor: A Wide-Band 02 sensor is supplied in the Atomic TBI Kit.
This sensor is responsible for constantly monitoring the exhaust gases and
relaying that information to the ECU where adjustments are continually made
to the fuel delivery in order to meet the air/fuel targets. Only one sensor is
required. Page 5 outlines sensor installation.
Trigger Signal: The Atomic TBI requires an rpm/trigger reference signal to operate.
This signal be a 12-volt square wave reference signal from the tach output of
an MSD ignition control or it can be achieved when connected to coil negative
with breaker points, GM HEI or Ford TFI inductive based ignition system.
Timing Control: The Atomic TBI is capable of controlling the ignition timing. To use
this function an MSD 6A or other ignition control must be installed. The distributor must also
be locked-out. There are settings for Idle timing, Total advance and Vacuum advance through
the handheld monitor. Pages 16-19 explain the timing control setup in detail.
Rev Limiter: A fuel controlled rev limiter can be set through the Atomic. When the engine rpm reaches
the programmed value, fuel will be cut off to achieve the desired limit. Any ignition related rpm
limit is set and acts independently of the Atomic.
