Go Fast Bits introduced the atomic boost controller as a manual answer to the ECU. It can be a more affordable alternative to a tune for cars with older turbos, as well. Either way, the premise behind the atomic boost controller is to offer simplicity. Instead of having to manage digital components, you can set your boost level by hand any time you want. However, it is important to have a reliable starting point. You must know what the factory levels are before you set your atomic boost controller. This will help not only with gaining better results, but it will also protect against engine blowout.
The main attraction for many is the ease of installation. The boost controller does not require reprogramming of the electronic control unit (though for some vehicles it may help). There is no rewiring necessary. It is actually simple to connect using the included components. All it takes is connecting the hoses from the part to the wastegate actuator and to the boost source, respectively. Once it is set up, you can adjust using the Allen key that comes with the unit. This is how you will increase or decrease the boost. You may need to test it out several times to find your desired level.
After you have the pressure figured out, it’s time to see how it works. The turbo boost controller is designed to keep the wastegate closed long enough to accumulate more boost. This also helps the turbo spool quicker. As the pressure builds up, the boost controller manages the increase, resulting in more horsepower. It can be used for safety, as well. So long as the amount of boost is properly regulated in accordance with your car’s engine capability, you will not have to worry about your Go Fast Bits controller contributing to lag during idle or other issues.
While this part is not exactly universal, it’s as close as it gets. The Go Fast Bits atomic boost controller is compatible with over three dozen turbo models including the Eagle Talon, Subaru Impreza, Nissan Skyline, and Mitsubishi Lancer. Installation varies, depending on the location of the wastegate or boost source in some vehicles.
