This plug-and-play unit offers selectable maps, which can be accessed through a smartphone application via Bluetooth. To access this app, you must download them from either the Apple App Store or the Google Play Store. The maps are specifically designed to optimize performance based on different octane fuel levels. You have the flexibility to choose between 91, 93, and 100 octane options. This Controller was developed with our Heat Exchanger (CBA08-00-8194), which dyno tested to drop the intake temperature by an astonishing 34 degrees Fahrenheit, installed to achieve the claimed power output. It is required for our matching factory warranty! Additionally, CarBahn offers an optional powertrain warranty for all their products, including the CPC. If you wish to switch from the CarBahn Performance Controller to software in the future, there is an upgrade fee of $250. However, if you have purchased a warranty, it can be transferred to the software upgrade at no additional charge!!
