BimmerWorld View - Race cars in our world are built from street cars. If you leave the stock harness in the car, it's heavy and complex due to all the accessories you don't even have in the car anymore. If you strip the stock harness, you compromise its integrity, leading to potential electrical gremlins that make events and sometimes entire seasons painful. The SmartWire replaces the factory gear with a custom, intelligent solution. Worlds better than kits consisting of fuses and relays that require the driver to flip switches, watch gauges, and remember things. The SmartWire system has logic and is completely programmable so the driver can drive and the car's electrical system can function flawlessly in all conditions.

The Racepak SmartWire system is a fully programmable power control module that 
solves all the wiring complexity of the modern race car. While traditional wiring provides basic control of vehicle electronic components through the routing of wiring to single or multiple fuses, relay, and circuit breaker panels, the Racepak SmartWire functions as a complete central "command center" for all vehicle wiring. It not only cleans up the crazy mess of wires from a typical race car, it also gives a new level of control and peace of mind.

Based on Racepak's exclusive single-cable V-Net technology, the Racepak SmartWire module is the electronic hub, or starting point, with a direct main-power connection from the vehicle battery to the module. Each input and output can then be defined by the user for function, power requirements, and current-exceeding limits - programming is performed via a USB connection to a PC. The efficient design of the module reduces overall installation weight and clutter, and also provides a quicker-reacting electronic system thanks to the solid-state switching design.

An optional eight-switch Racepak SwitchPanel or 16-channel SwitchModule
 allows for manual activation and full use of the system. Clutter is reduced thanks to the small single cable routed to the SwitchPanel from the Racepak Smartwire unitFor users needing additional switch panel capabilities, the system can be easily expanded through the use of a jumper cable to a second Racepak SwitchPanel.

The V-Net compatibility ensures a seamless integration with existing Racepak data logger or display-equipped vehicles, while also providing a future upgrade path for additional inputs, control modules, and instrumentation when utilized as a standalone power-control module.

Each Racepak SmartWire Kit includes the module, software, connector kit, and USB programming cable.
