WifiLapper is a free and Open Source Android Application that transforms your phone into a full featured Racing Data Acquisition system. WifLapper can transmit your lap times and sensor data from your car to a laptop running Pitside using Wifi or Cellular Data Network while the car is still racing.
Sensors data can come from either your car's built-in OBDII interface using a simple Bluetooth adapter, or through an external IOIO interface. Up to 16 Analog inputs and multiple digital inputs are supported by IOIO, allowing WifiLapper to record any sensor that outputs a voltage.
