iPhone talks to the car’s OBD port using Wi-Fi

DevToaster has released REV2.0, an application with an OBD kit that can transfer diagnostic information from the car to the iPhone using Wi-Fi.

Rev gives access to lots of vehicle metrics, communicating via an OBD-II device to extract highly accurate, real-time data directly from the vehicle’s ECU. These metrics include:

  • Vehicle Speed
  • RPM
  • Fuel Consumption
  • Engine Coolant Temp
  • Fuel Pressure
  • Calculated Engine Load
  • Throttle Position
  • Intake Manifold Pressure
  • Air Intake Temp
  • Timing Advance
  • Mass Air Flow
  • Fuel Level
  • Barometric Pressure
  • EVAP System Vapor Pressure
  • Fuel Trim

The iPhone app costs $40 and the OBD-II connector costs $150, but the company is working to reduce this cost.

Note: Currently, this product is marketed as a racing car app for drivers to understand and improve the engine’s performance. However in the future, similar applications on Smartphones can be used to provide eco-driving tips, remote diagnostics and much more.
