What is OBD-II anyway?
OBD II stands for On Board Diagnostic. An interface that can be used to control the engine, monitor different car parameters and read the “Check engine light” codes to determine possible problems. OBD-II can be found in most cars on the road today and it is a standard for all cars since 01/01/1996. OBD-II is the portal to communicate with the ECU – make sure you stay friendly.
What OBD-II can do for me?
To read the OBD data it is necessary to plug into the OBD-II port that can be reached from the driver’s seat.The info reading is done by an external device such as Laptop or Scangauge 2 that can extract and present interesting data such as: Speed, RPM, timing advance, MAF air flow rate, Throttle position, oxygen sensor reading, engine coolant temperature. This data is critical for effectively control hho system and our plan is to tap this info into our control box for precise control. For example throttle position will be used to control how much power will be activated on the hho cell. Meanwhile we use Scangauge 2 to verify that our car is working like it spouse to together with HHO. Moreover OBD-II helps us to know what's wrong when “Check engine light” appears (Very common when playing with oxygen sensor reading and air/fuel ratio :] ), I use this Fault codes reference guide to determine the problem, saves lot of time and money not to garage the car every time the red light shows itself.
The Revolution
Rev by DevToaster is the first iPhone application to connect with OBD-II interface.
Real Time Metrics include:
Vehicle Speed (including 0-60 time), RPM, Fuel Consumption, Engine Coolant, Temperature, Fuel Pressure and more.
Rev also reads and lists engine codes and allows you to reset them as well!
Rev communicates directly with your vehicle's ECU via an OBD-II hardware device. The hardware sends your data to Rev wirelessly.
