ELM327 Bluetooth with PIC18F25K80 chip is able to detect and interpret obd2 / eobd protocols automatically. It also provides support for high speed communications and a low power sleep mode. It use AT commands to communicate with a host device. There are plenty of software packages available, which are fully compatible with this tool. Some of them have pretty useful features, such as engine running parameters monitoring, DTC reading and clearing, MPG meter, etc. You can even write your own software on a specified hardware platform if you wish, because the AT commands are fully documented and very well explained. It is compatible with 2001 and later vehicles which are obd2 or eobd compliant.
With proper software installed in the host device, you may have following parameters read out from your vehicle:
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
Note:
Your vehicle may not support all above parameters.How many parameters you can get is depended on the vehicle manufacturer’s implementation.
