CAN)ISO 14230(aka. KWP2000)ISO 15765(aka. CAN)SAE J1939 CLKis able to detect and interpret these 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 (PC， notebook， iPhone， iPod touch， iPad and so on). There are plenty of software packages available， which are fully compatible withCLK. 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.CLKis measuring only 2.7 x 1.25x 0.9 inches， and it comes attached with a 6 ft OBDII cable for easy installation. It also comes included with a power switch built-in to prevent the need for having to constantly disconnect your unit from the OBDII port.It is compatible with 1996 and later vehicles. Connecting to your iPhone / iPod touch is made by WIFI connection in adHoc mode.With proper software installed in the host device， you may have following parameters read out from your vehicle:Vehicle SpeedRPMFuel Consumption*Engine Coolant TempFuel PressureCalculated Engine LoadThrottle Position
