Exclusive OBDKey Features

Extended command set so that OBDKey can perform enhanced diagnostics not possible with simple ELM based scan tools. However, OBDKey is compatible with the legacy ELM327 command set which means you can also run ELM based applications with the OBDKey device range.
Upgradeable firmware. Updates available to add new features to the already stable and well proven OBDKey core firmware. Keeping your OBDKey adapter up to date and protecting your investment.
Battery saving technology which prevents the OBDKey from keeping the vehicle ECU systems awake for longer than is really needed. Regular battery checks should be carried out if you leave any device permanently connected to your vehicle.
Super advanced multi-protocol auto-detect processes. Further custom protocol support also available. OBDKey connects to more OBD-II and pre-OBDII vehicles than any other scan tool adapter on the market in this class.
Stable connection to all supported vehicles
Large and reliable enhanced protocol memory buffer. Faultless and error free data acquisition guaranteed from OBDKey

The OBDKey WLAN is capable of working in ad-hoc and infrastructure (via an access point) modes.  In ad-hoc mode the OBDKey WLAN will create a wireless LAN network with a new SSID for other devices to detect and connect to.
