Was intending to buy one to see what they are like. Ive bought a few Gps trackers and most have been good. If these can relay vehicle data in real-time, that would be cool. OBD2 port doesn't switch off with ignition so just be careful you don't drain your battery! Yeah....says 22mA current draw on 12v......but the bike is on an optimate in the garage when it's not being used, Joe. I think it just gets its power from the OBD2 port.....so, no real time data from the ECU.......although there is an OBD2 bluetooth transmitter available for that......
