CarChip fits most 1996 and later vehicles sold in the USA as well as many vehicles sold outside the USA (see below), to automatically record and store 75 hours of trip details, including: Time, date and distance for each trip Speed logged every 5 seconds Hard acceleration and decelerations Engine diagnostic trouble codes and status of other engine parameters when the code occurred Idle time Time and date CarChip is connected or disconnected. In addition to the above features, the advanced model, CarChip E/X stores 300 hours of trip details and measures up to four engine parameters every 5 to 60 seconds (and there are 23 parameters to choose from!). CarChip fits most 1996 and later vehicles sold in the USA, and therefore many vehicles sold outside the USA. Outside the USA you must check on which cars CarChip will work. Even when there is an OBD adapter in the vehicle, it does not always mean that the CarChip will record data because of non-standardized protocols. The practical rule is that the CarChip will work with vehicles that use one of the following four protocols: J1850 VPW J1850 PWM ISO 9141 KWP2000 (ISO 14320) The CAN protocol (ISO 11898) is not supported by the CarChip.
