How CarChip Works
The CarChip Pro plugs into the OBDII port in many 1996 or newer cars or trucks to record trip and
performance data. This data is then downloaded into your PC computer, providing a detailed look at how
the vehicle was driven, including trip start and end times, vehicle speeds, rates of acceleration and
braking, and also any OBDII trouble codes detected during the trip. The CarChip software displays vehicle
data in summary, plot or table format, and can also be exported to Microsoft Excel for further analysis.
The CarChip Pro also logs additional engine and vehicle data parameters, including an accident log which
records 20 seconds of vehicle speed history prior to every sudden stop.
