Welcome to CarChip
CarChip consists of a tiny “black box” data logger (about the size of two 9-volt batteries stacked together), a CD
with software for analyzing the data, and a connecting cable and power adapter. The data logger plugs into the
OBDII connector in your car, and continuously collects and stores data from the car’s computer control systems.
Later, you use the cable and power adapter to download the information to your PC.
OBDII—shorthand for “second-generation on-board diagnostics”—refers to the complex set of computer control
systems found on every car sold today, model-year 1996 or later. Originally developed to help minimize
pollution, these systems are now used to improve fuel economy, measure overall engine performance, and help
identify specific component failures.
The data from these systems was once available only to professional mechanics. With CarChip, this same data
is now in your hands, giving you an insider’s peek at how your car is being driven, what’s going on inside the
engine, and more.
Additionally CarChip also records detailed trip information including the start and stop times for each trip, miles
traveled, plus accelection, braking, and speed data which is recorded in 5-second intervals.
Getting Started with CarChip
To help you get started with your new CarChip, we’ve provided some background information on how CarChip
works, the installation procedures (also on packaging), and an short overview of how to setup the software and
how to start using your CarChip.
How CarChip Works
The CarChip 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.
Note: See the CarChip Specifications for more information on vehicle compatibility
The more powerful CarChipE/X logs additional engine and vehicle data parameters, including an accident log
which records 20 seconds of vehicle speed history prior to every sudden stop.
Use CarChip for:
• Troubleshooting your car
Records trouble codes and freeze frame sensor readings
•
Logging your car’s performance
Records acceleration, deceleration, and speed.
• Recording trip information
Records dates, starts and stops, and distance.
• Clearing your car’s check engine light
Use CarChip E/X for:
• Engine performance data logging
Log 4 out of 23 available data parameters..
• Creating an Accident Log for every hard and extreme stop
What is OBDII
OBDII, or "on-board diagnostics two", is the on-board automotive diagnostics system that has been required by
the EPA on every new motor vehicle sold in the USA since 1996. OBDII is also found on many vehicles sold
internationally since 1996. The on-board diagnostics monitor virtually every component that can affect vehicle
emissions and many other vehicle functions and operations as well. Any detected problems will be recorded by
the system and will cause the vehicle's check engine light to be illuminated.
Note: See the CarChip Specifications for CarChip's compatibility with the five different OBDII protocols.
