Ever had that darn annoying little "check engine" light come on your dashboard? It costs a ridiculous 75 bucks just to "hook up your car and see what the computer says." And that doesn't include the cost to fix it, if anything really is wrong.
There's a very cool little thing-a-ma-jiggy called the CarChip E/X that lets you do this yourself.
Since 1996, thanks to emission control regulations, just about every car sold in the USA adheres to a protocol called an OBDII. This includes an interior plug which allows anyone with a computer hookup or data scanner (like the CarChip) to plug into the car's computer and download information.
With the CarChip E/X plugged into your car, it records up to 300 hours of your driving data. In other words the CarChip acts like a car blackbox. Every trip you make is recorded. The information it records includes: time and date for each trip, distance, speed, hard accelerations and braking, and engine diagnostic trouble codes. In addition, you can pick four other parameters to record ranging from RPM, engine coolant temperature, throttle position, fuel pressure, battery voltage, etc. Using the included software, you can then graph out the data to show you how your vehicle is performing. And like an airplane blackbox, if you happen to have the misfortune of getting into an accident, the CarChip E/X will automatically generate an accident log showing the last critical 20 seconds of speed.
