This thing appears to be a data logger that plugs into your OBDII (if you have one) that lets you record and analyze whatever is going on in your car from whatever parameters you can capture from the computer. Would be easier maybe than fooling around with a GPS, and give you more info too. $160
Just don't let BigBro (or your kids) know you have it. --R http://www.kk.org/cooltools/archives/000999.php 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. _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
