CarChip • MSRP: $99
CarChip has a datalogger the size of a 9v battery that plugs into the OBD port on any ‘96-or-later vehicle. It can record up to 300 hours of continuous driving data for review and analysis. The data can be read on a PC and looks at up to 23 different engine parameters. In some applications it can also reset a check engine light and tell you why it illuminated in the first place. While it’s endorsed by Impact Teen Drivers as a safety device, we can think of more uses than simply monitoring your offspring. The CarChip Data Logger comes with a USB cable and desktop PC software to get you started.
