Code Scanner, Data Logger, and Real-Time Engine Data Display

This innovative system is a code scanner, data logger, and real-time engine data display (with a USB connection) for GM OBDI cars and light trucks (1995 and older). The ATmega169-based system was tested on a 1994 Chevy Caprice to help diagnose engine problems.
