background
The CSULA ECOCAR 2 is a parallel-through-the-road hybrid vehicle converted from a 2013 Chevy Malibu.
The Computer Science Team replaced the center stack system of the hybrid vehicle.
In addition to maintaining original functionality, the team added a diagnostic display. *

Advice for Future Developers
The CS team learned firsthand about the difficulties of integrating software with hardware
> Test on actual car as soon as possible to expose communication problems early
> Make some individual responsible for successful integration of hardware and software
> Learn the limitations of running on a board vs. a standard computer
