This project was begun as a response to build simple ISO9141-2/14230-4 ELM323 compatible USB adapter for On Board Diagnostic (OBD2) monitoring.

If you are thinking to move on DSP, maybe dsPIC microcontrollers can be a good start as they have DSP engine built in that allows fast multiply and divide operations with arrays.
