Any 'gearheads' out there? FreeScale based engine controller. in Other Microcontrollers Posted June 27, 2013 I started an EFI project as my senior design project a year ago. We got caught up in numerous other things and never really got started on the EFI part except from a conceptual standpoint, but had a lot of fun anyway. Our base was the Parallax Propeller combined with MSP430. The horsepower from the Prop allowed us to actually auto-generate the fuel map. The MSP430 was (going to be) used to read all analog signals and transmit back to the Prop.
