PIC based Motorcycle Injector Control

by J.A. Wisman [J.A.Wisrnan a+ phys.uu.nl]

for the Olimex sponsored PCB contest

Opens the motorbike's injector for a period of time that it looks up from a table in an EEPROM (SPI interface) indexed by the engines speed and throttle position.

For adjusting the system, the system sends the measured value's to the PC.  The values sent are: The number of revs, throttle position and the matching Injector time.

You can also send new value's to the system: i.e. number revs, throttle position and injector value.

It works on the workbench but we have not tested it in "real life"

• Schematic PDF PNG
• Gerbers ZIP Board layout files from Mentor Graphics
• Source Code ZIP Written in  HiTech C
• INJECTIE.HEX PIC Hex file.
• PC Software ZIP 30MB PC application to read and set the injector system variables.

And here is the finished board up and running! Thanks to Jody for the picture.
