Digital fuel injection test
-Throttle body & injector from Yamaha YBR125
-Fuel Pressure regulator from Nissan Skyline GTR
-Fuel Pump and Filter from Triumph Speed Triple
-Microcontroller is Atmega328p with Arduino bootloader
- Fllywheel vr sensor triggers on-chip comparator, flagging interrupt, which starts injection, loads output compare register, as well as triggering Input Capture for RPM measurement
- 16bit Timer with /64 prescaler = 0.0004 second accuracy. Output compare triggers interrupt to stop injection
- Fuelling algorithm is Alpha-N : TPS vs RPM in a 16x16 2-byte EEPROM array
- UART Serial communication allows on-the-fly editing of EEPROM, as well as diagnostic output.
