  6. COMMENT:
  7. For Req_fuel information
  8. see: http://www.megasquirt.info/manual/mfuel.htm#reqfuel
  9. Scaling the VE and and req_fuel effectively increases the resolution
  10. of the fueling parameters.
  11. EXAMPLE:
  12. scaling is accomplished by making:
  13. req_fuel = calculated req_value / 2
  14. VE_TABLE==> j[] = j[] .*2 (matlab notation)
  15. This changes the range of values in the j[] table
  16. from 1..100 to 2..200

  17. alternate=03
  18. divider=01
  19. h[0]=02 08 04 01 00 00 00 00
  21. add 0x10 to fire in 1-batch mode at cranking

  2. for more detailed information look:
  3. MembersPage/MarcellGal/EngineSwap/Feed
  4. http://www.vems.hu/wiki/index.php?page=MembersPage%2FMarcellGal%2FEngineSwap%2FFuelFeed
  5. http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FConfig%2FInjectorOpening
  6. [ This comes from I = V/R, the current flowing varies with the voltage applied since
  7. the resistance of the injectors remains constant ]
  9. injopen should not be set higher than 0x20 (512us);
  10. If injopen is too high, VE table at low kPa (j[0]) will have very small, untunable values
  11. There is a bad rumour that injopen is the time needed for the injector to open.
  12. It is not the case, and it has never been the case.
  13. The misconception comes from the fact that if an injector opens slower
  14. than another injector with all other parameters the same,
  15. injopen value will be higher. Even with simpler injector opening models,
  16. injector closing is also heavily involved.
  17. In very short and simplified form: injopen=injector_opening_time - injector_closing_time.
  18. But read more:
  19. http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FConfig%2FInjectorOpening

injrampup_battfac=FF
  2. High Z INJECTORS
  4. For non-PWM settings INJPWMT=FF, INJPWM=FF, INJPWM6=00 sets up HIGH Z injection

  13. verify by measuring OC0 with DVM
  14. 0x01=0.4%
  15. eg 0xFF=100% (that measures OC0=0V; since this is before the inverting FET driver)
  16. 48/256 (=3/16), that measures OC0=5V * (256-48)/256
  17. Injector PWM duty cycle (when current limiting is active)
  18. injpwm=30
  20. In the case of low battery to keep the same I(current); the duty cycle must be increased.
  21. COMMENT: this is straight forward and should be built into the firmware
  22. Also, shouldn't this be taken care of by battfac? Seems redundant.
  23. 6volts = Vbatt/2; Iold = Inew; dutycycle should be equal to 2x 12volt percentage.
  24. added Injector PWM duty cycle during low battery voltage (6V)
  25. injpwm6=40
