  4. COMMENT:
  5. For Req_fuel information
  6. see: http://www.megasquirt.info/manual/mfuel.htm#reqfuel
  7. see: new wiki page
  8. Scaling the VE and and req_fuel effectively increases the resolution
  9. of the fueling parameters.
  10. EXAMPLE:
  11. scaling is accomplished by making:
  12. req_fuel = calculated req_value / 2
  13. VE_TABLE==> j[] = j[] .*2 (matlab notation)
  14. This changes the range of values in the j[] table
  15. from 1..100 to 2..200
  1. Req_fuel Setup
  2. req fuel is calculated to be X.Xms via mega manual
  3. 109 cid , 4 cylinder, 4 injectors, 2 squirts, 20lb/hr, alternating
  5. To double the VE table resolution divide req_fuel by two
  6. and multiply the values in the VE table by two
req_fuel=6E
  1. Injector firing sequence: alternating, X squirts per 720degree rotation
  2. COMMENT: Verify: The divider says how many times banks fire during
  3. 720degree rotation
  5. Injector bank setup
  6. Alternate injector drivers works with h[0]
  7. alternate=00 means use only first (batch fire; all injectors in one batch)

  2. For a 4 cylinder you want [divider * (alternate + 1)] = 4
  3. divider=02 and alternate=01 for 2 banks
  4. divider=01 and alternate=03 for 4 injector banks
divider=02

  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. BATTFAC is the extra time it would take to open if only 6V would be present (low battery)
  7. BATTFAC is also the decrease in time it would take to open if the applied voltage was 12V+6V
  8. [ This comes from I = V/R, the current flowing varies with the voltage applied since
  9. the resistance of the injectors remains constant ]
  11. Other things that can effect opening and closing speeds:
  12. The type of flyback chosen (high or low voltage)
  13. The type of injector used (high or low Z )
  14. The pressure differential (required force to overcome solenoid)
  16. MCELL suggests that INJOPEN not be set much higher than 512us = 32*16usec (0x20)
  17. shows up in low kPa setting being lower than high KPa settings in VE table (j[])
  1. injopen:
  2. Time required to open injector nozzle
  3. Elapsed time t=0 to begin fuel spray
  4. 0x01=0.16ms

  1. battfac:
  2. Injection time scaling based on supply voltage

  1. injocfuel:
  2. Maximum rampup time at VBATT=7V
  3. TIME IT TAKES TO REACH FULL FUEL FLOW THROUGH INJECTOR
  4. WHEN BATTERY VOLTAGE IS LOW?
  5. 0x01=0.24ms
injocfuel=08
  1. injrampup_battfac:
  2. Minimum rampup time
  3. MINIMUM TIME IT TAKES TO REACH FULL FUEL FLOW THROUGH INJECTOR
  4. WHY ARE WE CONCERNED WITH MINIMUM TIME?
  5. "min rampup time is injocfuel*77%"
  6. ^ DOES THIS MEAN injrampup_battfac MUST BE GREATER THAN 77% of injocfuel?
injrampup_battfac=FF
  1. High Z INJECTORS
  2. For non-PWM settings INJPWMT=FF, INJPWM=FF, INJPWM6=00 sets up HIGH Z injection
  3. COMMENT why wouldnt INJPWMT be set to 00, then it doesnt need to get "disabled"
  5. delta t=(t=0 to time initial resistance is overcome in injector)
  6. Injector PWM time at which to activate pwm
  7. FF=disabled (set to 1 mS per MegaManual for starting point)

injpwmt=FF
  1. Injector PWM duty cycle
  2. Measured in percent (50%=0x80, 100%=0xFF)
  3. 100% when using HighZ
injpwm=FF
  1. Added Injector PWM duty cycle during low battery voltage (6V)
  2. Measured in percent (50%=0x80, 100%=0xFF)
  3. 0% when using HighZ (we're already always at 100%)
injpwm6=00
  1. Low Z INJECTORS
  2. The advantage of using LOW Z injectors is faster opening and closing times,
  3. based on the simple physics of more current to open the injector and less stored energy
  4. when closing the injectors
  5. Low Z injectors are designed to work on a Peak and Hold manner
  6. During the Peak stage the current is switched on allowing the maximum
  7. current to flow to open the injector in a fast manner. This takes place
  8. at the beginning of each injection event (squirt) for a specific period of time
  9. This entered into INJPWMT ( injector PWM start timedelay )
  1. delta t=(t=0 to time initial resistance is overcome in injector)
  2. Injector PWM time at which to activate pwm
  3. FF=disabled (set to 1 mS for starting point)
  4. ISN'T THIS THE SAME AS injopen???
  5. 0x01=0.1ms
  6. injpwmt=0A
  1. Current during the hold cycle is calculated by
  2. I = V/R * % duty cycle
  3. verify by measuring OC0 with DVM
  4. 0x01=0.4%
  5. eg 0xFF=100% (that measures OC0=0V; since this is before the inverting FET driver)
  6. 48/256 (=3/16), that measures OC0=5V * (256-48)/256
  7. Injector PWM duty cycle (when current limiting is active)
  8. injpwm=30
  1. In the case of low battery to keep the same I(current) the duty cycle must be increased.
  2. COMMENT: this is straight forward and should be built into the firmware
  3. Also, shouldn't this be taken care of by battfac? Seems redundant.
  4. 6volts = Vbatt/2; Iold = Inew; dutycycle should be equal to 2x 12volt percentage.
  5. added Injector PWM duty cycle during low battery voltage (6V)
  6. injpwm6=40
  2. RPM Calculation
  4. eg 0x0BB8 = 3000 = 12000 rpm/4 cyl
  5. 4 cylinder: rpmk[0]=0B, rpmk[1]=B8
  6. 5 cylinder: rpmk[0]=09, rpmk[1]=60
  7. 6 cylinder: rpmk[0]=07, rpmk[1]=D0
  8. 8 cylinder: rpmk[0]=05, rpmk[1]=DC
rpmk[0]=0B

rpmk[1]=B8

  2. TPS related information
  4. TPS calibration
  5. read TPS from LCD (or serial connection Manmll)

  6. awev is the percentage added at startup that fades away
  7. to 0 in awc engine cycles.
  1. DEFINE ENGINE CYCLES
  2. 360 DEGREE CRANK ROTATION = 2 CYCLES?
  3. WHY DO WE USE ENGINE CYCLES IF WE ALREADY USE ENGINE TEMP?
  1. 15..40% (0F .. 28 hexa) are common (and sometimes even higher).
  2. Since originally warmup enrichment is not tuned, we often
  3. adjust awev (besides cwl,cwh) to start the engine, but after
  4. warmup enrichments tuning is done, awev must retuned
  5. to get back the desired pulsewidth. Take notes of
  6. working cwl,cwh, awev settings and actual CLT and
  7. the warmup enrichments, so when warmup values are changed
  8. awev can be changed with simple calculation instead of guessing

  2. VE learning VERY important
  4. COMMENT: Insert comments on enabling/disable/howto use
  5. Some basic comments:
  6. VE Learning can adjust a loadsite that is visited
  7. but not a neighboring loadsite that is rarely visited causing
  8. peaks and valleys in the VE (j[]) map that will need smoothed
  10. EGO correction is transferred across loadsites for fast loadsite-changes
  11. (that happens, especially in kPa direction)
  1. VE Learning Enable/Disable
  2. ve_learn_conf=01 / 00 is ON / OFF

  1. these are for something else
  2. WHAT MIGHT THAT BE?
