  2. GRM car: NA car
  3. 4 window hall sensor
  4. target board v3.2
  5. Most copied from Marcell's v3.1 config and tables
  6. Im not sure which injectors I have
  7. going with lebaron 2.2 turbo injectors
  8. Injectors Populated: INJA, INJB, INJD, INJG
  9. Wideband Heater: WB1
  10. IGNition Drivers: DR_00, DR_01, DR_02, DR_03,

  13. Pump Priming
primep=0D # 1.3ms
  2. --- Hot start Priming pulse scaling at 170F (80= half FF = same as cold)
primep_temp_scaling=A0
  1. ======== Cranking Pulse
  2. typically cwh =~ 0.2 * cwl
cwl=46 # Cranking pulsewidth [100 usec] at -40 F (7ms)

cwh=14 # Cranking pulsewidth [100 usec] at 170 F (2ms)

cranking_thres=03 # Cranking threshold [100 rpm]

  2. Initial Start and Warmup
  4. ======== Afterstart
  5. TODO: try avew=28 and awec=A0 initially
awev=44 # Afterstart warmup enrichment (percent, added value)

awev_temp_scaling=98 # Afterstart warmup scaling at 170F (80=half, ff=same as cold)

awec=41 # Afterstart number of engine cycles

  1. ======== Warmup Coolant
  2. warmup_clt_range defines the temperature bins used for interpolation
  3. the values in warmup_clt_range is degrees Fahrenheit + 40
  4. C = 5/9 * F - 40
  5. F = 9/5 * C + 72
warmup_clt_range[0]=00 # -40.0 C

warmup_clt_range[1]=14 # -28.8 C

  2. Injector settings
  4. Fueling Parameters (Last years settings bad! Need NON-PWM settings)
req_fuel = 48 # Fuel constant (req_fuel) (72 Decimal)
  1. for a 4 cyl you normally want
  2. divider * (alternate+1) = 4
  3. That is divider=02 and alternate=01 for 2 banks
  4. or divider=01 and alternate=03 for 4 injector banks
divider = 02 # IRQ divide factor for pulse
  1. this is alternate=01, but bit4=1 enables squirting both banks at cranking
alternate= 11 # Alternate injector drivers Works with h[0]

# alternate = 00 means use only first (batch fire or TBI)

# alternate = 01 means alternate between first and second

# alternate = 03 to use indexes 3,2,1,0

# alternate = 07 to use indexes 7,6,5,4,3,2,1,0

injopen=22 # [16usec] based, (mutiply MS standard value by 6.25 to get [16usec])

battfac=24 # [16usec] based, (mutiply MS standard value by 6.25 to get [16usec])

  1. TODO: 104 kPa (GM) MAP sensor. Do you have this?
kpafac=34

injpwmt=FF # Injector PWM time at which to activate pwm [100 usec] FF=disabled (set to 1 mS per MegaManual for starting point)

tpsaq[0]=00

tpsaq[1]=00

  1. not sure about these
tps_thresh=05

tpsacold=05

tpsdq=64

decel_fuelcut_thres=FF

overrun_fuelcut=10 # 1600 RPM

  2. Rev limiter
  4. Rev limit (hard) [x100 rpm] eg. 0x4B * 100rpm = 7500rpm
rev_limit=4B
  2. No idea
airden_ignore=62
  2. these are important
  3. These useful descriptions are left over from Megasquirt

config11=30 # old config 31

config12=30 # 4 cylinders

config13=02 # old config 00

  2. battery calibration for starting and dwell I believe
batt_cal=BC
  2. Fast Idle
fastidle=C6 #RPM??
  2. Barometer settings
  4. ==== Mean Barometric Pressure -- TODO explain better
baro=64
  1. ========= max allowed difference in barometric pressure
  2. else use baro=0x64 (100 kPa)
  3. dbaro=10 # Marcells setting
dbaro=0C
  2. TPS calibration
  3. read TPS from LCD (or serial connection Manmll)
  4. in both endstates of throttle and configure these
  5. Important for triggering idle mode and acceleration enrichment
  6. --- TPS calibration means that the Analog(voltage) to Digital (count) is set
  7. at zero throttle and Wide Open Throttle (WOT)
  8. The standard: lowest voltage for closed throttle
  9. highest voltage for open throttle
  10. --- See Manual or wiki page for how to hook up.
  11. --- Most Tuning software has this function in them
  12. Megatune, Megatunix, etc.

tps_low=00

tps_high=FF

  2. Coolant Fan output
  3. This ouput is generally used to trigger a relay to turn on
  4. the electric radiator fan, or engage the electric clutch for
  5. engine cooling fan
  6. NOTE: the GRM cars use the stock VW low temp fan switch in the radiator
  7. And as such this ouput is not needed
  1. --- Temperature when fan will turn on degC eg. 0x55 = 85degC
fan_temp=EA
  1. --- Decrease in temperature required to turn fan off.
  2. --- fun_temp-fan_hyst=temp when fun will turn off 0x55 - 0x09 = 0x4C (76degC)
fan_hyst=05
  1. coolant fan, output selection (digitalout)

  2. Idle air controller -- I dont have one.
  4. This is where the idle is setup lots of stuff here to screw up.

  2. Dave Brul's EGO setup

  1. --- Max TPS position for ego correction, This setting allows for learning at WOT
ego_maxtps=FF
  1. --- Max MAP for O2 correction[kPa]

  3. Marcell's setup is special and MUST NOT BE USED
  4. TODO: Rip MCELLs WBO2 from the Reference firmware
  5. TODO: setup standard LSU4 setup and other std WBO2 used
  7. Dave Brul's WBO2 setup
  8. wbo2 config with softpwm_act; softpmw_act_var is broken!!

  1. Dave I see your calculations here. Are they for the Calibration?
  2. How about putting a worksheet here?
  3. (2.55mA * 61.9 / 106.2 ) + 2.55 = 4.036299 mA
  4. 4.036299 * 510 Ohm = 2.058512712 V
  5. i measured +/- 2.06V -> Good!
  6. 1% is eaten by the 10k pump+ to pump- resistor
  7. but does the AE calibration value also match my Rcal of 106.2 ?
  1. --- O2 percentage of 'normal' air: 20.947%, calibrated to 20.95

  6. engine with bore 83mm and stroke 86mm
  7. f_knock = 900 / (pi*r) = 900 / (pi * 0.5 * 0.083) = 6.903 kHz

  1. injector sequence
  2. maskconfig.alternate elements are used
  3. (going reverse order, last element is looked up first).
  4. FETs are numbered 01,02,04,08,10,20,40,80.
  6. Injectors Populated:
    1. INJA[01, EC36p07]
    1. INJB[02, EC36p19]
    1. INJD[08, EC36p20]
    1. INJG[40, EC36p06]
  7. LSB fired first
  8. this fires them in batch mode A&B and D&G
h[0]=03 48 00 00 00 00 00 <for fuelpump_channel=70 here goes injmask for fuelpump relay>
  1. NOT used Obsolete
h[1]=00 00 00 00 00 00 00 00
  1. Ingition Driver
  2. Fire the one installed
  3. IGNition Drivers Installed
  4. DR_00[h[2] = 00, EC36p35]
  5. DR_01[h[2] = 01, EC36p33]
  6. DR_02[h[2] = 02, EC36p34]
  7. DR_03[h[2] = 03, EC36p36]
  8. using DR_03 just to show where it goes, not that it has to be this one
h[2]=03 03 03 03 03 03 03 03
  1. wasted spark would look like
  2. h[2]=01 02 01 02 01 02 01 02
  3. chris G's notes:
  4. third line contains the ignition sequence, each element
  5. represents the bitnumber of the p259 output going to coil
  6. we start at the end (ignchmax) and work our way back
  7. fire igbts 07 for all events please (single coil firing through distributor)
  1. these are for something else
b[0]=28 30 38 40 48 50 58 60
