Sub-page for MembersPage/SteenAndersen
This page is intended to describe my specific installation of GenBoard.
I'm using the tach signal for trigger, it's set for 6 cyl, and DummyIgnition on IGN_03. I used a 470nF capacitor to tap the tachometer signal directly from the tachometer, and i unsoldered R30 on the GenBoard.
The installation is not set to control the engine yet (have no electrical control to motor yet). I have only hoked vems up as a meassuring device for now. I have connected the CLT to the original Bosch oil temperature sensor, and temperatures seems right with readings from 2°C celsius on a cold morning's to 95-100 °C celsius with warm running engine. I also have MAP connected, and i made a sensor for CHT (cylinder head temperature) from a NTC resistor from the WebShop, but reading is suspicious, i get almost same cold redings as CLT, but warm engine tempratures is in the 60-70 dec. celcius, where i suspected higher temoperatures than the oil temperatures measured by CLT.
This config and tables are not completed, not all parameters are set, and in tables only h[] are configured yet.
Here's teh commented version of config .txt and tables.txt

# Fueling Parameters
# DONE: Req_fuel recalculated.
#
# COMMENT:
# For Req_fuel information
# see: http://www.megasquirt.info/manual/mfuel.htm#reqfuel
# see: new wiki page
# Scaling the VE and and req_fuel effectively increases the resolution
# of the fueling parameters.
# EXAMPLE:
# scaling is accomplished by making:
# req_fuel = calculated req_value / 2
# VE_TABLE==> j[] = j[] .*2 (matlab notation)
# This changes the range of values in the j[] table
# from 1..100 to 2..200
#############################################################
# ===== Req_fuel Setup ==============
# req fuel for 911SC is calculated to be >>10.6ms<< via mega manual
# 181 cui displacement , 6cyln, 6 injectors, 1 squirts, 30lb/hr, staging:none
# req_fuel variable is in hex and is multiplied
# 0x00 * .1ms EXAMPLE: 3.2ms = 0x20
# 10.6ms ==> 0x6A
#
# Normal Req_fuel setting ( j[] table 0..100*256 )
# req_fuel = 6A # Fuel constant (req_fuel) (10.6ms Decimal)
#
# injectors ?unknown? 305 cc/min @ 3bar (30lb/h)
# engine 3000 cc
# Normally: req_fuel=6A
# (To double the VE table resolution divide req_fuel by two Thus req_fuel = 0x6A div 2 = 0x35)

# ===== Divider ============================
# COMMENT: Better notes here required
# For a 4clyn you want divider * (alternate + 1) = 4
# divider * (alternate+1) should be 4 for a 4 cyl
# divider=02 and alternate=01 for 2 banks
# divider=01 and alternate=03 for 4 injector banks
divider=01
# ===== Alternate Injector bank setup ======
# 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 = 05 to use indexes 5,4,3,2,1,0
# alternate = 07 to use indexes 7,6,5,4,3,2,1,0
#
# add 0x10 (bit4=1) to fire all at cranking
# (all 6 in this case) simultaneously at cranking
# so this is alternate=05 for 6cyl, but bit4=1 enables squirting both banks at cranking
# Bitwise 0x0001 0101

# ======== High Z INJECTORS =============== MAY USE ONLY HIGHZ or LOWZ settings
# For non-PWM settings INJPWMT=FF, INJPWM=FF, INJPWM6=00 sets up HIGH Z injection
# COMMENT why wouldnt INJPWMT be set to 00, then it doesnt need to get "disabled"
#
#injpwmt=FF # Injector PWM time at which to activate pwm [100 usec]
# FF=disabled (set to 1 mS per MegaManual for starting point)
#injpwm=FF # Injector PWM duty cycle (when current limiting is active)
# (set to ~100% [FF] no PWM - JJR 03/31 15:15)
#injpwm6=00 # added Injector PWM duty cycle during low battery voltage (6V)
# ======== Low Z INJECTORS & PWM variables ===============
# The advantage of using LOW Z injectors is faster opening and closing times,
# based on the simple physics of more current to open the injector and less stored energy
# when closing the injectors
# Low Z injectors are designed to work on a Peak and Hold manner
# During the Peak stage the current is switched on allowing the maximum
# current to flow to open the injector in a fast manner. This takes place
# at the beginning of each injection event (squirt) for a specific period of time
# This entered into INJPWMT ( injector PWM start timedelay )
# -- Not configured yet --
injpwmt=0A # Injector PWM time at which to activate pwm [100 usec]
# FF=disabled (set to 1 mS per MegaManual for starting point)
# Then the injector starts the hold mode where the PWM % becomes applicable.
# to hold an injector (solenoid) open takes significantly less power
# the injector no longer has to charge or overcome the fuel pressure to keep it open.
# the current during the hold cycle is calculated by
# I = V/R * % duty cycle
# verify by measuring OC0 with DVM
# [0.4%] unit, so FF is 100% (that measures OC0=0V; since this is before the inverting FETdriver)
# 48/256 (=3/16), that measures OC0=5V * (256-48)/256
# -- Not configured yet --
injpwm=30 # Injector PWM duty cycle (when current limiting is active)
# In the case of low battery to keep the same I(current) the duty cycle must be increased.
# COMMENT: this is straight forward and should be built into the firmware
# 6volts = Vbatt/2; Iold = Inew; dutycycle should be equal to 2x 12volt percentage.
# -- Not configured yet --
injpwm6=40 # added Injector PWM duty cycle during low battery voltage (6V)
# Constant to calculate RPM:
# 12000 rpm/4clyn = 3000=11*256 + (11*16 +8) =0x0BB8
# 12000 rpm/6clyn = 2000=07*256 + (13*16 +0) =0x07D0

# ===== TPS calibration =================
# read TPS from LCD (or serial connection Manmll)
# in both endstates of throttle and configure these

# --- TPS calibration means that the Analog(voltage) to Digital (count) is set
# at zero throttle and Wide Open Throttle (WOT)

- take your earlier commented etc/config.txt (or a commented similar config)
- save partial or full actual config values as etc/mcd.txt (no need for comments here). Values in this file will take precedence over config.txt
- run make mtt (it runs perl bin/make_conf.pl, running manually or makemtt.bat file is OK)
- examine output if you like the updates
- the config.mtt can be uploaded to controller
- update the comments in config_mcd.txt if necessary (the values that changed due to mcd.txt might need comment changes) and rename it to config.txt when you like it.
