Soldering steps reminder list.
Before mintest
- big black barrell inductivity (1.5uH 5.4A or blue 3.3uH 8.8A)
- quartz 16MHz
- main fuse wire
- 0 Ohm resistor on the bottom (D45 for stepper?)
-
R154 under the atmega(factory populated since v3.3) -
LCD supply capacitor (C89) 10uF(factory populated since v3.3) -
Big Vbatt capacitor (C72) 10uF (min.25V) 1210(factory populated since v3.3) - Big 18V 1.5kE18 troughole transient suppression diode (bottom of the board) (factory populated SMB on top since v3.3, needs checking ! )
-
connect the GND bridge(not applied since v3.3) - pinheaders for the ISP
- do the firmware things and checks (bin/mintest.sh, bin/prog.pl)
Mintest possible at this point
- ...
- supply voltages
- supply current
- LCD test requires special connector (since no header) or a bit of experience
Optional stuff below
-
5V1 protecting zener for trigger1 D14(factory populated since v3.3) -
5V1 protecting zener for trigger1 D27(factory populated since v3.3) - configure trigger1 to VR (2 jumpers)
- configure trigger2 to HALL (1 jumper)
- trigger1 pullup resistor REMOVE (R55)
- EC connectors
-
flyback diodes(factory populated since v3.3) - flyback airwire (EC36 pin23)
- FETs
- IGBT
- additional brown GND5 airwire on bottom (EC36pin21,pin22)
- additional brown GND5 airwire on top (EC36 pin5)
- flyback testing: all inj. outputs toward the flyback rail
airwires to EC18
- knock
- RS232
- MAP signal (if not onboard MAP)
- hotmelt
Stepper
- stepper chip
- stepper capacitor (C75) 1210 (min.25V), 10uF
- stepper Vbatt wire in the place of D45
knock
- 4 MHz
- TPIC8101DW knock chip
for LCD that likes -3V contrast
-
R112=2k4(factory populated since v3.3) -
take out the 1k towards GND(not populated in factory since v3.3)
Final tests
- many
- pump- voltage
- wbo2_pump_pw_zero
- wbo2_nernstdc_target (0.45V between nernst and pump- when WBO2 activated with mde02 or RPM signal)
- 64-1 stim-out signal (mstbemsp03) from stepperA (0x36) output, and checking proper operation of all 8 injector and ignition channels with connected LEDs. Requires wasted-spark 16 cyl config with 64-1 wheel
A special board is used to test the outputs:
With a
- 64-1 stim-signal: mst7e msp02
- tooth_wheel=3e
- trigger_tooth=00
- another_trigger_tooth=08
- Note: "coil-type" input-trigger works as well, than the above wheel-parameters are not used, and mst3f msp24 command is used to drive the OutputTrigger
- alternate=07
- h[0]=01 02 04 08 10 20 40 80
- ignchmax=07
- h[2]=00 01 02 03 04 05 06 07
it's obvious from first glance if there is any irregularity due to:
- firmware problem
- HW problem (eg. 2 neighboring IGBT-s shorting because of clamping problem)
- config problem (eg. bad trigger configuration or fuelcut)
Note that this does not substitute the flyback test.
The same board can be used for different tasks, for example:
- upper (outer 4 + inner 4=total 8) RED as shiftlight
- the other 8 (non-RED, eg. green, blue, yellow and white) LEDs for different status indication:
- fuel-pump active
- variable-intake actuator active
- boost-solenoid active (makes boost-PID tuning easier)
- warmup enrichment active (the output channel for this is not currently configurable)
- finally integral-rail in various PID controllers (idle, boost, WBO2 pump, WBO2 heater, etc...) Note that these indications (although not too complex) are not implemented yet.
- CEL (check engine light)
- add your wish here
- etc...
