The leftovers:
This photo didn't come out very well, however I couldn't help but notice the file name...

As listed in the above post, the sections are:
- Power Supply
- RS232 Comms
- Clock for MS1
- Square Wave Input
- VR Input
- Analog Inputs
- Map Sensor
- Fast Idle
- Fuel Pump Drive
- Ignition Output
- Injector Outputs
- LED Outputs
And the components for each are:
Power Supply
Will fill this out after dinner.
- Varistor (MOV): 1
- Capacitors (C): 15,16,17,18,19,22,23
- Diodes (D): 9,10,11,12,13,19
- Inductors (L): 1,2
- Poly Fuses (F): 1,2
- 5V Regulator (U): 5
RS232 Comms
Installed, but will not be used in the medium term.
- RS232 Driver (U): 6
- Capacitors (C): 26,27,28,29
Clock for MS1
Not required for MS2, C1 and R1 are not for the clock, but also not required.
- Resistors (R): 1,21,22,23
- Capacitors (C): 1,20,21,24,25
- Crystal (Y): 1
Square Wave Input
This section has some optional components for different specific uses and installation conditions.
We installed these components for a clean optical CAS output:
- Resistors (R): 12,13
- Opto Isolator (U): 3
- Capacitor (C): 11
And did not install these ones:
- Diodes (D): 1,2
- Capacitors (C): 12,30
VR Input
Doesn't work properly, extremely difficult to adjust, unused on vehicle with optical CAS. Should have been an IC from the start, such as LM1815.
- Resistors (R): 42,44,45,46,47,48,49,50,51,52,53,54,55,56
- Diode (D): 24
- OpAmp (U): 7
- Transistors (Q): 22,23
- Capacitors (C): 31,32
Analog Inputs
Will fill this out after dinner.
Includes MAP sensor filter components, reused for external MAP.
- Capacitors (C): 2,4,5,6,7,8,9,10
- Resistors (R): 2,3,4,5,6,7,8,9,10,11
Map Sensor
We're using an external 3 bar map sensor. For safety we'll add a normal diode to divert > 5V signals to the 5V rail. See above for the other two related components that are still used.
- MAP Sensor (U): 2
- Capacitor (C): 3
Fast Idle
Too weak for any sort of PWM usage etc.
- Resistors (R): 19,39
- Transistors (Q): 4,20
- Zener Diode (D): 8
Fuel Pump Drive
- Resistors (R): 16,40
- Transistors (Q): 2,19
- Zener Diode (D): 4
Ignition Output
This does not belong inside the box, just ask almost any OEM.
- IGBT (Q): 16
- Resistors (R): 43,57
Injector Outputs
Massive overkill for high Z use, and low Z does not belong inside the case either. Additionally, not enough to properly control any normal 4, 6, or 8 cylinder engine with sequential injection which is essential with HUGE injectors such as Dan's BF/B6. We are running Jean's P&H driver board in an external case.
- Diodes (D): 3,5,6,7,17,18,20,21
- Transistors (Q): 1,3,5,9,10,11,12,13,14,15
- Resistors (R): 14,15,17,18,20,30,31,32,33,34,35,36,37,38
- Capacitors (C): 13,14
- FET Driver (U): 4
LED Outputs
For our purposes, these will be rewired to connect to the fuel outputs and use green LEDs, there will be a fourth one installed, too. Two additional red LEDs will be installed on the underside of the board with matching driver circuits and will indicate the ignition channels.
- Resistors (R): 24,25,26,27,28,29
- LED Diodes (D): 14,15,16
- Transistors (Q): 6,7,8
I hope this helps someone else in future. At the least it is a good reference for us and this particular unit.
