Engine Swap

[Build] [Mechanics] [Electrics] [Megasquirt]

The connectors and pin layouts:

Engine speed sensor
(Bosch 0 261 210 148)

(the closest I could find!)
Datasheet
Drawing
 

1. GND/shield
2. IGN (pin 24)
3. IGN GND (pin 7)

Coolant sensor
(ELTH 078 919 501 B)

R(0) = 5940 Ohm
R(22) = 2300 Ohm
R(100) = 200 Ohm

1. signal (pin 21)
3. GND

Throttle Valve control unit
(without cruise control)
(06A 133 063 G)

1. actuator +12V/3A (idle control)
2. actuator GND (idle control)
3. throttle closed = pin 7 / open = ∞
4. GND
5. TPS (0,6V closed / 4,3V full)
6. Not connected
7. +5V
8. Not needed (TPS with smaller range)

Intake Air Temperature
(Bosch 0 280 130 085)
(VW/Audi 058 905 379)

R(0) = 5200 Ohm
R(22) = 2200 Ohm 
R(100) = 200 Ohm 

1. IAT (pin 20)
2. GND

Ignition Coils
(Hitachi CM11-201)
(BERU ZSE 009)
(VW/Audi 06B 905 115)

1. +12V
2. signal GND
3. +5V trigger signal
4. coil GND

dwell = 2.4 ms (12V)

 

Used spark plugs: NGK BKR7E

Knock sensor (2x)
(VW/Audi 06A 905 377 A)

1. signal
2. reference ground
3. screening to ground

Injectors
(Bosch  0 280 155 897)
(VW/Audi 06A 906 031 S)

R = ~14 Ohm (cold)
R = ~5 Ohm (warm)

317cc/min (30,2 lbs/hr) @3bar
(3bar FPR 06A 133 681 B)
369cc/min (35.1 lbs/hr) @4bar
(4bar FPR 078 133 534 C)

Interesting links:
- Injector flow rates
- some 20v injector theory

1. switched +12V
2. MS (pin 32-35)
 

Wastegate regulator or
Boost control valve
(N75)
(Eaton)
(VW/Audi 058 906 283 C)


R= ~30 Ohm


● When there is no electrical signal, the long connection is closed.
● The two short connections are connected to each other.
● When actuated, the link between the long connection and the two short connections is opened.

Fuel Pressure Sensor (0-10 bar)
(VW/Audi 06E 906 051E)
 

1. GND
2. signal
3. +5V supply

Pressure [bar] = (2.47 * U [V]) - 1.12

This will however not be my end situation as I want to have some more functionality:
- wasted spark COP control
- fan control
- boost control
- table switching
- tacho output
- knock sensor input
- shift lights
- launch control
- EGT logging
- Fuel pressure logging
