Just got my E36 running on speeduino, what a difference MAP based load makes! The vane air flow sensor really made the car sluggish. It's completely stock so this should be a good starting point for anyone with an M42.
I wired it all in to be plug and play with the Nissan RB igniters, this way I can still swap in the old ECU.
Here is some info I collected and settings I used:
Injectors
Part number: 0-280-150-714
Flow rate: 191.8 cc/min, 18.25 lbs/hr (@ 3 bar, 43.5 psi)
Impedance: High, 15.8 ohm
Color: yellow
Reference: http://users.erols.com/srweiss/tableifc.htm
Crank Trigger
Teeth: 60-2
First tooth pulse after the gap is 114 degrees BTDC.
Speeduino trigger angle setting: -114

Cam Trigger
Teeth: 1
Trigger angle: 144 BTDC before cylinder 1 power stroke.

Coolant Temperature Sensor
-10 °C: 9 kΩ
20 °C: 2.5 kΩ
80 °C: 0.34 kΩ
Reference: Bentley manual
Intake Temperature Sensor
-10 °C: 9 kΩ
20 °C: 2.5 kΩ
80 °C: 0.34 kΩ
This is inside the vane air flow sensor, so wire in another one if you want to remove that.
Reference: Bentley manual
Idle Valve
Frequency: 100 Hz
DME Relay Circuit
You'll need to make a circuit that turns on the DME relay, this was done by the stock DME originally. I just copied the circuit from pazzi88s plug and play board. I used a PN100 transistor instead of the 2N2222.
Pinouts
Everything works except tach output and I'll update this when I find the issue.
I connected all the grounds together, not sure if there will be less noise running the ignition grounds separately.
