Overview
Multi-coil Lead type, example EDIS
Coil-on-Plug type on A12 engine
Cleaner wiring. Looks cool.
C.O.P. - $25 each @ Jegs
Create a simple bracket (like a fuel rail kindof) that the coils will bolt to, and which bolts to the engine or valve cover. This supports the top of the COP units.
Can be used with MegaJolt Lite Jr., just wire 1&4 together and 2&3 together.
Or can be used with other ECUs in spark-only mode.
If your controller doesn't support firing the plugs directly, use an Ignitor box.
Input Trigger
For the simplest easiest setup use the standard distributor.
Which type you use depends on your ECU. MegaSquirt can do all types.
Standard Distributor
Input trigger: negative terminal of normal points distributor.
Electronic Distributor
Input trigger: negative terminal of electronic distributor
Nissan Optical CAS
CAS is not necessary for COP. Use your ECU in wasted spark mode to fire two plugs at once. Non-wasted doesn't make more HP.
See main article: Nissan Optical CAS
With Nissan 360° CAS, use MegaSquirt 3 with 1.3.3 software. This includes SR20, CA18DE/DET CAS or the D4P distributor but modified to fit in A-series engine. See MS3 pre-1.3.3 beta 5 released (urgent for Nissan CAS).
MegaSquirt 2 will work if you swap the trigger wheel for a 22-1 wheel from DIYautoTune.
Crank Trigger
Crank trigger is not necessary. You can run COP off a standard distributor.
If you want crank trigger use:
* Magnetic Sensor * Magnetic Sensor (Hall Effect type)
The difference is that the Hall Effect type has a built in amplifier in the sensor, to create a standard voltage signal before it is sent to the ECU. A plain magnetic sensor sends the raw signal to the ECU which has the amplifier built in.
Magnetic Sensor is very reliable, it is used in millions of production vehicles. However, older/cheaper ECUs may not have good amplifier so require a Hall Effect sensor.
* Rotating magnets. Drill pulley and insert with expoxy or * trigger wheel as low as $8 bolts to the standard pulley. No welding required.
Ignitor Module
If you run COP with built-in ignitor, the modules are not necessary.
CA18DE Ignitor
Use MegaSquirt 2.0 to control the CA ignitor. MegsSquirt 3 can directly drive COP, but by using the ignitor it will work with MegaSquirt 2.

One plug has 5-wires -- 4 inputs low current triggers. The odd pin is for ground/earth. Connect two to Megasquirt:IGN1 and two to Megasquirt:IGN2.
The other plug has 4 high current outputs to the four coils.

Trigger on rising edge? Trigger on falling edge? Output: logic level Type: wasted spark
SR20DET Ignitor
The SR unit is smaller, newer but works the same way.
