Coil on Plug for your Datsun. Can be used with carburetor. Most newer ECUs, including MegaSquirt II or MegaSquirt III can be used as a spark controller without EFI.

Overview

Multi-coil Lead type is not COP
Album 17184

Coil-on-Plug type on A12 engine
Album 21824

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.

Bracket on Datsun L28 engine

Can be used with MegaJolt Lite Jr. (EDIS), just wire coils 1&4 together and coils 2&3 together. Wire them in series. 12V -> Coil 1+ -> Coil 1- -> Coil 4+ -> Coil 4- -> to EDIS trigger.

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)

See main article: Crank Trigger

The difference is that the Hall Effect type has a built in amplifier 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.

^POST http://datsun1200.com/uploads/photos/17128.jpg

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 plugs which include a built-in ignitor, a separate Ignitor module is not necessary. However, many (most?) setups require an external Ignitor module -- for example, CA18DET and SR20DET used coil-on-plug ignition which require an ignitor module. Also, while many newer ECUs can fire coils directly, older models like MegaSquirt I & II require an external Ignitor.

Common COP ignitors include:

* CA18 ignitor
* SR20DET ignitor
* Bosch 211 ignitor

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.
