Coil on plug

[gsmith660]

Need suggestions on COP setups that work on megasquirt 3

[gsmith660]

I have megasquirt 3 so they would need to be compatible with that

I use toyota COPs, they work very well with Microsquirt.

[gsmith660]

Model number please

[kamaro]

Toyota 90919-02246 .. The set I got is a knock-off which I got for about $70 for 6 pcs, I thought I will first use knock-offs so if I did something wrong (excessive duel, driver burn .. etc) its cheap to replace and eventually I will get the OEMs, surprisingly and after about 3 years they still running fine.

If you want to be certain to get the right ones, check with Chris at TurboKraft, they sell Smart Coils that just need a signal wire to fire. The Dumb Coils need the HC (High Current) output from the ECU to drive them.

I found trying to order COP's from various internet suppliers had mixed results and were sent slightly different p/n's that 'should' work. They're not cheap either: In the $60-$120 range each depending on who sells them to you.

You're looking for this p/n: 90919 02234 but it may have been superseded by what Kamaro is using -02246. This is a smart coil. This is different than the 'dumb coil' which is used with the HC outputs on the MS3Pro EVO+ HC

Here's a link talking about COP ignition here on the forums:

I am running 12 Toyota 90919-02246 COPs in my 3.6 (not turbo) and they have been faultless for 15 years. Cheap too.
You will need Toyota connectors 90980-11885.
I cut the mounting lug off the top row of COPs 'cos it isn't necessary to hold them in place and looks neater, but fabbed a mounting strip to hold the bottom COPs in place.

Here's a link to the differences in most of the COP's that we'd use (on all but 3.6L).

If you want it to look pretty, you'll need two different part numbers because of the angle of the connector on the -02246 coil. When installed on some of the cylinders, the angle becomes more obtuse and gets the harness hanging out in mid-air. Can be a problem with a twin turbo setup on the lower coils.

I am using Bosch COP's for my build. Simon from Motec recommended them (his email is below with data on the coils). I will simply use modified OE lower plug wire retainers to hold them in place.

From Simon Wagner (Motec)_____
"here's something I have had a number of our Porsche-centric dealers use with success:

Dual Bosch 0 986 221 024 coils on one output
Dwell 1.7ms for 10.4A at 14v
Overdwell is 19.2A
Coils are said to fit a Porsche twin plug head perfectly (they fit mine perfectly)

Pin-out

1 = switched Ignition Power
2 = logic ground
3 = EST signal
4 = Igntion High Curent Ground

8v = 7.0ms
10v = 3.0ms
12v = 2.2ms
14v = 1.7ms
16v = 1.4ms
18v = 1.2ms

Will these work with megasquirt 3 board version 3.0?

@gsmith660, these only require a logic signal that would normally go to an ignitor, so I don't see why not if the MS3 has an ignition logic output.
