so does the stock NA ECU.

Right so that would be a problem which is why i'm trying to find a workaround.

Braineack 08-30-2013 06:22 PM

there are plenty of people running them at the dwell without issue, and if you needed to for a week or so, that wouldn't be a be deal.

Just thought I would put this here: 01 Miata COP solution. Honda K20A coils and they have built in igniters. This is all the information I have been able to find so far.

How much power do they produce?

300zxrb26dett 09-12-2013 08:52 PM

no idea about that but this thread looks promising:
K20a Ignition Coils information needed. - Honda-Tech

So many k20a coils and not a single result giving an output? Da fuq is this shit?

My workaround is to carry a 5th coil in the jack well.

If you aren't in a hurry for an answer, I can put a note in my calendar for 2015 to let you know how it is going.

Thats the thing, odds are more than 1 coil will be damaged.

Why more than one? I'm no quality guru, but I think it all comes down to MTBF, and there is almost always some scatter.

I would agree that if one failed, I would immediately get another spare and if another failed in short order I would replace the rest of the set. But I don't think there is anything that would cause cops to fail like dominos. They all see the same dwell, they all see the same voltage. One dropping out shouldn't stress the others significantly.

To draw a parallel using Miata parts, I know plenty of people that have taken the good half of two coilpacks and put them together without issue.

triple88a 09-19-2013 09:09 AM

Because you're overpowering all of them together with the excessive dwell and since all of them are made to spec i'd assume all of them should burn out fairly close timing of eachother due to the extra dwell.

Am I throwing money away if I buy the Trackspeed kit?

Trackspeed Engineering

I really don't feel like piecing together everything separately... Maybe I'm just being lazy, I dont know lol... $300 dosen't seem too bad for a PNP set-up with the bracket and everything

Well, its about $40 for all the wring, about $100 for the cops, free-$50 to make the bracket. But if you don't have the proper crimp tool for the wiring connectors add another $100 to $250 onto that depending on how nice of a crimp tool you want to buy. Of course, then you end up with a high quality crimp tool which will make you fear no automotive wiring job in the future.

I have a soldering iron and would probably just do that lol .... I also have a wiring harness lying around from an old totaled fleet vehicle here at work. Hmmm So I would probably just buy the Trackspeed bracket because I dont have any easy way to DIY that. What vehicle's are people using the COP's from? Are all Toyota COP's the same?

triple88a 09-19-2013 09:41 AM

Made my cops for under 100 bucks. You dont need a magical 200$ crimping tool.

Yes you do, solder is not allowed here, nor are hardware store crimp terminals.

Ohhh interesting. Info on where to purchase this Magical crimp tool and special wiring connectors?

Leafy 09-19-2013 09:49 AM

The required parts are posted in this thread. Take your pick or crimpers that work with sumitomo terminals, you can get by with a cheaper crimp tool that doesnt ratchet, but even doing the 20 or so terminals for this harness you'll wish you bought a ratcheting one.

You mean you are only going to spoon feed me 1/2 of the answers?!?! :rofl: I'll take what I can get haha Thanks

Just enough to give you a taste and keep you cumming back.
