capacitors added as voltage feedback shunts to help deal with noise. basically soldering one lead onto the individual 12+feeds and the other to ground. Many OEM's add capacitors to waste spark systems even to help reduce noice (ford,mitsu, ect)

you spec .1uF capacitors. that writeup you linked says 10kuF caps. is that just what the miata's need for their ECU?

and fix the pics!

Still using them on my car. They work perfectly fine.

I wired them directly up to the MS3X spark outputs, no caps or anything.

All nice and neat and tucked under the 16V plug wire cover.

Yeah. I like how they fit under there. Cleans up the motor a lot. Plus looks more "OEM" for that "what is going on with this thing?" Effect

Anyone tried VAG1.8T Coils? They do fit also and cost 30 bucks new

A little comment that may or may not be relevant : as the ex-owner of a 2009 Corolla, I would not recommend the use of 2009 onward coil packs as they corrode quickly and are pretty expensive to replace. Mine had to be replaced every winter.

I've had great luck with wasted spark and the DSM coils, and coil on plug with the GM ls2 coils. well, one coil went bad shortly after install, but after that.. I think I got 12 ls2 coils for like $100, so..

If you wanted to be creative, you could do a wasted-COP setup. Our 4Runners have COP's on the right side of the V6, with terminals and wires that lead to the left side.

What about these CBR600 cops used by the Buchkas? Do they work OK? They are pretty cheap on Ebay.

I would recommend some kind of retaining device for those coils. Mine vibrate quite a bit while the engine is running. In terms of performance they're good. There are lots of guys making lots of power with these coils. Good friend of mine is making over 600whp with his.

so anyone have a good diagram to wire these things up?
or am i over-complicating things while im looking at all these miata diagrams...?

Coil Pin Out

1. ground
2. trigger
2. tach
3. +12V

Like said before these coils have a built in Ignitor so no need for use of the internal or external one.

Here is some info on specs for them LINK

so for people who have had success running these with megasquirt, did you use the .1uF cap (as listed in this thread), or the 10,000uF capacitors that some are listing in the links posted?

When I had mine working I didn't use caps. Just straight to the MS.

No caps on mine either. Switched 12V+, ground, and signal wires straight to the MS3X ignition outputs.

Maybe they'd be a little zappier with some caps, but I have no perceptible issues with 20 psi/7000 rpm/E85.

Toyota wiring harness colors:
1-ground (brown)

3-tach (blue with yellow stripe)
4-V+ (black with white stripe)

Connector
Toyota 90980-11885

Pins
TYCO 173631

Those are the pn others(miata board) said worked and what I tried. I couldn't get them to work properly. I couldn't get them to work properly because they require slight modification to the pin. I'm going to give them another go.


And the miata FAQ thread: http://www.miataturbo.net/forum/t12704/

Dwell curve thread: http://www.miataturbo.net/forum/t11744/
Rookie question, when wiring these in, would you tie all the grounds together? Tie all the +12v together? Run each trigger to MS and just one tach wire to a tach?

Holy bump, Batman!

I'm struggling to get clarity on this subject. My first thought was Toyota coils, but that seems to be easing out of fashion. I'm tempted by the VAG coils, as they seem plentiful here, and I've done enough miles in a 1.8T to not be worried about their lifespan.

So is there a consensus on the best way to proceed at present? Priorities are neat fitment, plenty of spark power, and good lifespan. I'm thinking that the latter two will be covered by more or less whatever we choose (except anything from a Renault!), so my main concern is fitment. What fits best? To keep it in the family, do whiteblock coils not fit?

cheers

James

On my car: Corolla COPS on a 16V. They fit perfectly once a tiny bit of plastic has been clipped off each one, and the stock plug wire cover fits over them, Looks neat and factory-ish, just some low tension wires coming out back by the firewall.

1) All grounds to a common ground on the firewall.
2) All 12V+ to a switched relay. Ideally, I should have separated the power feeds from the sensors (DSM CAS) and the 'outputs' (injectors, coils, boost control, idle valve), but I didn't.
3) All trigger wires directly to the MS3X ignition outputs for sequential firing
4) Tach wires on the COP's aren't used for anything, just stubs of wiring on the coil pigtails. I'm not sure one of them would run the tach, or all of them (the tach normally sees all 4 cylinders firing, it's wired to the coil). I just ran an MS3X tach output directly to the 240 tach and it worked perfectly.
