Thanks Aidan, I agree with you. For reference, I've been watching this video:
; reading this thread: https://www.miataturbo.net/diy-turbo...-thread-82744/ ; and this thread: https://www.miataturbo.net/adaptroni...1/#post1005789

Are there any other or better references that I could use that you may be aware of?

:flame suit on:

Hey ya'll just wanted to offer an update. The NAPA ECHLIN IC413 coils are made in Poland. But that doesn't matter because my misfire issues where from hamfisting my plug wires. They are tender at the 90 and where breaking/broken apart.

Escalade wires work well in a bind, haven't had a misfire issue since.

My next issue is possibly fuel and airflow related. But i'll take that offline in another thread.


Moral of the story:
Check your wires
And still, just get GM Take off's or OEM Delphi over other.

Buy these ends from Summit and be done with your troubles. I used them on stock Miata wires to go to my truck coils.



I use the stock wires but used the Taylor ends from Summit Racing on the coil side and shortened the high tension leads to match my needs.

45s don't look as good with our style of bracket.

That's what we had. But the 90* ends that magnecore suggested broke for both payam and I. You need to have a gentle touch with them. Which is why we are working on replacements.

Quick question in regards to wiring.

OEM has a 12v and ground going to each coil. Do I wire both 12v (black/white) wires to the pink wire and both ground (black) wires to the brown wire. Or is only one 12v and ground source sufficient for all coils.

Default Are you sure the power wires are thick enough???

Are the "Black/white" factory power wires a large enough gauge to supply current for the D585 truck coils? It seems awfully small for the whack these coils are supposed to give out. I just can't imagine a GM truck having wire that small driving 4 of its coils in its factory loom. Has anyone ever wondered about this?

Dwell vs. RPM:



Dwell vs. Battery voltage:



Without a 3D table like the GM ECU has, you're stuck with two linear 2D curves. The battery curves are correct for everything above ~5000rpm and a little low below that, but since these coils discharge with excessive dwell at high RPM, I felt it was better to stay on the conservative side everywhere. The tables above will never produce a dwell figure that's higher than the OEM table, which is what I wanted.

I have cranking dwell set at 4.5ms and the car cold-started in my 68*F shop, but YMMV.
exactly what i was looking for

Hey folks, I'm building a harness for my D585 coils and I wanted to pickup some capacitors. Last time I built a harness I picked up parts from my local RadioShack but as we know they're not really around anymore. Anyone have a suggested vendor for stuff like that?

I though most people were omitting the capacitors these days?

I tend to buy electronic components online these days from Element14 or RS Components but due to S&H costs prefer to wait until I've got a few things I need - paying more for S&H than the goods themselves just doesn't seem right. I usually end up ordering 10x what I actually need too (eg, rather than 1 trim-pot, I get 10 since they're cheap enough)

Yeah, hard to not buy in bulk for components like those with the cost of the shipping. If that's the case I will run without the caps, I know it was suggested pretty heavily when I built my COP harness but they're kind of in the way so not adding them in works for me.

amazon, ebay, digikey, or mouser depending on where the deal is after shipping. Generally buying 1 thing amazon or ebay are cheaper.

Do we have a wiring diagram for mspnp with sequential wiring? Do I still need to mess with the igniter? Im assuming wiring is all the same but run all the signal wires to the ecu?

We didn't add capacitors into the FlowForce PNP harness. It's not needed.

Is anyone running MSD replacements for de LS coils? Like the MSD streetfire ones. I need nee coils for my turbo build. About 300-350hp. Those are easier to get over here in the netherlands then OEM ones i think

Turned out my LS coils i have now are fake.
