however, it's a shame that the connectors will cost more than my coils...I see a date with epoxy in my future.

For a few bucks each, I would be cool with it. For over $100? Solder-on terminals, wire, and epoxy. Atleast I have a PNP connection at the car side of the harness.

For the two people that were interested, if you guys still want to paypal me $40 to build harness for you guys, I will. They will be nicely done, ready to plug in, soldered, heat shrunk, ground wire will have a ring terminal, connections labeled, etc. If you send me your ignitor, I'll open it and solder the leads on to it, like how I did mine. If not, I can solder on some terminal pins.

Sorry, took your initial response as somewhat snippy when I feel I was asking a valid question.

$40 to you or $67 to GM.... you need a better price break my friend :)

Just a few questions with this setup.

1. Does anyone know if this setup is actually stronger than the stock 1.6L ignition setup. I know the benefits of not having to run plug wires and noise, but in terms of actual spark voltage/power, is there a definitive answer. I'm contemplating with my turbo setup to go this route or to put an MSD DIS-2 system in. I'm having misfires running at 15psi now.

2. I have an AEM EMS. Are the dwell settings the same for this ignition setup. Anyone know what it should be?

Hey newguy, you need to lurk moar. And also read the rest of the thread. This thread is an encyclopedia of nollij.

I've read all the posts, questions aren't answered. Do you know how much energy per spark these coils produce? Since you've changed the settings on the AEM, were they different from the stock miata setup? Is the dwell setting for the 1.8L miata different from the 1.6L?

I'm sorry if I seem rude or I'm asking questions that seem to be difficult. Many people post things and says it works for them. I tend to like to know what I'm putting into my car and why. I know you've had good results from your setup, however you have the ability to change your dwell settings to the corolla default which is the correct way of doing it. However, I see people with stock ecu jumping onto the bandwagon. I'd think they would like to know if this will fry their coils.

As I mentioned before, your going from one stock ignition setup on a similar NA car to another stock ignition setup from a different manufacturer. The new setup many not be as strong as what mazda had.

lazzer408 08-08-2007 05:18 PM

In the thread it's been posted that I had them working using the miata settings in my ems without overheating...it's also posted to use the dwell wizard and choose the toyota coils (scion tc ect). It's also posted someone is having the coils tested to see what optimum dwell is and what the output power is. Why cop? It's been posted that the engine runs smoother, eliminated the plug wires, increades the gas miliage, and there cheap. As far as coil strenght? How about firing a .080 gap with 12psi on a fried plug? I posted the pics. Or the fact that open air it'll jump 1.25-1.5" ark length? What more do you want that hasn't already been answered in the thread? I know it takes alot of time to read 400+ posts but I myself have spent alot of time figuring this system out and providing any and all information I have about it. Not to mention writing alot of the posts. I'm not about to answer it all for the 10th time. Sorry to be harsh but that's what forums are...reading.

Ben 08-08-2007 05:40 PM

Red, we'll have hard numbers soon enough. But the data aquired so far is positive.

It wasn't $67. It was 13.79x4 + 2.71x16. That's $100, and for just pigtails. I offered to make a whole harness, from end to end. And really only for 90-93 because I don't have anything else in my driveway to test fit and test run each harness on. And after I buy materials (lots of wire, heat shrink, pins, etc) and pay postage and paypal fees, I'm probably going to see $5 profit for what is likely 1-2 hours' worth of work. Hardly a money making scheme, more like a favor for those who can't do it themselves. The chance for profit certainly wasn't my initiative. And it damn sure isn't an incentive.

oh you were adding in the "could be terminal". my bad. i thought it was a set of pins and connectors without wiring for 13.79.

damn ben you're right! please forgive me.

still... i have hopes of finding the OEM for the connectors and ordering samples. that'd be schweet and save you some work.

Red 90 08-08-2007 06:30 PM

Ben,

Thank you, hard numbers would be nice.

Lazzer408, I don't mean to critisize your setup. That's not the intention. If you read my post carefully, I did mention I know the benefits of the COP setup. I was asking about spark strength numbers and compatibility.

I can put on GM coils on my car and it'll work. It'll fire up and run smoothly, but eventually I'll fry those coils cause the dwell settings are shorter than what the stock system is set at. My point is things may work for a while, but if you don't really understand what your putting into your car, your taking a risk. Your covered in that you've changed your dwell settings with the AEM. Those that don't have that liberty may fry their coils. If your so confident on the settings are the same as stock, why did you even bother changing it to the toyota setting. Might they be different?

Your results of smoother, better mileage etc as I had said can be due to many factors including the fact that your stock coils may have been on it's way out.

In a few days we'll have optimal dwell numbers for the coils as well as an idea of their output.

Ben 08-08-2007 07:45 PM

as well as a comparison to 01+ coils. Should be cool.

beerslurpy 08-08-2007 08:21 PM

Hmm so I can take these dwell numbers and... oh right, do nothing because the Link can't adjust dwell.

I heard that ray changed the Link for FMs race car to tweak the dwell for the coils the used. Shame I am not a firmware programmer.

Braineack 08-08-2007 08:37 PM

sell the link, go MS! :gay:

beerslurpy 08-08-2007 08:40 PM

If I end up in a state that does OBD2 scans, I am screwed, or at least will have to go through a major hassle.

Ben 08-08-2007 08:43 PM

don't understand... do you have a Link piggy? I wouldn't expect any piggy to have any dwell control. But you could run a parallel ms ecu, like what cjernigan is doing.

My coils are fine. As I said before I was running COP in wasted spark setup for over 1000miles using the stock Miata dwell. No problem. You can do what you want.

"I can put on GM coils on my car and it'll work. It'll fire up and run smoothly, but eventually I'll fry those coils cause the dwell settings are shorter than what the stock system is set at." I thought you had an EMS. ;)

I'm running the standalone obiwan link. I wouldn't run 18 psi on a link piggy. That is like pulling the pin on a grenade.

What is the story with those GM connectors? Are we still waiting on someone to figure out if they fit? I can't wait to have my car running again. I decided to wait on turning it over until I get the new coils in.

The 1.8 coil system is one giant block of epoxy with no way to disassemble. The plugs are permanently attached. It looks like I'm either going to need a connector of some sort or I'm just going to have to snip into the wires.

Does anyone know where to get a male plug that matches the pattern of the 1.8L coil packs?

I was speaking for people that would be running this as stock. Plus the stock igniter's current limit is different, so I wouldn't be utilizing the GM coils properly anyways. If I am to do it, I would run the same setup as you are with sequential fire on the AEM EMS. It's a pretty slick setup. I just wanted confirmation if this is better than the stock setup and how much better with regards to spark energy.
