That is a good point.

Once my junk is back up and running, I'm doing this.

we should mock up a plate and get a few of them water jetted.

anyone near me have a spare 1.6 cam cover I could hang on to for a couple weeks?

what?! This looks like a job for zip ties and JB Weld! :gay:

iv got this ginormous sheet of Al sitting in my living room that was gonna be the base for my front under tray. I think it can spare a short strip for use as a COP holder.

I run between 10-15psi and just changed my plugs. They were gapped at .045" ! I thought I had them at .032". So anyways it's firing a .045" gap under boost.

That's my kind of news. Kickass.

Hey braineack in on it now? I must have started something good. :bigtu:

Ok, so installation pics on a 1.6.

Step 1: Cut out your igniter box(leaving enough wire on the plug just in case things get fubar). Relocate the EGR plug and ground wire to the front bolt hole for the mounting plate of the igniter. (Is 1/2 hidden by the big wire loom on the right). Also tape up the red and white wires, you won't need these to be connected to anything anymore.

Step 2: Get your connecters and label them so that they follow this pattern (TOYOTA PLUGS/CONNECTORS ONLY, anything else may be different)
http://www.ilostmymind.com/upload/step2.jpg

Step 3: Using Lazzers diagram FOUND HERE wire your plugs together and add the required length of wire to reach where the igniter box was. It's best to use 12gauge wire for power and ground and 16gauge wire for the trigger and tach. *Also, note the extra ground wire and how the coils are numbered (it's a good idea just to ensure you don't mix anything up while connecting all the wires)
http://www.ilostmymind.com/upload/step3.jpg

Step 4: Here a good ground location for the extra ground on the head is shown (it has a bolt in it, it's just removed in this picture)
http://www.ilostmymind.com/upload/step4.jpg

Step 5: Using Lazzers diagram again, connect the Ground, Triggers, Tach, and 12v to the wires that were going into the igniter box.
http://www.ilostmymind.com/upload/step5.jpg

Step 6: Wrap all the wires in electrical tape and tuck them away however you like.
http://www.ilostmymind.com/upload/step6.jpg

Step 7: The plugs will vibrate up off the valve cover if you don't fasten them to it. You can still drive the car, but doing so for an extended period of time will cause some problems. This parts up to you how you'd like to do it. I'm planning on JB Welding(or just regular welding) on 4 nuts to the valve cover and bolting the coils down to them.

Enjoy!

there's no reason not to! especially at the price tag.

Instead of modding the valve cover... what about making a plate that holds them from above... and bolts that go down to the plug wire 10mm bolt locations?

yar, that be wat im gonna do matey!

Anybody been able to source the plugs yet?

You mean the connectors? Re-read the thread if you're looking for plugs, it mentions a couple places. I got mine on ebay.

Right now the connectors are solely coming from junkyards from what I understand.

Sean do you mean coils? Coils or connectors are both from ebay and/or junkyards.

Nice pics Sean! :bigtu: Worth 1000 words especially pointing out the extra ground wire and location for grounding.

I can find what appear to be the correct COPs easily but I can't find the wires. PM me if you find the harness that hooks up to the COPs. Thanks.

Those of you who already PMed me, keep up the good work.

I did a bit of investigating and I THINK these connectors are manufactured by a company which I've already contacted about the connector. They seem to make connectors ranging from injectors to atx power supply type. (molex) I'll keep you updated. =)

There are a lot of companies (mainly in China) that make a compatible molded connector. Problem is they will have large minimum orders (1000 or3000 are typical) plus you have to wait for manufacturing + shipping time from China. Could take 90 days.

While having the harness would be easiest, what it looks like I am going to do is get some crimp-on/solder-on mini spades and make my own leads. It's not tough: solder on the spades to 4 wires, plug spades into the indiviudal terminals, and fill the connector with epoxy.

I have a Hydra and intend to do this swap. I assume the Hydra can handle sequential coil firing. I have to figure out how to configure it for sequential. With COPs like this, esp from a different vehicle, and firing sequential, how should the coil dwell settings be changed?

Spades suck. Solder it straight to the coil's terminals and epoxy it. :)

that was my plan before seeing the COP, but now that I see it, the connectors are in there pretty deep and my fingers are short and fat.

Tin the coil terminal and wire first then you can just hold the wire in place and tap it with the iron. That's the easiest way in tight places. Or bust out the dremel. =)

sigh... someone find some connectors. I went to 3 yards this morning and found jack shit.

blah.

Jack should have used an outhouse or something.

+1.

I am also looking for a set if anyone grabs a few.

The cars are too new to be in the u-pull yards around here, and the non u-pull ones want to sell you the whole harness.

Group buy on coils!!!

I found a source for 24 units (maybe more). So if I can get 6 people to pay $60 for a set of 4 COPs I can do it.

i think everyone interested would want to know if they come with connectors.

Yep. I'd be in if they came with connectors.

Nope. No connectors... but I tried. =)

I've been meaning to post this for awhile. I just took some pics. Take it back a few days before I did COP. I had this ocassional misfire under boost which I attributed to "weak Miata ignition" I kept reading about. I switched to COP and the misfire went away. After COP was on and working I ran the car a few weeks to see how it went. Not one misfire. I decided I should pull the plugs and check the color for some visual insite as to how things are running. I pulled #1 (good) #2 (good) #3 (HOLY SHIT!) #4 (good). Autolite plugs in there?!? (I asked myself) I thought I replaced those a long time ago. Turns out I didn't and I've been running plugs that were actually a heat range hotter then stock! Now add the ford probe, non intercooled, no engine management, no ignition retard, detonating diy setup I ran for monthes and I know exactly how this plug got like this. I've been running/tuning on them for over a year now!

Point is... COP fired this plug with 12psi of boost (pig rich@10.6 af) without a misfire. The other plugs were at .045" That speaks quit a bit about how well the COPs are actually working. =)

Attachment 216143

Wow.

Thats amazing, I would love to see pics of that plugged into the COP and firing.

I would like to open my door and find a set of plugs with a harness in a shippiing container of some sort.

I'll get right on that :bigtu:

I'll get right on that :bigtu: :gay:

Since your on that, I would like a set with connectors and a harness aswell, I want PnP!

It isn't a matter of "plug and play" it is a matter of the coils being female connectors with exposed prongs and thus difficult to homebrew a harness.

60 a set?!!!:cool:

Anyone interested in sending some down to Oz? (Nobody seems to want to part with any of these here for less than 250 :eek:)

These may work as well, I thought about them but he won't ship to me either :'(

Lazy Ebayer

PS: Great forum and great thread...
Long time lurker first time poster.
Loving the boosted side of life.

I'll put you on the list. I need 6 buyers (+shipping ofcorse)

lazzer, how much do you want shipped? I assume you're getting them from a junkyard perhaps?

Is there a benefit to these over a stock '01 setup?

Frank

no, not really, unless you have an aftermarket ecu capable of firing sequential ignition, and ran the 2 extra wires.

Next question, who would be interested in a COP plate? Looks like I have access to a local forum member's spare cam cover to make it easier on me, and my plan is to mock up a plate then take the design to a machine shop and have them CNC or waterjet plates out of aluminum stock. But this probably can only be possible if there is enough interest. I'd also look into getting them powdercoated, but we'd need to agree on a single color probably. I was thinking black.

I don't know a price point at this time. I would assume on the order of $100, and maybe $120 or so 'coated, each. But be assured the endeavor is to get enough interest in the plates so that they can get fabricated. This is not a money making enterprise. I will donate my time and resources.

1.6 only at this time, sorry. But I'll also work on a 1.8 plate if I borrow a cam cover.

Comments?

Why yes I do. I'm just wondering from a performance standpoint. I'm not getting any misfires now though, but will up the boost shortly. Might be worth the cost if someone finds a source for connectors.

Frank

Sadly.. I don't think i'd be able to use a plate you guys make. GTX valvecover is going to be custom... woo another part to make :p

And as I suspected, 90-93 ecu pins fit on the cops' terminals perfectly. I'm just going to make my own harness, and suggest others do the same. Hoping that I can find a local source for the pins. Tyco has a minimum order of 1000.

http://img65.imageshack.us/img65/929...insatc6.th.jpg

Next step is finding spades for the ignitor side.

Of course Airtex and SMP corp, who make replacement coils, don't make the connectors.

I emailed 'em.

Frank

Honda Civic's (90+?) uses the same connectors for the ECU as Miata. Source those for the terminals. The ECU is located in the passanger footwell and junkyards are littered with those cars.

You guys mean the pins that connect to the ECU? AEM sells them in strips of like 8 or so. I know I got a bunch with my AEM EMS for connecting various accessories to available terminals. I believe the part number for them is even in my AEM catalog.

If someone would ship me one Corolla coil, I will take it to the lab and figure out its optimal dwell curve.
I did the same for FM for the dwell maps for the Hydra for the NA, NB, and 01+ coils.

what's the part number of the pins?

you can order them at onlinecomponents.com (no min.) and estore.heilind.com

the male pins that would plug into the ignitor harness would most likely be (173631) .070" contacts or (173716) .040" contacts


Would something like this not work? http://catalog.tycoelectronics.com/T...13&N=1&IDS=752

http://ecommas.tycoelectronics.com/c...D_770275_D.pdf

I have the dwell curves AEM suggests. So does Tim.

you guys have the dwell curves for the toyota coils? post up! if not, I don't have an issue with sending Jason a coil.

ben will the plug I posted work for your coils?

http://ecommas.tycoelectronics.com/c...D_770275_D.pdf

the ecu pins I refer to are the ones that slide into the ecu harness, on the car side of the harness. They slide on the pins and actually lock into place firmly. I happen to have 2 from the FM Link installation kit. Need 14 more. Scott, I'll look through those links later. Thanks

<edit> the specific part you listed will not work. too small. the cop connector outside measurement is 1" wide x 7/16" high. 4 male rectangular pins inside. I don't have a micrometer to get down in there but they appear 1/16" wide and .7mm high. They are evenly spaced left and right, but are set up closer to the top of the coil than to the bottom.

Doesnt look like mine.

if you want the reverse of what you are using on the ignitor you posted, then yeah the two part numbers I gave are what you want, you just gotta determine size.

Scott,

I am obviously not Ben, but the corolla coils I have the pins are rectangular, not circular. However my part number is different then Lazzer's. Will post when I get off from work. They seem visually identical. And they are from an 03 Corolla.

And on the tyco schematic it seems they are circular (the female connectors that plug into the obviously male pins on the coils.)

ok, then try this one...I'm just looking at the pics you guys posted and trying to find a match... it's not very efficient.

try this one on for size: http://ecommas.tycoelectronics.com/c...D_178481_A.pdf

that one is close but the widest one listed is too narrow by a few mm. The OD width of the cop plug is 24.Xmm, so the ID of the harness needs to be at least 25mm. the terminal spacing of that one looked pretty good left adn right. as far as I can tell with my tape measure, the pins are 4mm center to center. again, I only have a tape here, not really the right tool for the job.
