I have no problem firing the COPs with megasquirt I just want to know if my Tach is going to work or not when i remove the stock coils someday.

I gotta order parts to make a few boomslangs. the .070" ecu pins should work in those harness we bought. Just gotta find a source for all the parts i need, i can buy a few here and a few there, but with these minumim $$$ orders I dont wanna do it that way.

fwiw, i just pussed out today and started wiring directly onto the coils.

I sent Y8s a Packard Electric pin yesterday I had that fits on the COP lazzer sent to see if it will work in the Toyota housing. The housings I have are only 3 terminal and have a rounded shape (like the GM BCS) so they won't work even with some modding. He should have it today. I've probably got about 50 pins and I'm sure they're probably cheap from Packard Electric if I can get a part number. I got them loose in a big electical/connector/crimp stuff toolbox I got with the car so they have no packaging for identification.

I aslo went to radio shack and bought a 22-pin connector with pins. I wanna see if they work, cuase if so it's a $2.50 solution. plus the $27 shipped for the connectors, you are looking at a total of $30.

fwiw, i bought about 100 extra ecu pins if they do work.

COP Mounting Options?
 

I shot a note off to the guy that had the nice page with the COP plate to see if he is still making them (price and availability)... anyone else have a source for a clean COP plate? No, not JB welding nuts or studs on my cover. :)

Thanks
Wallyman

a sheet of alumin and a 1" hole saw will do it.

drill the holes for the three oem valve cover bolts, drill the 4 spark holes, and then drill 4 holes for the cop flanges.

then get 4 nuts and bolts, get bolts with a very shallow head stick up from underneath plate, and attach with thread locker and nut from above.

I was going to mock up a protoype COP plate and take it to a machine shop to have a run milled for general distribution, but there was not enough interest. only 2 or 3 guys wanted it, would probably need to get like 10+ involved to make it cost effective.

yeah if I get it today dont expect much of a fanfare. our mail man came last night at 11pm. wtf.

I have access to a CADCAM plasma cutter. If i get the time to do so i'll make up a design to cut them out of flat sheet. I'd probably make them out of mild though and people could paint them whatever they wanted. Aluminum might be an option as well. But like i said, when I get the time.

you guys like over engineering.

Sometimes we do. I just like the idea of using the plasma cam. I'll probably still make one for myself. Drilling holes is pretty simple though.

Frank!
bad news....

it fits the coil pins fine, but it's WAYYYY too big.

Hmmm
 

Well, that would be easy enough, I guess. I like the idea of just buying the pre-drilled piece tho (lazy). I think it looks great and someone else already engineered the thing so if the price is right....

Regardless, hope to be COP-ped in a week and a half when they get here. $42 for a set of 4 off eBay, quite please (assuming they are right, ha!)

Wallyman

Matt, can you measure the width of the pin you got?

great news.

the contacts I bought work for the toyota connectors and fit onto the cops (.070" contacts tyco PN: 173631). So you're looking at around $27 shipped for PnP connectors, and a dollar or two for the contacts from me. not bad.

if you need 16 pins let me know. i ordered about 100 extra or so.

sweet... scott, how many extras will you have? i've got a few harnesses to make :)

i think i got enough for 11 harness. two of which are spoken for, mine and y8s of course.

lets see, i bought 296 of them (think i got more), need 96 for my boomslang harnesses, that leaves 200 left over for coil connectors, and i need 32, so 168/16 = 10.5...so enough for 10 yeah.

not everyone needs tach output (like me) so you can save a few that way. but I guess I'll still want 16 just in case.

I'll take 10 male pins. I can paypal. Please email me at soflarick (at) bellsouth.net as I haven't been receiving email notifications from this forum. Thanks.

finally done with this bitch:

Nice work Braineack.

Oooohhhhh that looks nice. Guess I'll be doing mine with some insulated heat shrink bullet connectors.

What's your plan Y8s?

Looks tizzzight!

i'm getting some pins from brainboy to put in my toyota connector housings and i've got 37 million feet of various loom sizes or a trip to www.wirecare.com (omg stainless zip ties!) and probably something similar to what scott did. then run the four back to the proper hydra pins. i may need to get more crimp pins from FM though.

Speaking of crimp pins.
I am fixing the mess that the prevous owner made of my stock ECU harness. In the process one of the wires fell apart right at the crimp pin and I don't know how to get the pin out. I was under the impression that you just insert something into the little hole and pull the pin out. I used a needle because it was the only thing small enough to slide in the hole and I still can't get the pin out. I think i need a paper clip hammered flat or something because nothing else is small enough to get in that little slot.

I am still waiting on 2 COPs from lazzer, i did get connectors out of the deal but it sucks being short 2 coils.

if i recall, the NB connectors have a "latch" in them. let me see...

http://ecommas.tycoelectronics.com/c...1-5763-1_A.pdf

page 7-9, figures 11-13.

Matt

Mine look a bit different than those, though maybe all i need is a stronger more flat tool that I can pry up with. I'll try it in the daylight. If it doesn't work i'm soldering directly to the outside of the pin and closing the door latch on the back. It's just the idle wire anyway.

Braineack,
So are you gonna throw together a few harnesses for locals? I'll throw some bucks your way. Make mine exactly like Y8s. I got an NB. :) Don't need a tach signal if my reading is right.

Frank

Braineack,
I'm interested in getting the connectors. I just picked up my last to coils yesterday and I'm getting ready to make the harness. Are you selling the just the pigtails or a whole pnp harness? I can probably get like 5 ignitors for the NA's if you need them.

Talk to Ben, im not making these harnesses. Busy building Megasquirts.

Braineak,
Are those the same connectors that 'y8s' is using, Toyota part number : 90980-11885. If so can I get 16 of the pins and I'll order the connectors from the website he listed and I can make my own harness. Thanks

Just to gloat... I got connectors! :p

Braineak - I'll take a set of pins
 

Braineak - I'll take a set of 16 pins. Can Paypal, let me know here: wallyman (at) miatamonkey (dot) com. Thanks!!!

Connectors
 

x2

Is 90980-11885 the connector in those kick-azz photos??

Wallyman

yeah I'm makin' my own. And before you ask--it's way low on the project list ;)

Man. you guys can't click back a few pages? This fits the coils. pins separate. Braineack needs to post the p/n and then you can all buy them at onlinecomponents.com and distribute them amongst yourselves because they have like a $30 minimum which adds up to fifty jillion pins.

Since my car is running OK, this is really low on my project list behind epoxying my garage floor this weekend, putting in a 4-post lift, installing a sprinkler system, and re-tiling the bathroom. At least the COPs look good sitting on my work bench.

Frank

Funny how your list and mine are so similar. Except the lift installation. I go use one of my dad's. :)

i did.


time to create a page for the archives. :bang:

partznet.com was $1.75 cheaper (shipping) than discounttoyotaparts.com despite them appearing to be the same website (or at least ordering engine).

I couldn't find a valid 10% off coupon code. All were expired.

Braineack,
Do you still have 16 pins available? Can I paypal you some bucks for them.

Frank

lift?

Part #'s
 

Connector
Y8s found it: Toyota 90980-11885

Pins
Braineak found it: TYCO 173631

Braineak - Did you have spare pin sets to sell, or no? If not, I guess I need to order 50 bajillion myself so I can use 16 of them. :)

As much to store the car in the winter as to work on it. 4-post 'cause I can move it around and it doesn't take as much height requirement. I can always use jackstands or the jack tray for brake work.

i think this will suffice for now.

Braineack,
Can I get some pins from you too if you have some left?

Thanks,
Frank

yes PM if you need them.

I placed an order for 400 extra of them. That makes more than 20 harnesses. Would require $3 in paypal from you guys to cover the pins, and stamp.

Are you running on COPs yet scott?

it running, havent actually driven the car yet :rofl:

This is one of those things someone should put into a faq or pdf....

Brain whats your paypal?

loki check archives.


here's my final results:

How thick was the aluminum you used?

Your mani and turbine housing make me want to get mine coated.

Any pictures/dimensions of the plate you made?

making the plate is simple.

I used 22g alumin. (pretty thin) got a sheet for $3.99
4 nuts and bolts m6x40
1" hole saw

https://www.miataturbo.net/~web1_bra...cops_plate.jpg

i didn't take precise measurements, but that shows you what to do. I put a bit grease on each of the three valve cover bolt holes and laid my strip down. this marked the positon of each to drill out. once drilled i measured from each hole i made for the spark plug holes. very simple, something like 1.25" away center to center. can't remember. once done, I laid it down, stuck the cops in and marked the position of the tabs with a pencil. once drilled I stuck the m6 bolts up through the holes and laid it on the valve cover. put the cops over that and and bolt it down. the ruber gasket on each cop squeezes in and the nuts stay good and tight. the end.

The plate looks good, but I thought the COPs sat directly on the valve cover so that you needed to drill holes in the plate. I guess this is not true? I haven't test fitted my COPs yet obviously.

EDIT: Sorry the above post wasn't there when I started to type this reply. Good info, thanks!

EDIT 2: Damn 22 gage aluminum is 0.0253" thin. Wow.

tim does this make more sense:

https://www.miataturbo.net/~web1_bra...ate_screws.jpg

HAHA, you should get a job writing manuals for automobile companies.

it would be butterz if i knew how to you autocad. but, yeah that would one badass manual that no one would use. :(

yeah i know its .025" but it's enough. easy to cut and drill and it's very very secure. I mean these things aren't under pressure or anything.

Tim the connection inside the COP is a spring that contacts the tip of the plug. I haven't actually measured the depth of it but it feels like the spring is bottomed out when I installed mine against the valve cover. I'm sure there's at least 1/4" of usuable extention of the spring to allow plate mounting the COPs.

damn dude, that looks great.
put me down for 3 sets of the pins, please. thx
