OK, so I (Think I) get what wires the V+(Power), Tach, Ground, and 2 triggers are going to be wired to.
V+ to #8 Red
1&4 Trigger to #3 Blue
2&3 Trigger to #1 White
Tach to #4 Yellow-Blue
Ground to #6 Black

My question now is if I cut into these wires before the igniter is everything else gonna work.

I mean I don't know what the wires from the igniter to the ECU (#2, 5, 7) are for. The wiring diagram doesn't say, it just has where they plug into the ECU at.

This is something I may do many years from now when I don't have other things I want to do to the car

i just got back from the junkyard, pulled the connectors off an 04 tacoma, and went to radio shack to buy me a soldering iron and related goodies, heatshrink, wiring loom, etc

SUCESS! how does it look?






it was scary as all **** cutting the connectors off the coil packs, and hoping it would all work in the end but it was a sucess

Awesum flippy. So I take it you grabbed the triggers (before the ignitor) and all is well? I don't know if the pulse AFTER the ignitor is a good idea. Tach functioning normally? How does your idle and wot feel now? Mine seemed "smoother" and seems to help the miliage. I'm still seeing 2-3mpg improvements.

Now look what I've started!! COP mods!!

I noticed your coils are a bit different then the ones I'm using. The connector and mounting tab are inline with center. My mounting tab is offset and the connector is angled upwards. Looks tight though! +10

well it's an 2000, so the my old ones had internal igniters, i didn't have to worry about tach input, i just left that wire hanging just in case i wanna use it in the future. i just finished it today, and i was on empty after doing it, so nothing to tell if i have better MPG yet, i used to have a small stutter at idle, and now thats gone, and it does seem smoother, and it feels to pull a little harder, but it could be me. i was freaked out after cutting the first pack, so i had half COP and half plug wires, and started it up, and it worked so i continued on until finish, i wanna go back in and tidy everything up a bit when i get the chance, more factory looking.

Do you think you would be seeing the same improvements if you were still running wasted spark, or do you figure you are making gains from running sequential?

I am going to be running MS on my 94 in a standalone installation, And I am overdue for changing out my plug wires anyways, so I figure cheap COP ignition wouldn't hurt.

Thanks for the writeup.

I might get some to keep as a replacement set of "plug wires" though... its like the same cost... and shouldn't burn out like the wires do.

It has been done. Looks like I will be doing the same.

The first time I wired it up I was firing them wasted spark just like Flippy is doing now and even then I noticed it running smother. It could be a combination of eliminating the plug wires, stronger spark, and cleaner voltages from the other sensors. The major benifit for me running sequential is per-cylinder timing. I'll be able to tune each cylinder's ignition and fuel bassed on egt.

You are going to run 4 EGT sensors? Or just move one from runner to runner and cap whatever bungs are unused?

I will pick up a set of coils as soon as a deal comes up. <40 USD.

I have kept the budget real low on my build, no need to blow it now on coils.

Tough part will probably be finding connectors with pigtails, all the u-pull junkyards here have nothing as new as a 2000 yota.

If you need help finding those plugs let me know and I'll see what I can come up with. You can always try ebay and search for the engine harness from the car your getting the coils from. I'm on a budget too. Most of what I'm running I've scavenged from ebay or junkyards. I'm slowly prepairing the car for some big HP. Yes I will be using 4 egt probes.

Lazzer, what junkyards do you go to around here?

The only 2 I know of are the one on rt.41 and 173, and City Auto Parts off Washington, just past grand ave further down 41.

but yea, ebay seems to be lacking in any coils for anything less that $20 each :( right now. I guess I'll just have to keep looking...

There's another in Spring grove of 12 that's not to bad. Smaller yard though. Pick and pull is the one off 41 and there mostly older <'98 cars. Toms auto in Hainsville is another smaller yard locally. There's a big one off 176/14 area in Rockford. Sharp parts is still in business but there in Hebron now. There's another decent sized one in Zion and Jantz in Kenosha is pretty big too but there kinda ---- about things. There "overprofessional" for a junkyard aka high overhead=high cost.
Is $80 that bad for coils? A set of NGK wires is about $60 shiopped. Most of those ebay guys will take offers. Send them a message asking for there best deal on a set of 4 shipped to 60002. I'll keep an eye out for some if your going to try it.

lol, no $80 isn't bad. I'm just horribly broke :(

It gets tough trying to find a summer job halfway through the summer...

I think some of the Infinity v8s used them too. Like a q45. Maybe try that search. If you find one grab both banks of plugs and sell the extra set. It's a pretty common coil and there's maybe 3 versions of it that have the plug or mounting tab slightly different.

I did find a couple sets in older nissans/toyotas in the junk yards, but the nissan ones were too fat up top and they were asking $25 for each anyways...

So once again, out of my price range. And I'd rather buy some off a newer car for that much money.

I have been wondering about this for a while now. I have some COPs from a 5.4l Ford motor. I might look and see if those are compatible for this setup. But toyotas and nissans are plentiful here. So maybe sourcing a toyota setup might be pretty easy. I plan to wire my setup in to the harness before the ignitor which is mounted on the fenderwell. I also will tig weld brackets to my valve covers for a clean installation. I have a JRSC setup. So this should improve my hp numbers. I will post when I complete the install. Thanks to all for their thoughts and comments about this modification to the 1.6l. I appreciate all the help.

Make sure your COPs have internal ignitors.
