Cool stuff, sounds good. Things go through this forum in fads it seems. Everyone jumps on megasquirt, a little WI, then COPs, what's next?

All cleaned up. Everything was fine when I started the car. Went for a ride, and the tach died. Everything else is fine. Tach works with original ignition. So there must be a loose connection. I'll deal with that later.

The 'stray' wire is an extra ground I ran from the harness, but haven't done anything with it yet. Figured I'd see how it works without the ground first.

Anyone know a decent source for the ignitor module? Or have one for sale?

AND.... we're done. Had a bad connection. You see, most of the joints in this harness were soldered. But in what I'll concede was not one of my smarter moments, I decided to play the "Is this hot?" game with something after I soldered it. I just wasn't paying attention, and when the burn came, it startled me and I dropped the iron, which broke the tip. That forced me to butt connect the few remaining joints. TWO of those butt connects had bad connections. I'll also not be taping everything up anymore
But we're fixed up, and it's all working now.

SOL,

I've got your coils and ignitor here.

Jay, the ignitors can be had for around $25 from the typical used parts places

fire, i made the plug out of a gutted ignitor. you can see the shell in the very first pic in this thread.

And that would of course differentiate it from mine, which didn't work at all. I got pretty lazy towards the end and didn't really put any effort into troubleshooting it. I wonder if perhaps I wired my triggers backwards as well? Guess I could check that easily enough... Quick project for this evening.

Joe did it just spin and never catch? If so, your triggers are probably backwards. Here's how mine work:
Trigger 1 as labeled on the ignitor goes to Coil 1 (and 4)
Trigger 2 as lableled on the ignitor goes to Coil 2 (and 3)

I didn't post pics of my solder job because yours looked sooo much nicer. But I feel better about it now.

Yup. The engine just spun, with no sign of ignition whatsoever. The reversal scenario confuses me somewhat, because I'd expect that a spark plug firing at BDC after a cylinder's intake stroke would be able to light off the uncompressed mixture, which should in theory bend a rod. Oh well. I'll try reversing them when I get chance.

yeah it's scary as [email protected]@@ actually. my engine spun fast like normal but without starting, then it took a REAL SLOW revolution and then a real fast one again. I had real bad thoughts in my head. But I flipped the COPs around, and it fired immediately. And I made it to HomeDepot and back just fine.

I set my gaps to .040-.041, increased boost via EBC to the settings from my dyno tuning, and went for it. It hits 13psi or so and holds 12 to redline.

I got ONE misfire, the first time I went into boost. The rest of the time, no problem on WOT through 1-2-3, no problem on pulls from 2.5k in 3rd or 4th, no problem stabbing the throttle in 5th.

I'll probably set the gaps back to the .037 range or so, to be safe. They were .027 before. Which is smaller than I remembered setting them, but a gauge doesn't tell any lies.

The wiring diagram that Lazer posted is incorrect for some cars then? The wrong set of coils is firing correct?

Ben you're going CR on us. I vote NO on the split loom. Don't you have some of the split smooth vinyl stuff? Looks like you've got hoses running to your cops now. You could run the hoses to your coil pack. :gay:
