Cool on both fronts, but can you not hang one to a coil, or send Jason only one coil... Or I can send Jason a coil. Or something.

Since I was getting the item shipped from the buyer anyway, I figured that I'd just send them directly to Jason to save time. Thanks for the offer though.

mine will be here Friday...hahaha, everyone is going COP.

Why wouldn't you? Cheaper then replacing the stock spark plug wires and a much better system overall.

i feel kinda special, being the second person to go COP lol, i know a lot of people are thinking about soldering to the pins, and filling it with epoxy, but what if one day you have to replace the coil?

Flipster! How's it working out for you? What ecu are you running them on again? hehe I'm all warm and fuzzy watching my brainchild grow. :)

Sign me up for connectors too. I haven't bought the plugs yet, but once I have the connectors that should be the easy part.

One weird thing I noticed upon taking off my coils- there dont appear to be any wires on the coil side of the harness so my hopes of making a plugable harness setup are stillborn. I guess I will just hack apart the stock harnesses to do the wiring.

Still, this seems very sweet. I can't wait to get mine.

i'm still running the stock ecu, i don't plan to go too crazy with it, as far the future goes with an ecu, i plan to do EMU, i have nothing really to compare my MPG with so i'm not to positive if my MPG went up, it seems really low, but then again i was told before that the 6 speed will do that to the car. I definetley enjoy knowing that all the little ignition stutters i use to have are all gone, and feel the car is much smoother, i even cleaned up the wiring a little bit more since my original pictures were posted

Awesum another success story showing noticable improvement. That was the goal plus the cost savings on wires. :bigtu: Post pics because you used a different coil so lets see how it finally turned out.

how many pounds of boost you running flippy?

1) Solder the wire to the coil
2) Fill with epoxy
3) cover with heat shrink (over the coil connecter and wires, mostly for looks)

I would run all the wires to the rear of the valve cover and connect them to the chassis harness with a weather pack connector. If one needs replacing in the future it is simple to remove the pins from the connector, stick the new soldered/epoxied coil in, crimp on new pins, and re-insert them. Weather packs are a god send.

Braineack 08-01-2007 06:06 PM

if you do quick-connects at each 4 wires, then you'd only have to re-epoxy that connector each time, not a big deal.

Actually dwell is more the time it takes for the magnetic field to build.

Magnetic field strength is proportional to current.

The primary of the coil is say 2ohm, 12 into 2 ohms draws 6amps. Drawing 6amps for longer then it takes for the field to build (dwell) is excessive. Dwell is a time variable not a current variable.

My 1.6 is officially running on COPs in wasted spark on the stock ecu. Hopefully sometime this weekend it will be running on MSII. I'll probly just keep it on ws for a while because I'm way to lazy to wire it up for sequential ignition right now.

Ben 08-02-2007 09:58 PM

Sweet! Congrats....

cjernigan 08-02-2007 11:01 PM

You MSII fockers make me think i should go that route sometimes.

lazzer408 08-03-2007 02:59 AM

Go AEM! $399 =)

Flippy02 08-04-2007 11:49 AM

could EMU be setup to run sequential? i was reading up on it, and saw it could be setup for 4 channel ignition

I don't think so. I'll look into it
