Hay there,

I'm askin this becouse i dont want anny sparkplug wires going acros the engine so i can mount 8 small coils on the inner fenders and still use wasted spark.

thanks

If you do a search on EDIS COP (coil on plug), you'll find a bunch of info related to EDIS, Waste spark, and COP's (or 8 coils as you're referrring to them).

I've been running an 8 COP EDIS-8 setup (waste spark) for quite a while now with no problems, and the car runs extremely well. You'll want to wire the pairs of coils in series.

Can I ask what car your COP's came off of?

Thanks

Allen,
The COPs came off of a 2003 Ford Mustang Cobra, they were actually specific to the valve covers that I was using.

Thanks, I'm trying to find some for my V6 Nissan motor, I believe they need to be the two wire type can you confirm that?

The ones that I'm using are the two wire type.

Thanks,
I think that's the general rule for an EDIS COP install, must be 2 wire instead of 3 wire.

Correct,
EDIS can only drive the +12v/GND style coils, not the logic level, 3wire style.

So, if i read right i can use 8 coils with .7 Ohms and use them as wasted spark.

Just figuring out to wire them up, can't be that hard to do huh.

Main problem to find COP's, i live in Belgium and these are realy hard to find here.

For each channel, you'd wire as follows (for ford small block firing order, 13726548):

+12v switched -> coil 1 +
coil 1 - -> coil 6 +
coil 6 - -> EDIS Channel 1

And so on for each of the cylinder pairs. (1&6, 3&5, 7&4, 2&8 )

Your firing order might be different, so you'd combine differnent pairs.
