It runs a split. Just like I said, there are 2 coils packs with 3 coils each. There are 3 leading and 3 trailing. There is not an OEM N/A 20B configuration, all the Cosmos are twin turbo.

20B coils

Thanks for the info and pics.

Does each of the coils on the three pack have a separate trigger. Onlike the FD leading(1 trigger for both coils)? trying to figure how the split is obtained.

Yes, each coil can fire independently. The is a 4 prong connector, 1 power and 3 negatives to fire the coils.

You know I've never seen anyone re-use the 20b coils! How come? Seems like they would work well if your trying to be efficient with space and also make good spark with an universal HKS twin power no? My engine didn't come with them. It would have been nice to experiment with them.

Ok, some update finally.
I had friend to help me out with some electrical stuff on the car and he has something like this :

http://www.fluke.com/fluke/usen/port....htm?PID=70366

He does air powerplant maintenance for living and knows his way around. And he knows how to use that thing, i probably wouldnt.

Anyways, he put probes into each of the wires going from ignitor to coils and showed me waveform with twinpower disconnected, and then connected. Even me, could tell the difference at first look. We were quite busy, but next time i will try to take pictures of both waveforms and post them here.

While we were doing this testing, we found one of the signals was out of ordinary and few minutes later we found cause of it - nut holding wire on the coil was loose. You wouldnt notice it on engine's idling, but under boost/high rpm it could have caused improper spark....

Just to be sure i pulled UIM, tightened and glued all those nuts...

So, final resolution : yes,my twinpower works and its measurable with proper equipment...

Can you remind me which HKS twinpower are you using? and can you notice the difference between with and without?

Also, also if 6 channel, how did you wire it.. Banzai way?

Universal 6 channel Twinpower DLI

Difference on scope, yes, difference by the sound of engine at idle? No

i think they don't get used for a couple of reasons. some people probably don't get em. and then the other problem is that the ignitor (which is separate) is weird.

the ignitor works on a toggle like the trailing FC, but instead of toggling 1 and 2, its 1-2-3 PLUS there is a confirmation signal back to the ecu
