I have a z6 I picked up a d17valve cover/coil packs/pig tails for free. I read about a sister board you could use some time ago on pgm-fi but I cant find it now. Anyone used it? Any one have the link?

I put the valve cover on looks like its all going to line up??

Why? There is no gain from doing this. Plus you do not exactly have the dwell setting to correctly fire those with the software your using.

Unless you are looking for street cred when you pop your hood, then I understand. COP gets the street cred, .

Ya I know my stock ignition system is fine. Ya it would be more of a hay look at my shit kind of thing. I also picked it all up for free. I have spent the last few nights digging threw pgmfi and cant find the little sister board or anything online for that matter besides converting to a stand alone.

I remember seeing something that some one had built but I cant find it now.

i posted a circuit over on ectune a while back. i've never tested it. probably has a bug or two to work out. for whatever reason, i can't post on the ectune forums anymore, so i said fuck it.

somehow, the 4AG guys have made this work:

it's batch fire COP! i'm not entirely sure how they're not lighting off at the bottom of the intake stroke, but they claim it runs great. probably runs the coils pretty hot though. not something i'd reccommend trying.

on a side note, the circuit i made does work.

There's something missing in the link, it's no worky

I bet the injector is opening after the plug has done it's thing a few degrees before bdc.

I thought the whole point of cop was to increase the available charge time between spark events and allow a coil design that could charge to a greater capacity with the bigger window.  

I'm sure those guys love the steering response they get from stretching their tires too.

fixed the link.

not at high load. the injector is open well before the intake valve even opens for the intake stroke at higher loads. i'm guessing it has more to do with the fact that the mixture is still pretty uneven. i'd be willing to bet there would be a lot of preignition in a turbo engine under the same conditions.

charge time was kind of the idea, but most of these coil units have charge times in the sub-3mS range, so crome's dwell time is actually a bit longer than necessary. shortening the dwell is pretty easy though.
