COP Ignition Development

Yes I can drive those coils. My driver circuit is also logic level driven.

My current limit is however adjustable and accessible, so there is greater flexibility, and ability to monitor and control peak current. Setting the dwell for, "whatever you want", without viewing current? Bless your heart.

The ability to measure the primary voltage is also important for me. It is a window into what is happening at the plug. The primary voltage is available at the collector of the driver transistor, that point is not available on the LSx coils.

The coils I am using, have a more advanced magnet biased core, so they are more compact.

Plenty of information about these coils out there. Known as D585's....including the stock tables. Dwelling mine at 4ms at 14V, which seems like it's more than safe enough, and actually slightly less than the stock table. In normal air it sounds like you're using a tig welder. Absolutely no misfiring, and the plugs are totally clean. These coils get swapped on pretty much everything anymore. If the supra guys using crazy high boost and still running a decent plug gap and they're working, I'm sold.
