I too am interested in a coil pack ignition system to do away with the problems of the optispark, but have a couple of questions about it. one question i have is will this eliminate the problems from moisture damage that can be caused by pressure washing? also, would the delteq system be a better choice due the fact that they offer a kit to mount either on one valve cover, or on the radiator mount? any feed back would be appreciated.

Both the Delteq and LTCC systems are safe for pressure washing. All fittings are water tight. The opti is only used for timing. No voltage of any kind flows through the opti.

I've been searching....and I haven't really come up with anything that seems to be 'mainstream'....and I can't believe that no one has come up with a conversion that totally eliminates the optispark unit, uses a crank or cam position sensor and a coil on plug setup.

It is not safe for pressure washing. It still uses the Opti for timing. If your optical eye gets wet it toast.

There is more than one way to skin a cat.






Ford EDIS8 Conversion using GM coil packs. Rock solid spark, limp home mode and 50* of available adjustment. Cheap parts available at damn near every salvage yard and easy to wire up.

Though this option is no good if you are using the stock ECM. I'm contemplating converting it to C.O.P (only requires changing the coils and a little tweak to the wiring) but honestly the gains are negligable. I'd rather spend the effort elsewhere.

It's a Ford EDIS8 system off of a Police Interceptor Crown Vic. It's a simple but rock solid system. It uses a 32-1 tooth crank wheel, a crank sensor, module and coil packs.

I have a a whole section about EDIS 4/6/8 below.

http://www.projectlt10.com/content/m...index.php?id=1

The Accel DFI would work just fine with this setup. I'm using a Megasquirt to control mine. It is also compatible with the MSD DIS+6 boxes. There is even a stand-alone controller for using it on carbed applications.

While it's not high-res like the Opti (i.e one pulse per degree of revolution), it is more than sufficient for 99% of the engine combos out there.
