View Full Version : Anyone running or familiar with dizzyless LS1 coil pack setups?

Saw this over on TTF and found it pretty interesting. I didn't want to post over there as I'm sure I'd be flamed.

The guy had the AEM EPM, and LS1 coil packs on his 89' turbo car. He claimed the car ran much smoother throughout the entire RPM band and had much more accurate timing.

Any truth to this? What are the advantages to this? Looks like it wouldn't even be that much more costly after I sell my MSD dizzy, coil, and plug wires.

For the mustang?
I remember in one of my catalogs some one offering a distributorless ignition for the mustang's with its own seperate coilpacks for each cylinder.I just cant remember who it was.It was a couple years ago though.

Yep, I've seen several mustang guys with this setup since AEM came out with the EPM.

Can it really make THAT much of a difference compared to a mechanical dizzy?

As far as idling better than stock, I doubt it. Idling better than an AEM controlling a stock-style coil, there's a chance.

That's what I'm wondering. Everyone who I've seen that is running the setup nuts all over it :confused:

Any other gains?

Have they provided any data? I just don't see what the huge advantage is. I mean, run a MSD box and that should smooth out the waveforms, no?

A quick search came up with this. Because I don't know I can't endorse this, so keep that in mind.

"On an induction coil, it takes a finite amount of time to saturate, i.e. juice up, the low side coil windings. As engine rpm increases, the amount of time to saturate the coil diminishes as does the voltage out of the coil. Electronics guys have figured out better ways to trigger the signal to the coils but I do not think they have replicated what an induction coil does with anything other than an induction coil. By using COP, each coil gets more time to saturate because each coil won't have to juice up again until just before it is "their" cylinder's time to fire again. The COP arrangement produces high spark voltage that does not decrease significantly with engine rpm. Many economy engines are small displacement running at fairly high rpm, so COP has benefits there too. "

Another tidbit about it.




Coil on plug does allow for better spark management.

Dwell time can be adjusted individually per cylinder on some engines.

Better misfire detection.

Multiple sparks per combustion event possible.

Greater reliability.

Less effect on emissions during a failure.

No need for a "double" platinum style plug.
