I am also in the beginning stages of doing this research and was planning to do some sort of write up on it. I just reached out to Wheee! and have been digging through Duffy’s thread to get started.
I think this thread is as good a place to compile notes as any. This is what I have gathered, plus contributions by @Zed Head, @duffymahoney, @wheee!, and @madkaw (please suggest edits as appropriate):
Better Performance? - Yes, in the form of hotter spark, less chance of misfire, more efficient combustion, and better emissions
Better power? - Maybe. Full control of timing in any load situation is a far and above the compromise of a dizzy - however it might be recurved.
Lower cost? - Not initially, but parts are easier to find that the original setup once a system is in place.
Tunable? - Yes. Programmable ignition curves allow you to optimize for power and efficiency.
Spark Plugs (6)
Camshaft Triggering Device / Position Sensor / Angle Sensor
Crankshaft Triggering Device / Position Sensor / Angle Sensor
Ignition Control Unit / Module
Manifold Absolute Pressure Sensor
Tachometer Signal Converter
Cost - Is the cost of the system worth the benefits for your car vs OEM parts or other options?
Availability - Can you find replacement components to get your build finished and keep it working?
Difficulty - Will you need to have help getting it installed, tuned, and keep it working?
Appearance - Which of each component is right for your build style?
Heat - How will heat be managed to ensure proper function and longevity?
Positioning - How will you route the wiring through firewall and what mounting points will work for each component?
Accessories - Will you be running AC, the headlight relay harness, non-original alternator, other hard-wired electronics, etc.?
Smart Coils (from AEM Performance Electronics)
“Smart” Inductive Coils are designed for use on applications that do not have an external igniter.
Wasted Spark (from Wikipedia)
In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has no effect and is thus "wasted". This design halves the number of components necessary in a typical ignition system, while the extra spark, against much reduced dielectric resistance, barely impacts the lifespan of modern ignition components. In a typical engine, it requires only about 2–3 kV to fire the cylinder on its exhaust stroke. The remaining coil energy is available to fire the spark plug in the cylinder on its compression stroke (typically about 8 to 12 kV).
“If you're running a wasted spark system, you don't need cam sensor.
Two pistons will be approaching TDC at the same time. Of the pair, one of the rising pistons is approaching TDC on it's compression stroke, and the other one is approaching TDC on it's exhaust stroke. A cam sensor would allow you to differentiate between those two, but if you're running a wasted spark system, you don't care... Just spark both of them at the same time.
If you had a cam sensor, you could spark just the cylinder on it's compression stroke alone without "wasting" a spark on the other cylinder.” - Captain Obvious
