On the TriSpark at least it works really well! 
I ASSUME it's just an auto-retard of the timing at very low (kick-start/e-starter) RPM. That's an easy thing to do electronically and really, there's not much else an add-on ignition system could do other than adjust timing.

On the Boyer digital the idle stabilisation is by the advance of the timing as the revs drop as advancing the timing increases the revs, if they drop further than the idle stabilisation bit of the curve ie down to near kicking revs then the timing is retarded.

Sounds like a really useful feature. Getting a stable low idle on a Commando with two Amal Concentrics when the bike or weather is hot or cold has always been a challenge. Does this feature work well? Do some brands of ignitions do better than others regarding this feature??
To have idle stabilization it has to be a digital l type ign. The standard boyer MK 4 , pazon sure fire are an analog type along with the rest of the low end priced units
Russ. Concours on here has been fighting kickback issues with his altair like me with the boyer micro digital. What other components do you have in your ign? Mu next thing to try to cure my kickback is resistor wires along with the 5k caps

I have a RevTech dual tower Harley type coil - 4.5 Ohm primary winding. Wires are stranded copper wire with the NGK 5K Ohm plug caps. (Always check the resistance of these plug caps. They can go open. There are fakes too.) Plugs are Champion N7YC.
My friend had a problem with his new Altair kicking back. He worked with Andy at Pazon and got a modified version. He said it was a little better but still was not happy so he returned it. Note... He can't start my bike either but it starts 1st kick for me even after sitting months. He weighs about 175 lbs and I'm at 210. We've had our Nortons since June 1972 and we are both age 68. His bike is a 1971 standard everything and now a new CNW starter!
I would want to try a Trispark but can't bring myself to trust the reliability.

sounds about like what i have. a drag specialty 4 ohm dual tower coil just changed the wires to resistor type lucas 5K caps and NGK bp7es plugs. the wires seemed to stop the kickback issues with my boyer micro digital. I don't blame you for staying away from the failspark. in the end i was in to one for $600.00 dollars with the failures i had. like i posted the last one went out before i used up a rear tire.

You are right. The thread is about stabilization. Somehow I managed to get into just thinking about anti-kickback/starting. The last thing you would want for starting is ignition advance. But stabilization, once the engine is running, is easily controlled by simply varying the timing. Sorry for accidentally hijacking myself into the wrong subject!
