The new ignition comes in three flavours.
L=Light, suitable for 2S lipo, and reverse running cut-off (26cc 35cc)
S=Standard, 2S Lipo, different advance curves pipe/canister, reverse running and choke operation below 900 rpm (45M and 58cc), Output for LED panel as option
P=Pro, 3S lipo, different advance curves pipe/canister, reverse running and choke operation below 900 rpm. (58 prosport), Output for LED panel

The ignition change is mainly a change to a different supplier. Apart from the lipo battery, there is not much everyday advantage over the Vlach ignitions. These engines start so well, that the automatic choke is not needed. On Aspen (Alkylate petrol) fuel using the feature would flood the engine and thus prevent starting. The extra choke servo adds weight and wiring, which is a point to consider as well.
Reverse running only happens at very low rpm and light props, and is easily avoided.
