That is one thing a lot of people don't realize is that engines run cooler on higher nitro. If you have an engine that is marginally overheating with 10% nitro, you can increase the Nitro to 20% and it will make the engine run cooler. That is because it lowers the flash point and thus the fuel burns at a lower temp.
This also can help for people who live in very warm climates...

Indeed true. Engines running higher nitro do tend to run a bit cooler but not because of lower flash point.
Higher nitro requires a richer setting than lower nitro does. Richer means not just more nitro but more MeOH and heat dispersing Oil.
Tuning the timing of the typical 2 stroke or 4 stroke by mixture adjustment isn't the optimal set-up. YS's CDI promises superior tuning for timing and hence running. This lesson has been learned by the few in Pattern who tried ignition on earlier non-ignition equipped engines. YS marketing knows that introducing a "sure" thing, particularly because their equipment is popular in Pattern, will generate super returns.
And even I who am a staunch 2 stroker will look into this one. I really like the handling of the 2 stroke gassies so this is a no brainer
