Read what I posted again more carefully. I never said anyone was not going that route, in fact quite the opposite. I said regulatory obstacles ("FAA paper") were standing in the way of large scale adoption as well as corporate welfare for proprietary boutique fuel's was the wrong direction. "Solving" aviation fuel problem, once and for all, requires we look at convergence of the AvGas and MoGas fuel chains, at least as much as possible. Creating yet another boutique fuel, subsidized on the taxpayers dime, is not a solution.
Let me give you some details to support my earlier contention. Water injection... a very mature technology around since at least WW2. Peterson did a STC on this some decades ago that eventually made its way to InPulse, who sells a STC to allow IO-470's and IO-520's to run on 91UL Mogas:

Problem is, they want $14,000+ for it for my Baron 58, for what amounts to a $500 water injection system along with a controller that turns it on when CHT is above 400F OR MP above 25". Not speculation on my part, the experimental guys are already doing it:

As to FADEC's, those are a win/win, retard the advance under conditions prone to detonation, advance it during cruise to gain some fuel economy. Even detect pre-detontation similar to how Harley does it on their air cooled motorcycle engines.

Here is the thing, the FAA/Congress have dumped over $26 million into trying to come up with a "replacement" for 100LL... which at the end of the day will result in a monopoly for whoever gets the nod as well as another more expensive boutique fuel. What I'm saying is this:
Take the lead out of 100LL... that gives us 91/96 or 94UL depending on the testing standard. My Aztec was already placarded for 91/96 so we are done there as we are done for about 75% of the remaining GA fleet. Now you are correct much of the 100LL is used by the turbocharged/airfreight market, and that is where the technology comes in. What if the FAA gave Peterson/InPulse a million dollars to expand the number of aircraft that are covered by their water injection system? GAMI some bread to finish their FADAC PRISM system?
Now I'm not a fan of government grants, but I'm less a fan of government creating monopolies. Any solution has to be market based and have competition. And IMHO has to, as much as possible, not drift even further away from the existing automotive fuel chain.
That being said, I fully realize the pipe dream squarely rests on my shoulders. I had really hoped the FAA would give the nod to the PNC category when the ARC proposed it, but it was not to pass either.
