The 2020 Owners Manual in the US states:
Models with 18 or 20 inch wheels
Unleaded gasoline with a Pump Octane Number (PON) of 91 or higher is recommended.
I believe this is the Sport and Touring models, including the Sport Touring.
I view these technologies as more of a gentle assist that can help when you're driving tired. They can help prevent an accident, but are in now way meant to drive the car without the user being in control.
The KTuner and Hondata devices both come with basic tunes that bump up the HP a little by increasing the max turbo boost pressure. Two Step Performance sells a very popular tune that you can get for either device that does that and a little more. All three options are considered safe.
I've had both, the sedan is definitely better in clear weather, but in rain or snow the hatch has a rear wiper to clear the window whereas the sedan does not. I have the hatch now and prefer it for other reasons; the lesser rear view wasn't enough to make me get a sedan again. You still have the...

The Si and the Sport Touring Hatch both have everything I want, with a few extras I don't care about in the Sport Touring. I really want a hatchback so I just need to...
Perfect condition, unlocked, in original box. Only 2 months old. CARB compliant so it's fully street legal in all states. Selling because I'm getting a new car and don't know what kind it's going to be.

$495 list, selling for $250 delivered...
I want the features on the upper end like CarPlay, auto-down windows, keyless walkaway locking, push start, auto climate, etc.
All that plus the MT6 in a hatchback. The only option for me is the Sport Touring.
