100 octane?

Just wondering if anyone has any information on tuning LNF for non-ethanol 100 octane unleaded. I have it available to purchase at the pump. I know a lot of guys do the E85 but just wondering if a 100 octane tune (or a blending it anywhere between 91-100) would be something worth trying before i upgrade to facilitate running E85. The 100 octane isn't cheap but the car doesnt see a lot of drive time.

I mean the reason people run e85 is the cost difference and additional cooling from the lower flame temp and higher volume of fuel. I wouldn't see any issue with getting setup to run 100 octane if you're fine paying the cost difference, if you're not wanting to upgrade the entire fuel system just run an e47 blend. You'll get the same timing or close to the same timing and the stock fuel system should be fine.

Plus the 100 octane smells so good! I've had quite a few people inform me I have a coolant leak when they
follow me and get a good whiff of my E47 lol.

There's no trick to it vs pump gas. Stoich is the same. Just gives you room for more boost/timing.

In general, you can run more timing and/or more boost with more octane
